Weight of red solid brick: weight of density in one pallet

How much does a red brick weigh? How to find out the weight of one brick

The weight of a red brick depends on its density and volume, knowing the density and volume of the material, it is quite easy to calculate the weight.

In order to find out how much a red solid brick weighs, you need:

1. Determine the type of brick, for this you can use its marking, find out the class of average density, and then refer to GOST 530-2007. With a density class of 2.0, the average density is from 1400 kg / m3;
2. Calculate the volume of one product. To do this, multiply the length by the width and by the thickness. The result for a product with dimensions 250x120x65 will be 0.00195 m3;
3. Multiply the result obtained by the average density for the class. As a result, we get the average weight of a red solid brick 250x120x65 - 3.3-3.6 kg.
4. The weight of a hollow brick is calculated using the same formula, but with the addition of the percentage specified in GOST for the voids in the brick body. So the weight of a red brick 250x120x65 with a void of 6% is about 2.7-2.9 kg.

The second, faster option is to use special tables to determine the mass. The weight of the facing brick also depends on the density and size, it can be determined either by calculation or using the table.

How to determine how much a kiln brick weighs? It is best to use table values ​​here.

Weights and measures table

Standard weight and specific gravity of solid and hollow building bricks

We have already said that not only the dimensions of the brick, but also its type will affect the weight of this product. First, consider the weight of solid bricks of different types:

the weight of a red solid brick 250x120x65 mm will be equal to 3.5 to 3.8 kg per one product;

Corpulent single

the weight of a red solid brick 250x120x88 mm will be equal to 4 to 4.3 kg per piece;

Corpulent one and a half

the weight of the double brick will be 6.6 to 7.2 kg per block.

Let's compare these indicators with the weight of hollow bricks of the same dimensions:

the weight of 1 red hollow brick 250x120x65 mm is from 2.3 to 2.5 kg;

Hollow single

the weight of a red hollow brick 250x120x88 mm will be equal to 3 to 3.3 kg;

Corpulent one and a half

the mass of double hollow bricks is from 4.6 to 5 kg per block.

Hollow double

The weight of an ordinary red brick allows you to determine the potential load on the foundation of a building, so this information needs to be known at the design stage of the building.

However, such a calculation is more convenient to calculate not in relation to the weight of one brick, but in relation to the specific weight of the building material per cubic meter of area.

Here the values ​​will be as follows:

• the weight of 1 m3 of red solid brick 250x120x65 mm will be equal from 1693 to 1847 kg;
• the weight of 1 m3 of one and a half red brick will be from 1515 to 1631 kg;
• the weight of 1 m3 of double red brick is from 1597 to 1742 kg.

It would seem that the weight of a single red brick is less than the weight of one and a half and a double, but the total mass of this building material, located on one cubic meter, is higher. What's the matter?

Everything is simple enough. The fact is that one cubic meter of space accommodates a larger number of single bricks - about 513 pieces. As for one-and-a-half bricks, there are only 379 pieces in 1 m3.

The double brick is even smaller due to its large dimensions. On average, 242 pieces are placed on one cubic meter of area. We found out the weight of a red solid brick 250x120x65 per cubic meter.

Let us now consider similar parameters, but for hollow bricks:

• the specific gravity of a red hollow brick 250x120x65 mm per cubic meter will be from 1180 to 1283 kg;
• the weight of 1 m3 of one-and-a-half hollow brick will be from 1137 to 1250 kg;
• the weight of one cubic meter of double hollow brick will be from 970 to 1210 kg.

As for the number of pieces in one cubic meter, this indicator fully corresponds to the number of solid bricks in 1 m3. Bricks are often sold in batches. It is clear that rarely will anyone need to purchase a brick by the piece, so they buy pallets with bricks.

So, the weight of a pallet of solid red brick 250x120x65 mm is from 660 to 1440 kg. At the same time, one pallet can hold from 200 to 400 items.

One pallet of double solid bricks will weigh from 1320 to 1440 kg. The pallet also holds about 200 pieces. We found out the weight of one standard red brick, which is about 3.5 kg. Various supporting structures, foundations and other elements of each building are made from it.

But people use other types of bricks as well, so they need to know about all of their parameters. In addition to standard bricks, there are two more types - facing and refractory. So, the weight of a red facing brick without voids will be from 3.6 to 3.7 kg.

If voids are present, i.e. the brick is hollow, its weight will be from 2.1 to 2.7 kg. One-and-a-half facing brick will have the following parameters:

• the weight of hollow bricks ranges from 2.7 to 3.2 kg;
• the weight of 1 solid red brick is from 4.2 to 6 kg.

The weight of the red brick oven will be from 3.5 to 4 kg. It should be noted that refractory bricks are produced only in full-bodied, i.e. without any voids and holes.

For more information on the weight of the brick, see the video:

Brick structure

Building bricks in masonry require mandatory plastering or cladding with other materials. Since in the GOST, according to which it is produced, the tolerance for the presence of chips on the surface of the product with a depth of up to 10 mm is prescribed.

The sides of the bars are called like this:

• bed - the supporting wide side of the block, located in the same plane with the base of the masonry;
• spoons - a long edge of a brick, in the masonry it retains an upright position, is located at a right angle to the wide edge;
• butt - a short edge, located at right angles to the bed.

Voidness (b) in a given building material denotes how much of the total volume is occupied by voids. It is expressed as a percentage.

Traditional ordinary clay bricks are classified according to several parameters:

• by geometry: normal format, one and a half, double (stone);
• by voidness: brick is solid and hollow, stone is hollow;
• by density, the material is divided into classes;
• by strength, products are subdivided into grades and are designated, for example, M200, M300;
• according to frost resistance, brick is subdivided into grades and is designated F25, F75;
• by heat-shielding characteristics: highly efficient, effective, ineffective.

Dimensions, weight and price

To ensure the convenience of laying the stove, you need to buy products that differ in their configuration and sizes. All this information is contained in table 1.

Table 1 - Dimensions of oven bricks, taking into account their shape

The ladder has the standard dimensions of the kiln brick. It comes in the form of a parallelepiped. Its largest facet is called the bed, the middle one is indicated by a spoon, and the smallest is indicated by a poke. In the end wedge, the poke has a narrowed shape, and in the rib wedge, the spoon is narrow. These two types are used for curly masonry. In addition to standard products, fireclay plates can be purchased. Their dimensions are similar to those of the firebox, which they should cover. As a rule, such products are sold in sizes 460 x 230 x 75 mm and 600 x 230 x 90 mm.

The video tells how much the kiln brick weighs:

Since fireclay can store thermal energy, it can be used not only for the construction of a firebox, but also for the entire furnace structure. This solution is very beneficial in terms of decoration, because the straw-golden hue of clay bricks allows you to create a visual effect of warmth and comfort in the house.

A wide range of shapes and sizes of fireclay bricks allow it to be used for laying out both straight and trapezoidal, vaulted surfaces. Another advantage of this material is its pliability when using a power tool. Such material is considered environmentally friendly, therefore it is actively used when laying a fireplace and stove.

Kiln weight refers to a standard value that affects the total weight of all material on the pallet. Knowing its value, it is very easy to determine the load that will be applied to the foundation of the structure being built, what is the mass of 1 m3 of material, what capacity the transport must have in order to deliver it.

If you use a red stove-top corpulent material, then its weight will be:

• 250x120x65mm - 4.2 kg
• 228x115x64mm - 3.6-3.8 kg

When using refractory red brick, the parameters of its weight are:

• 250x123x65mm - 3.4 kg
• 230х113х65mm - 2.9 kg

Now let's dwell on the cost of products.

It also depends on what material was used in the manufacture, the attack, its dimensions:

1. A red front brick costs 60 rubles apiece.
2. A chipped red face brick costs 70 rubles.
3. Front brown brick costs 75 rubles.
4. Refractory bricks will cost 85-110 rubles.

The construction of a stove is a very responsible process, since it has to be dealt with with fire. When choosing a material for its masonry, it is necessary to take into account a number of nuances: material, weight, dimensions, properties. Only the right material and high-quality masonry will provide you with comfort and coziness. You may also find useful information on how to prepare a mortar for laying a stove. The proportions for the preparation of clay mortar for the masonry of the stove are described here.

Silicate brick

In fact, silicate bricks are bars made of silicate autoclaved concrete, having the shape and size of a brick. It consists of approximately 90% lime, 10% sand and a small proportion of additives. Its advantage in comparison with ceramic is its low cost, the ability to provide a variety of shades. Disadvantages: sand-lime brick is heavy, not very strong, not waterproof, easily conducts heat. Therefore, it is inferior to ceramic bricks in its versatility and is used only in the laying of walls and partitions, but cannot be used in foundations, plinths, stoves, fireplaces, pipes and other critical structures.

The properties of silicate bricks are regulated by GOST 379-79 “Silicate bricks and stones. Technical conditions ". Its main characteristics:

1. strength grade - М125, М150;
2. frost resistance grade - F15, F25, F35;
3. thermal conductivity - 0.38–0.70 W / m ° С.

Requirements for dimensions, quality, geometry and appearance of silicate bricks are similar to those for ceramic bricks.

The ratio of silicate and ceramic bricks is 15 and 85%, respectively. The only manufacturer of silicate bricks in our region is CJSC Pavlovsky Plant of Building Materials. The modern assortment of the enterprise consists of both traditional white solid silicate bricks and new types of products (silicate hollow bricks, silicate wall hollow blocks). Since 1998, the company has been producing textured bricks "Antik" (with the effect of a stone wall of an old castle). Since 1999 - volumetric colored bricks and bricks with fillers that improve its thermal insulation properties. In July 2003, ZAO Pavlovsky Zavod SM produced the first batch of silicate hollow bricks.Among the main advantages of the new product are the weight of the product (thanks to 11 blind holes, the brick weighs only 2.5 kg) and low thermal conductivity.

Examples of modern silicate bricks produced by the Pavlovsk plant SM:

Weight of 1 m3 of brickwork

The quality factor of brickwork depends on the type of building material and the correctness of its laying.

To determine the quantity bricks per cube of masonry, it is necessary to take into account the volume indicators of the entire structure. In addition, the consumption of material is determined by the typical characteristics of the brick and the thickness of the joints.

The raw materials used in the manufacture and the processing conditions determine the dimensions (see Standard size of red brick) and the specific gravity of the brick (see Weight of sand-lime brick). With regard to brickwork, this parameter also depends on the number of seams, the mass of the mortar used and the type of masonry. Thus, the specific weight of brickwork is in the range of 1400-1990 kg / m3. The next value required for the calculation is the volumetric weight (unlike the previous one, the presence of voids and pores is taken into account).

The mass of the masonry wall must be calculated in order to determine the optimal and boundary loads on the base. This value predetermines not only the type of foundation to be built and its material, but also many other design and design parameters.

Today, brickwork remains the most common type of wall. It is characterized by stability and strength, along with this, it has a decent mass, which affects the foundation of the building.

The most demanded material in this case is red brick, the standard dimensions of which in millimeters are as follows: 250x120x65, weight - about 4 kilograms. Rough counting takes place because each brick has structural voids, which are allowed by the standards, but their number is not constant. That is why it is more expedient for calculations to take the weight of 1 m3 of brickwork, and not one brick.

When designing any structure, many nuances must be taken into account. In order to fully compose a picture of the upcoming loads on the building, plan the base and correct the dimensions of the building, you need to familiarize yourself with the technical characteristics of the material - brick.

Through these parameters, it is possible to give an objective assessment of the bearing capacity and strength of the future building, therefore, when designing, they must be taken into account.

Quite often, the decent weight of a brick wall prevents the use of this material. This is not possible if the ground under the base of the building is unstable, moist or mobile. In such cases, alternative materials are used that have an advantage over traditional red bricks in weight:

• expanded clay concrete blocks;
• foam concrete;
• gazosipikate;
• cinder blocks.

Indeed, all of the above materials allow you to build fairly practical and lightweight buildings in less time and with some savings. Nevertheless, they are significantly inferior in strength to classic bricks, and some of them shrink during operation.

Do not forget that the weight of the masonry cube can be affected by the reinforcement of the walls or individual components of the supporting structures. Sometimes the mass of mortar and reinforcing mesh is not inferior to the weight of the entire wall (see.Cement consumption for brickwork)

It is customary to call a brick wall material, which is obtained as a result of firing various types of raw materials. For ceramics, these are separate types of clays, and for silicate products - sand, lime and water. Each of the considered types of wall products has its own characteristics, which means that their weight per unit volume (in our case, a cubic meter) will be unequal.

The mass of each individual brick will depend not only on the raw material composition, this indicator is also influenced by the production technology (firing temperature, the presence of voids, etc.). It should be noted that each wall material has its own tolerances for individual characteristics, including weight.

In custody

Summing up, it makes sense to recall several important rules when choosing and purchasing such a building material for certain needs.

Facing, as well as oven bricks should not have obvious irregularities, chips and cracks. Moreover, this rule does not apply to an ordinary foundation

When choosing, you should pay attention to the shape. No flaws are allowed in the facing

The color should not be too light - this may mean that the brick is not "baked", and this fact indicates its low quality. The same applies to dark spots on the surface or on a cut - a burned-out product also loses its strength.

Almost finished facing brick fence

You should not buy the front material in open markets and sites - the ingress of precipitation on its working surfaces destroys the structure. This happens due to the insecurity of these surfaces. After all, only its front parts are adapted to the weather.

The sound of any product when struck with a hammer should be sonorous - this indicates that there are no violations of manufacturing technology. Also, before purchasing, it makes sense to consult with those who have recently completed such construction. From their experience, you can understand what the disadvantages and advantages of the material of a particular manufacturer.

As for the oven brick, its choice is especially important. You should not buy cheap products of low brands. The most acceptable are M-250 and M-500. Such material will allow the stove or fireplace to last the longest, while ensuring normal heat exchange in the room - the stove will not cool down quickly.

And the facing brick may look like this

And the most important thing. Each type is designed for its own field of application. And due to the fact, no matter how convenient a hollow brick is in masonry and operation, it cannot be used on supporting structures. It may simply not be able to withstand the load. The result is the collapse of the wall.

And finally, a short video on the topic.

Varieties and classification of red bricks

Red brick is a fairly broad concept, so it is impossible to unequivocally answer the question - how much does a red brick weigh? Let's first consider all of its varieties, then to tell in more detail about the weight and dimensions of each brick.

So, here is the main classification of red bricks:

standard red brick;

Standard red

facing brick;

Facing

red refractory brick.

Refractory

Ordinary red brick is used for laying walls in buildings.

Wall masonry

In addition, the partitions between rooms are also made of this brick. Facing brick is intended for finishing the facades of buildings, so it costs significantly more than ordinary standard bricks.

Facade finishing

As for refractory bricks, they are used in the manufacture of chimneys, stoves and other structures that have direct contact with an open fire.

Furnace finishing

About colors

Why is it red? Basically, it all depends on what kind of clay is used. After firing, the clay sets the color of the brick. Red is perhaps a classic in every way.

What is the size of the basement brick, as well as how it looks in the photo, you can find out from this article.

Clay can contain iron oxide, which affects the color of the future material. How do you get a red brick? Several stages are carried out:

• the material is crushed and then mixed;
• add components and shape the product;
• dried;
• fired.

From which brick it is better to fold a fireplace stove, you can find out by reading this article.

The mass of clay is crushed and all excess impurities are removed. Then the components are crushed almost into dust, the mixture becomes homogeneous. After adding all the necessary components to the composition, excess moisture is removed and given shape

Evaporation of moisture occurs evenly from all sides, it is very important to achieve this. Otherwise, the brick will change shape and crack.

And the finishing activities are firing. 800 degrees - this is the temperature used for firing. The components are able to bond well.

Ceramic brick reviews and other characterizing data can be found in this article.

If it is done correctly, then it can be determined by some parameters. If you hit it, then the sound should be sonorous, clear and subtle. If the material has been burnt, then the core will be black, the edges will be burnt. Such a brick can only be used when laying the foundation.

The video tells about the weight of a red solid brick:

Brick density

The strength of a ceramic building material depends on its density. For a full-bodied bar, no more than 13% of internal cavities are allowed. With a size of 250x120x65, the weight is ideally 3.501 kg. Taking into account production tolerances and fluctuations in humidity, the mass of one piece is in the range of 3.5-3.8 kg. Bulk density will be 1700-1900 kg / m3. In practice, there is a block of 250x120x65 mm (full-bodied, red) from 3.2 to 4.1 kg.

The hollow analogue has a density in the range of 1200-1500 kg / m3 due to internal cavities in the form of slots or cylinders. This increases its thermal insulation and soundproofing properties, but prohibits its use in critical structures. The mass of one piece of NF is 2.3-2.6 kg. When calculating the cost of a hollow brick partition, it should be taken into account that more mortar is required for its laying, which goes into the holes.

To take into account the load on the ground, the following values ​​of the mass of a full-bodied bar are taken: 4-4.3 weighs one and a half, double - 6.6-7.2 kg. Sound absorption indicators of standard products must comply with SNiP 23-03-2003: a half-brick wall will reduce the noise level by 47 dB, and in 2 pieces - by 60 dB. The pressure that the product can withstand is indicated in its brand - from M75 to M300. An increase in the number indicates an increase in strength and price per piece.

Nuances when buying

1 m3 of solid elements contains 500 pieces. For masonry of the same volume, only 400 bars of 250x120x65 are required, since ¼ will be occupied by mortar joints. The weight of the ceramic material will be a little more than 1.4 tons. Another 10-15% can be purchased in stock. The price for a single solid brick is in the range of 6.85-9.3 rubles per piece.

When performing large amounts of work, full-bodied elements of double or one and a half size are used. The block, upon self-examination, is considered to be qualitatively burnt, if its geometry is not violated, when struck on the weight, the sound turns out to be sonorous. The signs of marriage are a pale color combined with a dull sound.

If detailed information is required, which is used by professional designers and builders to take into account complex individual conditions, the use of instrumental control methods, then they turn to the following regulatory framework:

• GOST 530-95;
• GOST 530-2007;
• GOST 530-2012;
• GOST 7025-91;
• GOST 7484-78 (1987);
• GOST 8426-75.

These standards will allow you to select the parameters of the brick as accurately as possible, taking into account the operating conditions of the structure.

How many bricks are in 1 m2 of masonry: necessary parameters, options for calculating the required amount

It is possible to determine how many bricks are in 1 m² of masonry under certain conditions, on which the desired figure depends.

Therefore, before tackling the calculations, you should decide on the design features of the barrier being erected. The calculation itself will not cause any particular difficulties.

The number of bricks in 1 m² of masonry walls and partitions is the basis for determining the need for ceramite for the entire volume of construction.

note

When it comes time to plan the procurement of materials for the construction of summer cottages, their characteristics are usually already known: if it is a ceramite fence or an internal partition of a room, the masonry will be half a brick, a household shed is made thick as a whole block, and for the outer wall of a residential building no less than in one and a half ceramite. Depending on the purpose, the following main types of the main element of the masonry are distinguished:

1. Red brick is the most durable, it is used in the construction of load-bearing structures and in terms of volume it can be single, one and a half, double.
2. White silicate block is used for non-critical structures: internal partitions and gazebos, to give the facade an attractive look. This kind in the form of a double volume is not released.
3. Facing ceramite is used to decorate individual structures of architectural objects, and can be single in size with deviations in one direction or another.

To determine how many bricks are in 1 m² of masonry, one must take into account the factors that affect the desired result: the first is the thickness of the walls. It was mentioned above, measured by the length of standard ceramite: ½ part, in a whole block, one and a half, two or more bricks.

The thickness of the mortar joints between the individual elements in the masonry is the third condition for the successful solution of the problem. In the full volume of the wall, approximately one fourth of the gaps are accounted for.

Dimensions of bricks and gaps

There is a state standard - GOST 530–2012 Ceramic bricks and stones, where the nominal dimensions of products and their designations are given. Ceramites are in the greatest demand:

The inter-brick space is filled with cement mortar, the average joint size is taken as 1 cm.Standards for the thickness of brickwork, taking into account the filling of the gaps:

Calculation of the number of ceramites

Obviously, in one square meter of masonry of 1.5 bricks, the number of elements will be greater than with a wall thickness of one length of ceramite.

Therefore, several calculations are performed if the structure will include partitions with different characteristics, including the shape of individual blocks.

For example, you can calculate how many one and a half bricks in 1 m² of masonry in one ceramite. Sequencing:

1. The size of the one-and-a-half element is fixed - 250x120x88 and the wall thickness - 250 mm.
2. Along the length of one meter, taking into account the filling of the seams, (1000/260) * 2 = 7.69 pieces are placed.
3. The number of blocks in height is 1000/98 = 10.20. Here it is not multiplied by 2 - this was taken into account by the previous action.
4. The desired result is 7.69 * 10.20 = 78 pcs.

Alternative way

It is based on determining the surface area of ​​a single masonry element and further shifting towards establishing the quantity depending on the wall thickness. The initial data remains the same as in the previous calculation. The algorithm of actions is as follows:

1. The area of ​​the lateral surface of one element is determined as 0.26 * 0.098 = 0.02548 m².
2. For a half-brick wall, the number of blocks will be 1 / 0.02548 = 39 pieces.
3. The required value according to the condition of the problem - the number of ceramites in 1 m² of brickwork with a thickness of brick will be 39 * 2 = 78 pcs.

As you can see from the result, both methods gave the same answer.To simplify the use of data when determining the need for the purchase of materials, special tables are compiled, in which quantitative indicators are summarized for all options for ceramite masonry.

Table for determining the number of blocks in 1 m² of partitions

Using the table is simple: choose a value suitable for the conditions of the brickwork and multiply by the calculated area of ​​the walls to be built with a given thickness. When determining the volume of the purchase, it is necessary to take into account that the amount of scrap in the purchased ceramite reaches 5% of the total number of bricks.

Specifications

The standard defines strength grades, frost resistance and density class. Strength grades represent the load that a material can bear. It is easy to decipher this value. The number that follows the letter "M" is the number of kilograms per square centimeter that the material can withstand without destruction. Example: M150 means that ceramic bricks of this batch will withstand a load of 150 kg / cm².

Strength and frost resistance grades for ceramic stone and bricks are indicated.

Frost resistance is indicated by the letter F and a number. The figure shows the number of freeze / thaw cycles that do not change characteristics and appearance. For example F50 - 50 frost and defrost cycles. For internal partitions in heated buildings, frost resistance can be taken low - a positive temperature will still be maintained.

Thermal conductivity and coefficient of thermal resistance

The density class corresponds to the average density of the material, but the energy efficiency of the material also depends on the density. The lower the density, the better the thermal insulation properties. But it will not be possible to significantly reduce the density for external walls. They must carry a certain level of stress. Therefore, in recent years, a brick house has been made with insulation.

The ratio of the average density of the product and the density class

How to work with the last two tables? The density class is indicated in the marking. By this characteristic, you can find out the mass of a ceramic brick cube. It is listed in the first table. The second table helps to compare the density of the material and the coefficient of thermal conductivity of masonry from it. For example, the density class of ceramic bricks is specified as 1.0. This means that the cube should weigh 810-1000 kg, and the masonry on a minimum layer of glue after drying will have a thermal conductivity coefficient of 0.20-0.24 W / (m * ° C).

Groups of ceramic bricks and blocks according to the thermal characteristics of masonry (with a minimum amount of mortar)

It is worth saying that according to modern standards, none of the types of bricks gives the necessary thermal resistance. Unless the thickness of the wall will be more than a meter.

Masonry made of ceramic bricks of one and a half or two bricks does not meet modern requirements for thermal conductivity of external walls

In this case, a hollow brick or a building ceramic block wins, since they have the best thermal conductivity characteristics. The wall will be a couple of tens of centimeters already - not 147 cm, for example, but only 105. So, in any case, it is worth considering additional insulation of the outer walls.

Ceramic brick weight

The weight of ceramic bricks depends on the density and the presence / number of voids. The exact figure is recognized in the accompanying documents, and then, the spread within one batch is up to 10%.

The characteristics indicate the weight of different types of bricks: masonry, finishing, with and without voids

Using the old terminology, the approximate weight of ceramic bricks will be as follows:

• Single (type 1 NF, size 250 * 120 * 65 mm):
  • corpulent (private, masonry, construction) 3.3-3.6 kg / piece;
  • worker (private, masonry) hollow - 2.3-2.5 kg / piece;
  • facing (front, finishing) hollow - 1.32-1.6 kg / pc.
• One and a half has a mass (type 1.4 NF, dimensions 250 * 120 * 88 mm):
  • full-bodied private - 4.0-4.3 kg / piece;
  • hollow private - 3.0-3.3 kg / piece;
  • facial hollow - 2.7-3.2 kg / pc.
• Double weighs (1.8 NF 288 * 138 * 88 mm.):
  • ordinary corpulent - 6.6-7.2 kg / piece;
  • ordinary hollow - 4.6-5.0 kg / pc.

Comparison of the characteristics of ceramic bricks - hollow, different density, solid

We will give an approximate weight, since the density and number of voids for each plant can differ significantly. The number of voids is not regulated, so the finishing materials can be lightweight.

Density of ceramic bricks

Physical and chemical properties and technical parameters of the product largely depend on the internal structure. One of the indicators that clearly characterize the named qualities of ceramic bricks is density. It directly depends on the fractional composition of raw materials, the variety and porosity of building bricks.

Data on the density and some other indicators of ceramic bricks are given in the table:

The density of ceramic bricks determines its class, which is indicated by a numerical code ranging from 0.8 to 2.4. The figure given indicates the weight of one cubic meter of building material, expressed in tons. In total, there are six classes of products, the introduction of this indicator greatly simplifies accounting and office work in the construction industry.

Knowledge of such an indicator as density is necessary for carrying out design and design work and determining the ultimate loads on the foundations and load-bearing elements of the building. The homogeneous structure of the brick provides it, on the one hand, with high mechanical strength, and on the other hand, with low thermal insulation properties. In the case of using monolithic bricks for the construction of a building, additional measures should be taken to insulate the walls.
