How much does a backing brick weigh. Why know the weight of a building

The weight of a solid red brick 250x120x65 formed building codes. Once upon a time, bricks, common for today's construction, were a luxury. Not everyone could afford to build from it.

Fortunately, environmental pure material is available now. Moreover, many subspecies of bricks have been created. But let's take a closer look at the main one - an ordinary solid red brick.

How to set weight parameters

Without knowledge of the mass, such a building unit has nothing to do either in the design or on the construction site. And they set the parameters for the brick according to the developed standards. Though, if and exceptions (not the standard).

The rules are as follows:

1. 25 mm long.
2. 12 mm wide.
3. 65 mm thick.

It is red clay products made to this size that are in great demand.

Classification

Since we consider the usual ceramic look, it is worth saying that the most common type has the following features:

• frost resistance;
• strength;
• impressive strength.

For your information: it is a solid, and not a hollow type of brick that is better in density.

The outer side is made in such a way that during the process of luggage there is optimal adhesion to the cement mortar. Therefore, properly laid out solid brick walls are resistant to temperature changes, do not crumble, and it is quite difficult to disassemble such masonry.

Dimensions according to GOST

Dimensions in the GOST itself: 250x120x65. The values ​​are in millimeters. Sold under the label:

1. M 075.
2. M 100.
3. M 125.
4. M 150.
5. M 175.

With an index of frost resistance up to F50.

For reference: solid bricks normally contain no more than 12 percent of internal voids, hence the impressive mass of each unit.

And the most important thing is the specific weight parameter. GOST 379-95 confirmed that a solid red brick weighs from 3.4 to 3.8 kilograms. This is the norm for a standard size.

Criterias of choice

It is the red type of brick that is chosen because of the following properties:

1. Strength. The brick was invented and tested specifically for impressive loads. Moreover, in masonry, such units do not lose their shape. And the above marking (M) is the degree of strength. In other words, than more number, the higher permissible load for every brick.
2. Frost resistance. Here, hard frosts are not so much terrible as the “frozen-thawed” cycle. And for him there is just another letter of marking. This is "F". Where the number is the number of freeze and thaw cycles.
3. Heat conduction. For living quarters - the most important criterion. Bricks for thermal conductivity are also tested in production, assigning a coefficient, and the lower it is, the better.
4. fire resistance. This is already important in the construction of heating elements or industrial workshops, because fireproof materials are also the peak for exposure to high temperatures.

Red solid brick often goes into masonry for the internal component of the structure, and it is better to build front areas or, for example, furnaces for furnaces from other types.

Advantages and disadvantages

Let's start with the positive:

1. You can master the rough masonry without experience in a few minutes.
2. The service life of a building made according to all standards is superior to wood and cement-based blocks.
3. Ecology. It cannot contain impurities, dyes or additives. Burnt clay does not spoil nature.
4. Soundproof material. Walls made of such material muffle noise.
5. Availability. Compared to clinker, ceramics are almost for nothing.

From imperfect:

1. Deviations in terms of geometry are possible. As well as some other manufacturing defects. But this is all purely individual.
2. If initially the proportions were violated in production or the remainder of limestone was allowed, then the process of destruction cannot be avoided.
3. New masonry may crumble if the strength factor is not calculated.
4. Fresh brick, assembled into a wall, sometimes gives stains. They are called efflorescences. This is a sure sign chemical sludge, and either the production of building materials is dubious, or somewhere near the trouble with the environment.

Judging by the information presented, as such, there are no shortcomings in a solid brick. There are only ordinary cases associated with the negligence and sloppiness of manufacturers. The material itself is ingeniously simple. But calculating the weight when building from such a material is far from trifling.

More about building bricks and its types, see the following video:

The most important characteristic of any building material is its weight. The weight of the brick, you must know when using it in construction and decoration, this will allow you to do everything necessary calculations loads that can be exerted on the base (foundation) of a wall made of bricks.

Brick is a very popular building material, used both for the construction of walls (including load-bearing ones). and for performance of facing works, at finishing of the building.

What are bricks

Before determining the weight of a brick, you need to find out what they are like and how they differ from each other.

Here it should be understood that according to the production technology, bricks are divided into 2 categories:

• Ceramic
• silicate

They are also divided into the following types:

• Facing brick
• solid brick
• hollow brick

It is important to understand that the weight facing brick, differs from the weight of silicate / ceramic brick and weight of a solid brick.

ceramic brick

Ceramic brick - the most standard and very popular type of brick. Ceramic bricks are produced from several types of clay or a mixture thereof, by firing in a kiln. Such a brick has many advantages, including such important ones as the ability to retain heat, the ability to withstand exposure environment, high strength, low price, not a lot of weight, which may not change significantly depending on the technology of its production, and what is very important for many is its environmental friendliness. Living in a house built of such bricks is very comfortable and absolutely safe for your health.

Weight of ceramic brick

The weight of ceramic bricks is about 4 kg. This figure may vary depending on its type, for example, a hollow ceramic brick has many voids inside, which results in a decrease in its weight. The shape and dimensions of these voids depend on the brick manufacturer.

The weight of ceramic brick 250x120x65 (hollow) is 2.5 kg.

The weight of ceramic brick 250x120x65 (solid) is 3.4-3.8 kg.

There are other sizes of ceramic bricks, respectively, having a different weight, for example, one-and-a-half ceramic bricks 250x120x88 mm, with a different structure of internal cavities. Despite the fact that such bricks weigh more than about 1.5 times more than ordinary bricks, you will build much faster, due to the fact that you will lay 378 such bricks per m3, for comparison you would have to put 512 ordinary bricks.

There is also a double brick, it weighs, respectively, 2 times more than usual. Its dimensions are 250x120x103 mm.

One m3 brickwork weighs about 1500-1800 kg.

The specific weight of brickwork 1 m3 depends on the weight of the brick, and varies from 700 to 1800 kg. This parameter must be known when calculating the foundation of the house.

Silicate brick weighs more than 1m3 1800-2000 kg.

silicate brick

silicate brick- follows the ceramic brick and is becoming more and more popular in Lately. Such bricks are produced in autoclaves under the action of overpressure and the addition of steam, as opposed to the production of ceramic bricks in high-temperature kilns. Sand-lime brick contains about 92-94% sand, everything else is lime 3-5% and various additives 1-2% to improve the quality. With this production technology, silicate brick gains high strength, becomes a good sound-heat-insulator, the service life of such a brick increases. The frost resistance of such a brick is guaranteed from 15 to 50 cycles of freezing and thawing.

Weight of silicate brick

The weight of silicate brick depends on its type:

• The weight of 1 hollow one-and-a-half silicate brick 250x120x88 is 3.8-4 kg
• The weight of 1 solid one-and-a-half silicate brick 250x120x88 is 5 kg

Silicate brick produced in accordance with GOST #379-53 will be 250X120X65 mm in size, and can have different degrees of strength: 75, 100, 150. The weight of such one brick is 1.8-3.2 kg.

Silicate brick lends itself well to coloring by adding various dyes to its composition, which makes it possible to obtain this type of brick, of almost any color.

But from silicate brick, you can not build a foundation, because. it is not resistant to moisture, it is impossible to build ovens, because. this will cause it to decompose, and it is quite difficult to plaster it, because. such a brick is very even and smooth, thanks to which it lends itself well to coloring.

The weight of a brick, it turns out, depends on several parameters at once, first of all it is its composition, what it is made of and production technology. If you do not want to go into the details of this issue, but want to know average weight brick, then it is equal to 2.5 kg.

Bulk weight of brick

The volumetric weight of bricks must also be known during construction. Indeed, in fact, big sizes bricks do not guarantee its great weight. Standard ceramic brick 250X120X65 mm weighs 3.5 kg. A standard ceramic brick with 250X120X65 mm voids weighs 2.3 kg.

In this case, the specific gravity is 2600 kg / m3, while the volumetric weight will be 1800 and 1200 kg / m3, respectively.

To select the optimal strength, you need to know volume weight. In order to determine the weight of bricks without taking into account the volume of voids, you need to calculate the specific gravity.

With the characteristic specific gravity bricks are characterized by their strength, because it does not take into account empty cavities, for example, if you take a brick with 3/4 specific gravity, this means that the strength will be reduced by almost 1/4

Brick cladding remains a popular type of finish: it gives the building a presentable look and protects walls well, and the weight of facing bricks does not increase the load on the foundation too much. For facade works hollow blocks are most often used, but there are other options - they should be studied, the load calculated, and then a choice should be made.

silicate facing brick

It is produced by autoclave from a mixture of 10% sand and 90% lime. Today, with the help of volumetric staining with persistent pigments, blocks of almost any color are obtained, allowing you to create a unique facade. Thanks to new technologies, silicate products have become resistant to ultraviolet radiation - therefore, color fastness is high.

Modern samples have increased strength - up to M300, earlier this figure did not exceed M150. The frost resistance has also increased - the front silicate brick is designed for 50 - 75 cycles of freezing and thawing, unlike the ordinary one - this indicator does not exceed 35. Thanks to special additives, the thermal conductivity and water absorption of silicate products are reduced.

The mass is reduced due to voids: the strength of the pressed product allows you to make internal partitions thin, and the voids are more voluminous. The weight of a hollow facing brick, depending on its dimensions, is given in table 1.

Table 1

For finishing works they also use a single full-bodied facing stone (250 x 120 x 65 mm), whose weight is 3.95 kg

Hyper pressed brick

This type of product leads the market finishing materials. Its technology is very simple, and production is established everywhere, so the price and delivery costs are quite affordable.

Brick is made from semi-dry mixtures of cement, lime and gravel. Due high pressure there is an interpenetration of components, which ensures the strength of finished products (minimum M250). Frost resistance is set at least 150 cycles. The peculiarity of hyper-pressed brick cladding is that over time it increases by 40 - 50%. Masonry water absorption is no more than 5% - this is the most best indicator among all types of finishing stones.

The color scale of products is wide, coloring resistant. Due to the relief of the molds, products with different textures are obtained: smooth, like a chipped stone, semi-antique.

According to their properties, hyperpressed products approach natural stone, so they are quite massive. The weight of a single facing brick with standard dimensions- 4.2 kg, a semi-block with dimensions of 250 x 60 x 65 ("American standard") weighs half as much - 2 kg. Bricks "under the stone" are produced in a shortened version: 250 x 90 x 65, weight - 4 kg.

Ceramic facing brick

The manufacturing technology of products is rather complicated: they are made from red clay with additives, most often by plastic molding, subsequent drying at 150 o and high-temperature firing at 800 o. The resulting products have a strength of M150 - M250, its frost resistance - 25 - 50 cycles. Moisture absorption in ceramics - 10%

Products are produced both in solid and hollow versions (air cells increase the heat-technical qualities of the masonry). The surface is smooth, matte, with imitation "under the stone". Apply various ways coloring: volumetric, surface (engobing), glazing. In the latter case, the glaze is applied only on the front side.

Ceramic products for masonry are strictly standardized. The facing brick has the dimensions and weight indicated in Table 2.

table 2

When creating exclusive buildings, ceramic bricks are also popular. handmade: its dimensions are 188 x 88 x 63; weight 1.9 kg.

Clinker facing brick

Clinker stones differ from ordinary ceramics in their increased strength (M400) and hardness, they are suitable not only for wall cladding, but for finishing plinths, window and doorways. Clinker is obtained from special types of clay when high temperatures. Due to the high density, the products almost do not absorb moisture, have excellent frost resistance (150 cycles), but at the same time their thermal conductivity is high.

Product formats are very diverse, they depend on the specific manufacturer. For facing bricks made of clinker, a considerable weight is characteristic, comparable only with the parameters of a hyperpressed counterpart. To reduce the load on the foundation, use hollow clinker. Table 3 introduces the dimensions and weight of some types of clinker facing bricks.

Table 3

The weight of a non-standard clinker product can be determined by multiplying the volume of the block by the density - for solid clinker it is 1900 - 2000 kg / m3.

Brick is an inexpensive, popular, widely available material suitable for almost any construction. Garages, cottages, various agricultural and auxiliary buildings are built from it.

Many craftsmen have long adopted the strength, reliability and versatility of this artificial stone, mastered the skill of brickwork and are able to easily calculate the amount of material needed for the construction. But only few people take into account its weight. And in vain. Knowing how much it weighs, you can correctly calculate the weight of the building and the thickness of its foundation during construction, providing the structure with strength and reliability.

What determines the weight of a brick

Brick ordinary red differs in density and size. These parameters affect its weight.

In terms of density, it happens:

Hollow (through voids are artificially made in it, round or square, their shape and direction may vary depending on the technology and manufacturer).

Solid (it is a monolithic rectangular parallelepiped with a rare presence of technical voids that affect its weight).

Distinguished by size:

Single 250*120*65 mm.

One and a half 250*120*88 mm.

Double 250*120*138mm.

In the manufacture of red ceramic bricks, clay is used, which, after formation, is fired in special kilns at a temperature of about 1000 degrees. Weight finished product may vary slightly depending on the quality of the raw material. For solid bricks, the weight remains practically unchanged, but in the weight of hollow bricks slight fluctuations are allowed, depending on the size and shape of the voids.

How much does a brick weigh

You can find out how much a red brick weighs if you take into account its density and dimensions from the manufacturing plant. Knowing these parameters, you can easily calculate the weight of the future building.

For a full-bodied they will be:

single 3.3-3.6 kg;

one and a half 4.0-4.2 kg;

double 6.6-7.3 kg.

For a hollow (lightweight) brick, they will significantly decrease due to the "holes" in it:

single 2.3-2.5 kg;

one and a half 3.2-3.5 kg;

double 4.5-5.0 kg.

Now it is only worth multiplying this data by the number required material plus the approximate weight of the consumable solution, this will be the approximate weight bearing walls.

Why know the weight of a building

When building, it is always necessary to take into account how much the red brick and used cement mortar. This will help to calculate the mass of load-bearing walls that put pressure on the foundation, and in accordance with this, calculate its strength, strength load-bearing structures and other construction parameters, to avoid excessive settlement, foundation cracks and other troubles.

Often in the construction of buildings, combinations of hollow and solid bricks are used. For example, a solid one is used for the construction of the first floor, as it is more durable, and a hollow one is used for the construction of the second. Similar combinations can significantly lighten the weight of the building, which should be taken into account when laying the foundation.

When building, it is necessary to take into account many various factors. One of important moments, which needs to be calculated before starting construction, this is how much 1 brick weighs from those that you plan to use during construction. The fact is that the total weight of bricks and other building materials important when laying the foundation and basement of the building.

If you do the calculations incorrectly, the foundation may eventually fail and sink under the building, which will lead to such unpleasant consequences as cracks in the walls, etc. In this article, we will talk about how much a brick of various brands weighs and how to calculate its weight, knowing its density.

silicate brick

First, let's figure out how much a silicate brick weighs. It is he who, as a rule, is used for laying walls in most brick buildings, since he has high density and soundproofing.

Depending on what type of brick you use, its weight also changes. Below are approximate numerical weights for each type:

Full bodied:

• Single - 3.7 kg;
• One and a half - up to 5 kg.

Hollow:

• Single - 3.2 kg;
• One and a half - 3.7 - 4.2 kg;
• Double - 5.4 kg.

Facing:

• One and a half - 3.7 - 4.2 kg;
• Double - 5 - 5.8 kg.

ceramic brick

Now let's consider how much a red brick weighs, or, in other words, ceramic, obtained as a result of firing clay. It can also be used for construction, but much more often it is used for cladding buildings.

Full bodied:

Hollow:

• Single - 2.3 - 2.5 kg;
• One and a half - 3 - 3.3 kg;
• Double - 4.6 - 5 kg.

Facing:

• One and a half - 1.32 - 1.6 kg;
• Double - 2.7 - 3.2 kg.

Brick weight calculation

How much does a solid brick weigh, you can calculate, knowing its dimensions and specific gravity. We emphasize once again that such calculations are only suitable for solid bricks. If the brick contains any holes or relief, its weight will be significantly reduced.

For example, you have a brick with a size of 250 * 120 * 65 mm and a density of 1.8 g / cm 3. To calculate its weight, follow these steps:

1. First convert mm to cm (25*12*6.5) as density is given in cm3;
2. Calculate the volume of one brick - multiply the length, width and height (25 * 12 * 6.5 = 1950 cm 3);
3. Then multiply the volume by the density (1950 * 1.8 = 3510 g or 3.510 kg).

Such a calculation is more accurate, however, it does not give you the opportunity to calculate the exact weight of your entire building. The fact is that the dimensions of the bricks in each batch may vary slightly and, accordingly, their weight will change.

In addition, when calculating the weight of the masonry, one should not forget that between the bricks there is building mixture. Its weight can also be calculated, knowing the volume required for the construction of 1 square. m. masonry and the density of the solution. Weight of one cube. m. of cement is about 1300 kg.
