White cement: application, characteristics, advantages, brands. White and colored cements, their features and application in construction White cement application

Even those people who are not particularly versed in the construction industry probably know that it is impossible to create a modern structure without the use of cement. Specialists in this field can tell more - about its types and brands, which have quite different quality characteristics and costs, unusual shades of this material, for example, white cement, are of particular interest.

It has found its application in the manufacture of high-quality artificial stone. The material is an indispensable basis for the creation of both colored and white concrete, high-quality dry adhesive mixtures. It is used to make decorative stucco parts for decorating rooms, stairs, borders, columns.

In addition to its original color, white cement is a substance that has good weather resistance, frost resistance, does not react to the effects of sulfates, and has a high degree of strength. Of the main disadvantages inherent in it, it should be noted a low hardening rate, a lower corrosion resistance than that of gray cement, and increased shrinkage rates.

Manufacturing process

The quality and decorative properties of this building material are largely determined by the special technologies of its manufacture. Raw materials in such production can be limestone and kaolin, which have a minimum capacity of manganese and iron oxide, which give a gray color to ordinary cement. To prevent possible contamination, the clinker is fired in furnaces running on petroleum products; the use of gravel instead of conventional metal balls helps to eliminate contamination of the clinker during grinding. As you can see, white cement, the price of which is somewhat higher than that of its gray "brothers", has a more complex and expensive manufacturing technology.

Application area

White cement is used as a basis for the production of white and colored concrete, and in order to achieve the highest quality of the colored material, clinker is crushed together with the cement at the stage of cement production.

The high aesthetic characteristics of the material make it possible not to subject the surfaces made from it to finishing, but if desired, they can be roughened or mirror smooth. Interesting in appearance, terrazzo material, surprisingly similar to natural stone, is obtained by adding marble chips to concrete. They look original when laying which used a solution of white color or having an unusual beautiful shade.

The high reflectivity of surfaces made of white cement is important. This property of the material is readily used by builders in the construction of tunnels and roads in order to increase traffic safety at night.

Since white cement is a somewhat unusual material, care should be taken to ensure cleanliness and the absence of rust on machines and tools that will come into contact with it during work before buying it. The water that will be used to prepare the solution must also be clean. Steel reinforcement before work should be pre-coated with a layer of gray concrete.

For those who are going to use white cement, it can be clarified that it is produced under two brands: M500 and M400, the degree of whiteness of the material determines its grade (there are 3 grades). White cement is produced in Russia, Turkey, super-white material of the highest quality is supplied by Denmark.

Today, white cement is often used in construction work, which has excellent aesthetic properties and excellent technical characteristics. The white color of the material allows it to be used to create various architectural forms, including sculptures.

Peculiarities

White cement is a material that is in demand due to its light shade, which is obtained by applying a special production technology and the components used. It is made on the basis of low-iron clinker, and it also contains mineral additives, gypsum, limestone, chlorine salts, thanks to which the material acquires such an attractive color. At the same time, the content of manganese and chromium is practically equal to zero.

All components can be fired, after which quenching is used. This process guarantees the strength and reliability of white cement.

This material is characterized by functionality, since it can be used not only in construction, but is also used as one of the components of dry mixes for finishing work, as well as for creating self-leveling floors.

The technology for the production of white cement is carried out in special mills-crushers, which crush clinker and other raw materials (porcelain, basalt, flint slabs). The fineness of grinding white cement is higher than that of the gray counterpart, because it is 4,500 cm² / g, and for gray cement this figure is 3,500 cm² / g. The burning of the material is carried out through the use of gaseous, liquid or other fuels that do not emit ash or soot.

After firing, the cement is cooled in an acid-free environment, while there is a sharp change in temperature conditions from +1200ºС to +200ºС. Cooling can be done with water, then the firing temperature reaches +1500ºС, and water - +500ºС. To dry wet clinker, a drying drum is used, which has a temperature of +300ºС.

So, there are two main ways to make white cement:

• Dry. This method is quite common, since many large companies prefer it due to the low moisture content of the raw materials. In special shaft furnaces, grinding, mixing and drying of all components are carried out. The clinker can be fired at a temperature of +800ºС.
• Wet. The hard components are ground in a special mill, and the soft ones are placed in a masher, using water. After grinding, the sludge is dried and amenable to further crushing, as in the dry method.

Today, the most popular on the construction market are two modifications of white cement - M400 and M500 when tested according to GOST 310.1-76 and 310.4. -81.

Since this material is characterized by a fineness of grinding, mesh No. 008 is used for its sieving, while no more than 12% of the raw material goes into the sediment.

White cement has the following advantages:

• Strength, reliability and fast hardening. After 16 hours, the solution hardens by more than 50%. This ability saves money.
• The material is protected from destruction under the influence of chemical solutions and moisture due to dispersion.
• Environmental friendliness is achieved through the use of mineralogical components of natural origin.
• The stability and strength of finished structures is due to the resistance to the formation of chips and cracks. This feature significantly reduces the cost of restoration or repair work.

• Attractive appearance.
• Color stability, because the cement does not fade when exposed to sunlight.
• The versatility of the material lies in the ability to be combined with various decorative materials for decoration.
• Functionality - white cement is used as a decorative and building material, is part of putty, grout, colored concrete and various dry adhesive mixtures, and is also widely used in the creation of bricks and floor slabs.

If we talk about the shortcomings of white cement, then it is worth noting its high cost compared to its gray counterpart. Some users do not perceive white cement as expected, but call it something between clay and cement. Some buyers point out that many white cement formulations contain a large amount of additives, which does not correspond to the composition on the package.

Today, white cement is used in almost all areas of construction work. In some cases, you can't do without it at all. It is excellent for building facades., because it gives them not only reliability and durability, but also expressiveness, attractiveness and beauty.

Due to excellent technical characteristics, this material does not change its original color. It can be safely used not only for external work, but also for internal use. He is not afraid of the effects of the weather.

Kinds

Today, manufacturers offer several varieties of white cement to meet the needs of various industries and achieve their goals as quickly and conveniently as possible.

Depending on the strength of the composition, the following grades of white cement are distinguished:

• M400- characterized by high frost resistance, low sulfate resistance. Shrinkage deformation and hardening rate are medium.
• M500- attracts attention with good frost and weather resistance, medium sulfate resistance. The shrinkage deformation is low and the hardening rate is medium.
• M600- has high frost resistance, quickly hardens, practically does not shrink, and is also characterized by low sulfate resistance.

White cement has three varieties depending on the reflectance, such as:

• the first grade is the highest because its reflectance is 80%;
• second grade - 75%;
• third grade - 68%.

Each manufacturer indicates on the packaging the degree of whiteness and the grade of cement. These indicators are the main ones when choosing the appropriate option for the implementation of the goals. They have an impact on the cost of production, as well as the appearance of products in the manufacture of which white cement is used. The Turkish-made "Super White" cement is on sale, which has a reflection coefficient of about 90% and is marked M600. The cost of one bag averages from 700 to 800 rubles.

If we compare white cement with a gray counterpart, then it is worth noting that the maximum grade of the second is M500. The decorative grade of snow-white material is marked M700. It is manufactured according to the latest innovative developments, its technical characteristics comply with European building codes.

It is worth noting that due to fine grinding, this material is characterized by increased shrinkage.

Marble is often used to create a durable, reliable and beautiful floor. Marble-mosaic options, for the manufacture of which marble and cement are used, are in great demand. Decorativeness attracts the attention of many buyers, since manufacturers use not only white cement, but also colored cement (red, green, yellow, beige, light blue and others).

Manufacturers

On the construction market, you can find white cement from various manufacturers - Iranian, Egyptian, Danish and, of course, Turkish. The cheapest product is from Iran, but cheap does not mean high quality. It is worth getting acquainted in more detail with well-known manufacturers who are famous in many countries of the world.

Aalborg White

The Danish cement plant Aalborg White has earned a reputation for using clean raw materials and advanced manufacturing techniques. Brand products can be found in 80 countries around the world, because it attracts attention with excellent whiteness and increased durability. Today, the company's factories are located in Malaysia, China, Denmark and Egypt. But besides the advantages, the products have one significant drawback - the high cost.

White cement brand M700 from Aalborg White has the following technical characteristics:

• the degree of whiteness is 85–90%;

Cimsa

This company is a very famous manufacturer of building materials not only in Turkey but also in other countries. In addition to decorative white cement, she produces decorative plasters, various putties and grouts.

White cement from Cimsa is ideal for creating arches, fountains, columns, balusters, statues. This material does not require painting in the future, since it is protected from fading and is not afraid of various weather phenomena.

Turkey is the birthplace of white cement, and the company's products fully confirm this by creating a durable and sought-after product. High quality at an affordable price is the main advantage of Cimsa products.

White cement brand M600 from Cimsa has the following technical characteristics:

• the degree of whiteness is from 92 to 97%;
• compressive strength after 3 days - 37.0 MPa, after 7 days - 49.1 MPa and after 28 days - 60.7 MPa;
• shrinkage is only 0.01%;
• the beginning of setting occurs after 100 minutes, and the end - 130 minutes;
• density is 3060 kg/m³.

Adana

Another popular Turkish manufacturer is Adana. It ranks second in the market after Cimsa and is a well-known exporter of construction products, including white cement.

Among the huge variety of materials that exist in the modern construction market, cement rightfully occupies a leading position. Due to its practicality, versatility and attractive cost, it is widely used in various fields of production.

The basis for the manufacture of cements are mineral lime and clay rocks, supplemented with a complex of mineral additives. At the same time, materials produced in different regions may have significant differences. The reason for this is the different composition of the rocks that act as the feedstock for their manufacture.

White as snow, hard as stone

One of these varieties, which has specific differences from materials of a similar type, is white cement - a powdered binder of a very light, almost white hue. The material acquires such a color and individual characteristics due to the use of special types of raw materials and a special technology that gives it not only an unusual color, but also increased strength.

As a raw material for the production of this composition, low-iron clinker with a minimum content of chromium and manganese is used, enriched with various types of additives, including limestone, gypsum and chlorine salts, which directly affect its color.

A distinctive feature of white cements is their high fineness of grinding, characterized by a solid residue on a sieve of 0.08 in 7.8 - 10.8%, with a specific surface of 360-400 m2 / kg. If we compare the size of its fractions with standard gray Portland cements, we can see that the fineness of white cement is about 4500 cm2/g, while for gray cements this figure is 3500 cm2/g.

In addition to a better structure, the material also has a high curing speed, ranging from 60 to 170 minutes at the initial stage and from 165 to 255 minutes at the end of the process. It is marked, in accordance with the strength indicators, indexes M400 and M500.

The specificity and special production technology makes white cement a rather rare material, which is produced by a limited number of companies from around the world. The most famous manufacturers of white cement mixtures are Egyptian, Turkish and Danish companies that produce products of the highest quality.

This is what the packaging of finished white cement looks like

Distinctive characteristics of Egyptian cements are a pleasant light color and excellent initial strength, determined by the M600 grade. In addition, it has increased wear resistance and a high average whiteness level of about 87%.

In the construction markets of our country, you can also find high-quality white cement from Danish manufacturers. Distinctive features of white cement Aalborg White can be called high early and standard strength, with periods of 2 and 28 days, respectively.

Pure limestone and fine-grained sand are used as the basis for its production. It has a pronounced uniform white color, practically does not contain alkaline compounds, has a high sulfate resistance and a high content of chromates, the amount of which is about 2 mg/kg.

Turkish-made white cement has been in constant demand over the past few years. Turkish white cement is a fast-setting material with a high tensile strength. Corresponds to the Russian brand M600, which confirms the compressive strength index. The high quality of the product is evidenced by its light reflection index, which is from 86 to 90.13%.

What does white cement look like when working with it:

Features of the production of white cement

As one of the most sought-after and frequently used building materials, cement, including white, is produced in several ways.

These include:

1. wet;
2. semi-dry;
3. combined;
4. dry manufacturing methods.

The manufacturing process begins with the extraction of raw materials, subjected to grinding and turning into a mixture with fractions of the same size and shape. Then the resulting composition is sent to special kilns for firing, after which various additional components are added to it. The result of this treatment is the appearance of a fine powder, characterized by a pleasant structure, balanced composition and light shade.

To achieve maximum whiteness, the cement can be further treated by exposure to water or an oxygen-free environment, as a result of which an increased formation of C6AF2 and Fe2O3 compounds occurs, and the original material acquires a more pronounced white color.

However, despite the huge number of advantages, such as practicality, a long period of operation, an attractive appearance and ease of working with the material, which deserve solid "fives" on a five-point scale, it has a significant drawback - high cost. For this reason, many are thinking about how to make white cement with their own hands.

There are many recipes for the preparation of cement compositions, differing in labor intensity and quality of the final product.

Here is one of them:

1. Take 6 servings of mastic, 1 serving of white lead. The components are ground to a powder, after which melted white wax is gradually added to the mixture.
2. Such a mixture has a high bonding ability and can be used as a base for masonry of varying complexity.

Areas of use

The main scope of the material is the manufacture of plaster mixtures for the production of facing works. In this case, Danish white cement is often mixed with various colored pigments, giving it a certain color. In addition, it is used in the process of manufacturing products of varying complexity, for example, paving slabs, balconies, ornaments, sculptures, cornices, etc.

Due to its visual appeal and excellent strength characteristics, white cement is widely used in various sectors of the construction industry, including:

• in the creation of mixtures and compositions of various shades;
• in the manufacture of elements of landscape gardening and architectural design;
• production of products with high ergonomic qualities and attractive appearance, such as flowerpots, stairs, balusters and railings, various types of fences, etc.

Using white cement at home, you need to know how to dilute it and carefully follow the technology for preparing the solution, based on the information available on the product packaging. It is diluted in the same way as the analogue of the traditional gray color: 3 parts of sand and 1 part of cement are taken, thoroughly mixed and filled with water.

Pros and cons, consumer reviews

Among the main advantages of white cements it is worth noting:

1. good workability, ductility and excellent strength properties;
2. the possibility of using as the main material for finishing surfaces of various types;
3. high aesthetic characteristics and ergonomics. In this case, using a standard scale of five points to evaluate the material, it is possible to assign a well-deserved "five" to this cement.
4. high resistance to any external influences, etc.

On the basis of a white cement composition, you can prepare compositions of any shades yourself.

The main disadvantage of white cement is its high cost. In addition, some consumers are quite critical of him, arguing that this material cannot be called cement in the truest sense of the word, since it is a cross between cement and clay. Some of them also noted the presence of a large number of additives in white cement compositions and the discrepancy between the declared grades and the contents of the packages.

Colored decorative cements: characteristics, composition, features

In addition to gray and white cements, modern industry produces compositions of various colors containing a minimum amount of ferruginous and other pigmenting components.

Colored decorative cement is obtained by simultaneous grinding of white Portland cement clinker, as well as gypsum and light-alkali-resistant colored pigments, supplemented with special type additives.

At the factory, decorative compositions are produced based on Portland cement in white, green, yellow and black shades of various intensities. To give the material other color options, special coloring pigments are used that can be used at home.

Various colors of decorative cements

"Subtleties" of manufacturing

Decorative cements get their color in the process of grinding white clinker, when dyes are added to the source material, crushed to the appropriate state. Mummy makes it red, umber makes it brown, ocher makes it yellow, chromium oxide makes it green, soot makes it black, and ultramarine makes it blue.

If necessary, colored cement can be made with your own hands.

To do this, you must follow the following rules:

• the maximum concentration of the coloring matter in the total mass of the mixture should not exceed 5%;
• do not overdo it with the amount of sand that drowns out the color and reduces the plasticity of the composition;
• mix the components very carefully.

Application and cost

The main area of ​​application of colored cements is the creation of various architectural forms, where they are used in the form of mortars, concrete compositions and whitewash. In addition, they are used for lining panels and blocks and are part of cement paints.

As for the cost of this material, it is an order of magnitude higher than the analogue of the traditional, gray shade. You can buy colored cement at any hardware store. The average price of a package of M500 brand material is about 410 - 490 rubles.

Use of colored cements for decorative finishing of buildings:

Advantages and disadvantages of colored cement

The main advantage of the material is its high ergonomic characteristics and visual appeal, due to which it is used in the design and decoration of interior and exterior parts of buildings. At the same time, when using colored cements, not only the surface of finished products is painted, but also the entire mass of concrete, due to which a more pronounced aesthetic effect is achieved.

However, it also has some disadvantages. One of them: increased shrinkage through the use of coloring pigments. In addition, when low-quality dyes are used, salt deposits can appear on the surface of concrete, which worsens the appearance of finished products. In general, this material is of high quality and wide application possibilities.

Probably, every person at least once in his life has come across construction or finishing. Or at least watched it happen.

Everyone knows that any construction process involves working with white cement.

The use of this composition is widespread in construction, in the creation of sculptures and various architectural forms. When a person talks about cement, he represents a gray homogeneous mass.

Indeed, before this material had only this color. But, modern markets are now filled with a brand of cement that is beautifully white. It refers to a composition that is distinguished by its characteristics and aesthetic properties.

In addition to being used as an individual material, it can be added to various other formulations. Only some features associated with the work of white should be taken into account.

White cement is a light powder.

When in contact with a liquid, it becomes solid, therefore it is characterized by sufficient strength.

It is identical to ordinary cement, but is made using a special technology using some additives.

It is they who give the material white.

Additionally, this material has a high atmosphere resistance. Therefore, it refers to a fairly durable material.

The composition of white cement includes:

• white clinker
• active mineral supplement

To bleach clinker, gas is often used. It is based on a decrease in the degree of oxidation of dyes.

The main parameters of white cement are:

• whiteness - 85%
• sediment up to 0.12%
• the material reaches a hardness of 65% after just 15 hours
• cement has compressive strength: in three days - 38 MPa
• frost resistance of the material is 100 cycles

Frost and moisture resistance allow the use of cement under the most adverse conditions of exposure to the atmosphere. At the same time, it will not crack, crumble and break off.

Pure color and good structure are achieved due to the use of special raw materials and innovative materials.

All substances that are part of the material contain a small amount of iron oxides and pigment inclusions.

The clinker is to be calcined.

Then it must be cooled down. Such actions increase the resistance and frost resistance of the resulting cement.

To make the color of the material whiter, the clinker is treated with water. This procedure enhances the color.

Thanks to this, the latest brands of cement look quite nice under the rays. But, this material has a high cost, so it is problematic to purchase it. However, white cement is widely used in construction. The use of material at home is just beginning to find its place.

Advantages

This material has recently entered the construction market, but has already established itself as one of the most popular compositions. White cement has a large amount of:

• Excellent strength and ability to harden quickly. After sixteen hours, the degree of hardness of the material is sixty percent. Therefore, the duration of the construction procedure is reduced, and, accordingly, simplified.
• Does not collapse when interacting with aggressive solutions and atmospheric moisture.
• Environmentally friendly material, harmless to humans.
• Structures made of this material are very stable and durable.
• The complete absence of cracks and chips, which minimizes the cost of.
• The presence of color stability and aesthetics of whiteness, which makes it possible to combine cement with other materials.
• A multifunctional composition that can be used both in construction and repair work, and in the manufacture of architectural sculptures.
• The material is widely used in the manufacture of bricks, concrete, grout and other similar compounds.

This type of cement is a fairly practical building compound. Buildings that are built with it will not shrink much. You can also see that they do not crumble. But, this material also has disadvantages.

These include the need for increased attention. When working with this material, certain rules must be observed. Also, the disadvantage is the high cost of the material. But, it is worth noting that quality materials are always not cheap. And if you take into account the duration of use and durability, this is quite profitable.

Features of use

Sometimes when finishing work, people use white cement. Application, how to knead it, does not cause any particular difficulties.

White cement is diluted identically to conventional material. But, when working with it, you should take into account several features:

• Tools must be perfectly clean, otherwise you will get a dirty color. This applies not only to dirt, but also to rust or mold.
• All containers must also be used only in a clean state. The same applies to the surfaces to be applied. Otherwise, the desired effect will not be obtained. The cement will stain and stain.
• It is impossible to allow the application of cement on surfaces with the presence of mold and, since work will take place with a light mixture. As a result, all the work will go far for the future. In any case, the color scheme will be violated, not to mention the appearance of various spots on the surface.
• Sometimes fillers and other compounds are used in the work procedure. Their color should be exceptionally light. It is strongly not recommended to add clay or something like that. Otherwise, the purpose of this material is simply lost.
• If cement is applied to metal surfaces, they must first be treated and protected with anti-corrosion agents. The thickness of white cement should not exceed three centimeters.
• White cement has a decorative value, so it should only be diluted clean.

If a person adheres to all the above rules for working with white cement, he will always be satisfied with the result of his labors.

Scope of application

This material is used for decorative and industrial purposes. After all, it is white cement that serves as the basis for the production of adhesives and grouts.

It is used in road markings, as it has a reflective property. And even this is not the last scope of its application.

With private use, due to whiteness, this material is purchased for the following purposes:

• Facade finishing. It is preserved for a long time in its original form. Also, the surface will not fade in direct sunlight.
• Independent production of grouts, plasters and the like.
• Reconstruction of decorative structures. For example, sculptures and architectural works. Therefore, this material is used not only for production purposes, but also at home, in most cases in household plots.
• Basically, white cement is used to make decorative elements and decorate existing surfaces. With it, you can recreate beautiful surfaces of various textures.

This is a material with increased strength, which has a huge scope in various fields. Its main advantage is a long service life. That is why it is widely used and has already managed to establish itself as one of the most sought after.

What to consider when mixing the composition

White cement must be mixed under specific conditions. It will change properties upon close contact with fat. That is why when mixing the material it is required to take clean tools and containers. In addition, it is recommended to degrease them before use. Metal surfaces must be treated with anti-corrosion compounds. They are applied in a thin layer. Otherwise, the resulting rust will penetrate the structure of the concrete and be visible from the outside. Of course, this will not happen immediately, but after a certain period of time it will definitely happen.

Otherwise, this type of cement is identical to conventional material. It can be easily prepared. Pure river sand can be used as filling cement.

For the manufacture of the composition, standard doses are required: one to three. Mixing this composition will not cause any special difficulties even for the most inexperienced person. Special skill is also not needed here.

• use only clean tools and containers
• the liquid with which cement is diluted, only pure
• when using steel reinforcement in work, it is recommended to pre-cover it with a layer of concrete, approximately thirty millimeters
• the use of a bleaching agent titanium dioxide is allowed - at the same time, the proportions should not exceed one percent
• all used aggregates are white and fine fraction

White cement - composition, application, where to buy. If you're wondering what to choose from the vast array of white cements available at any hardware store, you should read this article. Along with gray cement, there is also white cement on sale, which differs not only in color, but also in cost. You will learn what white cement is, what advantages it has and what it is used for.

So you will know whether this material is suitable for the work that you planned to do or not.

Distinctive characteristics of the material are:

1. White color. In building materials, light shades are achieved due to the peculiarities of the composition of raw materials and a special production technology.
2. main component. The main component of the material is low-iron clinker, to which crushed gypsum, kaolin, limestone (crushed) and chlorinated salt are added in clear proportions and sequence.
3. Combination of components. The characteristic white color is obtained by combining chalk and kaolin. With the right choice of raw materials, in particular components, the finished material contains very little manganese and coloring oxides.
4. Strength. White Portland cement differs from gray cement by a high level of compressive strength (up to 60 MPa). Such strength is achieved due to the rapid cooling of the mass of the clinker type after firing in an environment in which there is no oxygen.

Note, that when burning clinker in a kiln, liquid-fuel or gas burners are used, which do not produce soot and ash. This is a rather important condition, since if the technology is followed, white cement M500 with a characteristic color is obtained.

In accordance with the parameters of strength, there are:

According to the reflection coefficient (degree of whiteness), the material is divided into three grades:

• The first is from 79 to 85%.
• The second - 74%.
• Third - 67%.

Belonging to one of the described varieties and the degree of whiteness are indicated on the packaging. It is on this that the scope, the cost of the material and the final appearance of the products, which are made from the selected cement, will depend. Now in construction markets you can buy Turkish white cement of the M600 brand “super white”, the reflection coefficient of which (!) Is 90%. For a bag of 50 kg, you will have to pay from 750 to 800 rubles.

How to DIY

By itself, white cement diluted with water is not used in construction, since such a layer will soon crack after laying. For this reason, a solution with fillers should be prepared. The problem is that ordinary sand for a white mortar will not work, and even seeded sand may contain a small amount of clay impurities that can color the solutions. In order for the use of white cement for finishing to succeed, you should purchase a special filler.

Important! In order not to make a mistake when choosing a filler, take several types of backfill in small quantities for testing. After that, prepare several solutions by hand according to the number of samples for the sample, and you can decide on the choice of filler after the solution has dried, so that the degree of whiteness can be assessed.

Recommendations for proportions: the ratio of the components should be the same as when working with gray cement - 1 to 3 for masonry mortar or concrete for self-leveling floors, and 1 to 5 for leveling plaster. The ratio of water and cement should not be more than a factor of 0.4, i.e. the consistency of the solution should be dense, but well mixed.

Preparation recommendations: White concrete requires 1 measure of cement, 3 measures of sand and 2 to 3 measures of coarse aggregate. If concrete is required for, then use marble chips with a fraction of 1 to 1.5 cm as a filler. After the concrete has obtained branded strength, grind the surface to perfect condition.

Note, that concrete is made only in a clean mixer, on the walls of which there is no old mortar or rust formed.

Application area

White cement is used for various purposes:

1. Production of joint grouts. since the strength indicators are high, white cement is used to make joint grouts.
   

   As a filler, gypsum or crushed chalk is added to the grout. The setting speed of the composition will depend on the type of filler.

2. Making a mixture for masonry mortar. To make the finishing decorative type masonry look more beautiful, a composition is used as a mortar, which is made on the basis of white cement. The consistency of the masonry mortar should be the same as that of conventional mortars, the difference is only in color.
3. Reinforced concrete products (concrete products). White cement is required for steps on the stairs, as well as for railings, tiles and all kinds of architectural forms.
4. Paving slabs and related elements. Paving slabs, concrete rings, curbs and more are made from a solution of cement and sand. Such products must be either completely white or dyed with special dyes.
5. Finishing brick. This is a special type of cladding that is used for wall decoration. Tiles are made from a mortar made on the basis of white cement, without the addition of dyes or with the addition of pigment.
6. Solutions for self-leveling floor. Dry mixes can be made from such cement with the addition of polymers.
   

   After adding water to the mixture, add marble chips or any other decorative filler. The solution should be evenly distributed over the floor, and after drying, sanded and polished.

7. Solution for external finishing. Cement can be used to make dry plaster mixes. The advantage of such compositions over others based on gypsum is high strength and weather resistance.
8. Making sculptures. Cast sculptures are made of white cement, which are planned to be installed in the open air. Such sculptures, unlike plaster products, will last at least 10 years.

Conclusion

Now you have learned about what white cement is, as well as how it can be used in construction. More information can be found in the video.
