How many bricks in 1 cu. m?

 How many bricks in 1 cu. m?

A good builder first considers and then builds, and a bad one does the opposite. First of all, a tool is prepared and the need for the materials used is calculated. It is important to understand what the building will cost. It is necessary to make the expenditure part of one party, and it was enough. Surplus talk about errors and useless costs, the shortage leads to the risk of disruption of construction time and additional transportation costs. Thus, the estimate provides the conditions for a satisfactory outcome of the project or makes it more unprofitable.

Some aspects when buying

Sellers, as a rule, form the shipment on pallets in the volume of one cubic meter per shipping unit. Buyer should check this. The main thing is not to overpay. The working brick has a standard, well-known form, but different sizes. Market realities are such that some entrepreneurs can offer products without strict adherence to GOST. When accepting a product, at least with the help of a square, the angle between the planes should be estimated, it should be strictly 90 degrees. Defects in production will automatically lead to negative results in terms of the quality of the structure.

Determining the number of possible different methods. The calculated volume of one brick can be multiplied by their total number. Knowing how many there are in a row and the total number of series reduces the solution to the problem to the multiplication of known numbers. It is less time consuming to take a measuring tool and measure the length of the faces in the package. The product of three dimensions will indicate how much space the product occupies; the result must be divided by the volume of one unit. This method is faster, but less accurate.

The number of bricks in one cube

The source element for such a calculation is the definition of the type of work item. The classic red single brick is thermally processed clay in standard form. Dimensions are 250x120x65 mm, where:

  • the largest value is length;
  • average is width;
  • thickness is a smaller value.

Important! The one-and-a-half option for this dimension is 88 mm, double - 138 millimeters.

White silicate brick is made in the same proportions, but it has less weight and, by material quality, less durability. Lightness is convenient for the work of a bricklayer, but weakened indicators at the fracture reduce the overall reliability of the structure, reduce the limits of application. The price is lower, but the quality is worse. To calculate the amount of 1 cu. m masonry matters the average width of the seams and the thickness of the wall. Due to the use of mortar, the amount in a cubic meter upon purchase does not coincide with the number of units used in the construction of the same volume. So in the process you need to make adjustments.

To calculate the number of pieces in a pack you need to know the size of the bricks. For the formation of the application for the purchase of the party need information about what will be the volume of facilities,what method will be stacked. Different wall thicknesses, differences in performance elements must be taken into account. It is necessary to add 5–10% to the estimated rate for all characteristics.


The most popular option at a construction site may be the calculation of the amount of red single brick, which is done by applying standard mathematical rules. A single brick occupies a volume of 1950 centimeters in a cube. Accordingly, the number in cubic meter is 1 cube. m divided by the known volume. Citing cubic centimeters in cubic meters or, conversely, and rounding to an integer when dividing, we get 513 pcs. in cubic meter. Such indicators are used for transportation, but not after laying.

It is considered that the average seam between the bricks in the process of their installation is 1.5 centimeters. If they are bonded with a solution in two planes, as is the case when laying “clamping”, the width of the seam should be added to the standard dimensions in two dimensions. That is, the length and thickness of the "throw" by 1.5 cm. In this case, a single brick with seams will give dimensions of 26.5x12x8 cm, respectively, will need 394 pieces after rounding up. Sometimes the builder wants to know how much a batch of 1,000 or 3,000 bricks will take when laid.In this case, you can apply the mathematical proportion - 394 pcs. in one cubic meter means that 1000 will provide a laying of 2.5 cubic meters, and a batch of 3000 pieces. Satisfy the builder in the construction of the object volume of 7.6 cubic meters. m

Another method of laying the "sprinkling" is applied when the wall is supposed to be plastered. Here, the primary elements of the building are connected only between horizontal rows. The mixture consumption in this case is less, but the laying material will need more. When calculating the volume of the primary element, we add 1.5 cm only along the length and we get 2067 centimeters of cubic per one stacked unit. Per cubic meter will require 484 pieces. Similar methods of calculation are appropriate for other options stacked product.

It should be noted that the size and methods of installation can not only change the need for a solution due to the seams, the average width of the seams in different structural elements may vary. All this should be carefully considered before starting work.


The calculation of the number of half-brown bricks in a cube is not fundamentally different from the previous version, since the difference is only in size, but not in the essence of mathematical operations.Since this standard measures 25x12x8.8 centimeters, the volume is equal to 2640 centimeters in a cube. One cubic meter when you purchase should hold 379 pcs. after rounding up. In the case of conventional laying with horizontal and vertical seams, the faces should be increased by 1.5 centimeters on both sides. So, we get 306 pieces per cubic meter after installation.


The estimated need for a double brick per unit volume is similar. The product on those planes 25x12x13.8 cm occupies a volume of 4140 cubic centimeters. Accordingly, in a cubic meter - 242 pieces. Per cubic meter of masonry using horizontal and vertical joints - 206 units. Fans of using this option in order to save money should take into account that it is not suitable for the construction of foundations and lower floors in terms of permissible load, and is also too weak for serious loads. For the manufacture of foundations, a special chemically protected base brick is sometimes used, having dimensions of 23x11.3x6.5 cm. The results of similar calculations will be as follows: one brick occupies a volume of 1,689.35 cubic meters. cm, so 1 cubic meter on a pallet will hold 592 pieces.Taking into account the seams in the laying of one cube, 452 bricks will be used.

Calculations based on wall thickness

When calculating the total delivery lot, you need to know what the exact cubic capacity of the structure will be in the details, as well as how it will have to be ensured. The laying in one brick gives a wall thickness of 25 centimeters, in two - 51 centimeters. Laying methods of 0.5, 1.5 and 2.5 bricks create thicknesses of 12, 38 and 64 cm, respectively. It is clear that the cubic capacity of a square meter of walls of different thickness will differ significantly. Laying methods, brick sizes and wall thickness change the basic calculations. The initial data before the start of work is conveniently presented in tables.

Material consumption per square meter of masonry

It is more convenient for some bricklayers to count not the number of pieces per laid cubic meter, but how many units will be per square meter of brickwork. In this case, the norm per square meter of surface is calculated taking into account the wall thickness in the presence of seams of a certain size. The number of squares is the basis for assessing total needs.However, in addition, what is at stake above, the builder needs to know for sure and the weight of cement per cubic meter of the structure. The first aspect that influences the consumption of construction mix is ​​the type of brick. For a hollow product solution will require more. The amount of cement in the binding mixture is determined by the strength criteria of the structure and brand of cement. It is considered that when laying one cubic meter of an ordinary (classical) brick, certain volumes of mortar are used.

Larger bricks due to less frequent crosslinking reduce the need for mortar. To calculate the total amount of the mixture, you first need to determine the volume of the building structure. Each element of the construction object must be considered separately, and the results summarized. Cement brands are different, the higher - the more expensive, but the more expensive - the less it is needed to provide the desired strength. The easiest way to calculate the amount of material in the construction of solid walls. The volume of the structure is determined by a simple product of the parties, then, taking into account the method of laying, the amount of brick is determined, as well as the need for a mixture.Cement by brand and quantity must be purchased depending on the proportion in which it will have to be mixed with sand.

Suppose that as a result of the calculations it turned out that 4 cubic meters of mixture would be required for the construction. If a solution with a low grade cement is used, mixed according to the 1: 1 scheme, it means that it will be needed in the amount of 50% of the dry mix, which will be two cubic meters. If the mixture is prepared according to the 1: 3 principle, then 25% is required, in our case - 1 cubic meter. If the proportion is 1: 4, then the cement will be one-fifth, that is, 0.8 cubic meters. It remains to find out how much one standard bag holds, given that it is estimated in kilograms.

Take into account the stock

Masters advise not to buy brick and cement in the exact calculation, but still add 5-10% to the calculated results. This is the so-called rule of various construction circumstances. The experience of the handler or the quality of the products here is not the last. When it comes to consignment, it should be remembered that the process of production, loading and transportation can lead to product defects. An important factor in the purchase is that cement is not sold per cubic meter.A standard bag holds 25 or 50 kilograms. Conversion of cubic meters to kilograms is possible using the density value of the hardener. Usually this indicator is taken as 1300 kg per 1 cubic meter.

For example, 2 cubic meters of cement is 2600 kilograms, 2600: 25 = 104 bags of 25 kilograms each. As with the purchase of bricks, it is advisable to add 5–10% here, it is reasonable to take at least 2,730 kg for the brand of products that will have to be used. Higher strength properties allow a smaller amount to be used. Low strength determines a larger volume; a high grade reduces volume in application, but increases the price of one bag of products. In practice, you need to know that a 10-liter bucket can hold 12 kilograms of sand and 14 kg of cement. Playing with the quality of materials and brick sizes, brand of cement and type of masonry can significantly reduce the overall estimate, as well as critically reduce the strength of the structure.

The components of success are the correct measurements, accurate calculation and qualification of the stacker with the tolerance of the consumption of materials plus 5-10%. Who does not want to overpay, he must be able to confidently use a calculator and simple mathematical operations.The exact estimate is the first thing. Competent purchase and delivery - the second condition. High-quality installation work completes what has been started.
