A good builder first considers, and then builds, but bad does the opposite. The first thing is preparing a tool and the need for the need for materials used. It is important to understand what the structure will cost. It is necessary to make the consuming part to be one party, and it was enough. Surplus talk about errors and useless costs, the shortage leads to risk of disrupting the construction of construction and additional transport costs. Thus, the estimation provides conditions for a satisfactory result of the project or makes it more unprofitable.
Some aspects when buying
Sellers tend to form shipment on pallets in the volume of one cubic meter on the shipment unit. The buyer should check it. The main thing is not to overpay. The working brick has a standard, well-known form, but different sizes. Market realities such that some entrepreneurs can offer products without accurate advent of GOST. Taking goods, at least with the help of a square, you should estimate the angle between the planes, it should be strictly 90 degrees. Production defects will automatically lead to negative results in the sense of the quality of the structure.
Determination of quantity is possible by different methods. You can calculated the volume of one brick multiplied by their total number. Knowledge of how many of them in the series and total number of rows reduces the solution to the multiplication of known numbers. Less laborious to take the measuring instrument and measure the length of the faces in the package. The product of three dimensions will indicate which space it takes the goods, the result obtained must be divided into the volume of one unit. This method is faster, but less accurate.
The number of bricks in one Cuba
The source element for this calculation is to determine the type of work. Classic red single brick is a thermally processed clay in standard form. Dimensions are 250x120x65 mm, where:
- The greatest value is the length;
- The average is width;
- Thickness – Less Value.
Important! The one-and-a-half version of this measurement has 88 mm, double – 138 millimeters.
White silicate brick is manufactured in the same proportions, but has a smaller weight and quality of material – less strength. Easy is convenient for the work of the mason, but weakened performance indicators reduce the overall reliability of the design, reduce the limits of application. The price is smaller, but also quality – worse. To calculate the number of 1 cube. m masonry matters average width of seams and wall thickness. Due to the use of a mortar, the number in the cubic meter does not coincide with the number of units used when the same volume is erected. So in the process you need to make adjustments.
To calculate the number of pieces in a pack you want to know the size of the brick. To form a bid to purchase a batch, you need information about what the volume of the structure will be the method. Various wall thickness, the differences in execution should be taken into account. To the settlement rate in all characteristics it is necessary to add 5-10%.
The most popular option at the construction site may be the calculation of the amount of red single bricks, which is done by applying standard mathematical rules. One single brick occupies a capacity of 1950 centimeters in Cuba. Accordingly, the number in the cubic meter is 1 cube. m, divided into a well-known volume. Lowning cubic centimeters in cubic meters or, on the contrary, and rounding up to an integer when dividing, we get 513 pcs. in the meter cubic. Such indicators are used for transportation, but not after laying.
It is believed that the middle seam between the bricks in the process of their installation is 1.5 centimeters. If they are binding to a solution in two planes, as it happens when laying “Lettering”, to standard sizes on two dimensions you need to add a width of the seam. That is, for the length and thickness “throw” by 1.5 cm. In this case, a single brick with seams will give the dimensions of 26.5x12x8 cm, respectively, it will take 394 pieces after rounding to the biggest. Sometimes the builder wants to know which volume in the laid form will take a 1000 or 3000 bricks party. In this case, you can apply a mathematical proportion – 394 pcs. In one cubic meter mean that 1000 will provide a 2.5 cubic laying, and the party is 3000 pcs. Satisfy the builder when building a 7.6 cubic object. M.
Other method of laying “Rizyk” is used when the wall suggests plastering. Here the primary elements of the construction are associated only between horizontal rows. The mixture consumption in this case is less, but the laying material will be required more. When calculating the volume of the primary element, add 1.5 cm only in length and get 2067 centimeters of cubic to one fitted unit. Cube meter will need 484 pieces. Similar calculations are appropriate for other options for fitted products.
It should be borne in mind that the size and methods of laying can not only change the need for a solution due to seams, the average width of the seams in different design elements may vary. All this should be carefully taken into account before the start of work.
The calculation of the number of one-time bricks in Cuba is not fundamentally different from the previous version, since the difference lies only in size, but not in the essence of mathematical actions. Since this standard has dimensions of 25x12x8,8 centimeters, the volume is 2640 centimeters in Cuba. One cubic meter when buying should accommodate 379 pieces. after rounding to the big side. With normal stacking with horizontal and vertical seams, it is necessary to increase by 1.5 centimeters on two sides. So, we get 306 pieces in a cubic meter after laying.
Estimation of double brick needs per unit volume is similar. The product for those planes 25x12x13.8 cm occupies 4140 cubic centimeters. Accordingly, in the cubic meter – 242 pieces. On the cubometer of masonry using horizontal and vertical seams – 206 units. Lovers use this option to save money should take into account that on a permissible load, it is not suitable for the construction of foundations and lower floors, as well as too weak for serious loads. For the manufacture of foundations sometimes use a special chemically protected base brick, having dimensions 23×11,3×6.5 cm. The results of similar calculations will be as follows: One brick occupies a volume of 1689.35 cube. cm, so 1 cubic meter on the pallet is welded 592 pieces. Taking into account the seams in the laying of one cube will be used 452 bricks.
Calculations based on wall thickness
Holding a common batch of delivery, you need to know what the exact cube of the structure in the details will be, as well as in which methods it will have to ensure. Masonry in one brick gives the wall thickness of 25 centimeters, in two – 51 centimeter. Methods of laying at 0.5, 1.5 and 2.5 bricks create wall thickness at 12, 38 and 64 cm, respectively. It is clear that the cubure of the square meter of walls of various thicknesses will differ significantly. Masonry methods, brick size and wall thickness make changes to basic calculations. The initial data before starting work is convenient to submit in the tables.

Material consumption per square meter masonry
Some bricklayers are more convenient to consider not the number of pieces in the laid cubic meter, and how many units will be in a square meter of brickwork. In this case, the norm per square meter of the surface is calculated, taking into account the thickness of the wall in the presence of seams of a certain size. Number of squares – base for assessing common needs. However, in addition, what is the question above, the builder needs to know exactly the weight of cement on the cubic meter of the structure. The first aspect affecting the consumption of the construction mixture – the view of the brick. For the hollow product of the solution will be required more. The amount of cement in the binding mixture is determined by the criteria for the strength of the structure and the cement brand. It is believed that when laying one cubic meter of ordinary (classical) bricks use certain amounts of solution.

Larger bricks due to less frequent stitching reduce solution requirements. To calculate the total amount of the mixture, first need to determine the volume of construction design. Each element of the construction object should be considered separately, and the results are summarized. Cement marks are different, the higher – the more expensive, but the more expensive – the less it is necessary to ensure the necessary strength. Most simple to calculate the amount of material when erecting solid walls. The larger of the parties is determined by the volume of the structure, then taking into account the laying method, the amount of brick is determined, as well as the need for mixtures. Cement on the brand and quantity must be purchased depending on which proportion to the sand it will have to mix it.
Suppose that as a result of the calculations it turned out that 4 cubic meters of the mixture will be required for construction. If a solution with a low cement brand is used, mixed according to the 1: 1 scheme, it means that it will be required in the amount of 50% dry mix, which will be two cubic meters. If the mixture is prepared according to the 1: 3 principle, then 25% will be required, in our case – 1 cubic meter. If the proportion is 1: 4, it means that cement will be one fifth part, that is, 0.8 cubic meters. It remains to find out how much one standard bag contains the fact that it is estimated in kilograms.
We take into account the reserve
Masters advise to buy brick and cement not in exact calculation, but still add 5-10% to the calculated results. This is the so-called rule of various construction circumstances. Experience of the stacker or product quality here have not recent. When it comes to a batch of goods, it should be remembered that the production process, loading and transportation can lead to product defects. An important circumstance when buying is that cement is not sold on cubic meters. Standard bag holds 25 or 50 kilograms. Cubic meter translation in kilograms is possible using a hardener density. Usually this indicator is accepted as 1300 kg per 1 cubic meter.
For example, 2 cubic meters of cement are 2,600 kilograms, 2600: 25 = 104 bags of 25 kilograms. As with the purchase of bricks, it is advisable to add 5-10%, it is reasonable to take at least 2730 kg for the brand of products that will have to use. Higher performance allow you to use less. Low strength determines the greater volume, high brand reduces the volume in application, but increases the price of one bag of products. In practice, it is necessary to know that a bucket of 10 liters can accommodate 12 kilograms of sand and 14 kg of cement. The game with the quality of materials and the size of the brick, the cement brand and the type of masonry can significantly reduce the overall estimate, as well as critically reduce the strength of the structure.
Successional components are the correct measurements, accurate calculation and qualifications of the stacker with the allowance of the consumption of materials plus 5-10%. Who does not want to overpay, he should be able to confidently use the calculator and simple mathematical actions. Accurate estimate – the first thing. Competent purchase and delivery – the second condition. High-quality laying work completes.
