# How many bricks in 1 cube m?

A good builder first counts and then builds, and a bad builder does the opposite. The first step is to prepare the tool and calculate the need for the materials used. It is important to understand what the structure will cost. It is necessary to make sure that the expenditure part was one batch, and it was enough. Excesses indicate errors and unnecessary costs; a shortage leads to a risk of failure to meet the construction deadlines and additional transport costs. Thus, the estimate provides the conditions for a satisfactory result of the project or makes it more unprofitable.

## Some aspects when buying

Sellers, as a rule, form shipping on pallets in the amount of one cubic meter per shipping unit. The buyer should verify this. The main thing is not to overpay. The working brick has a standard, well-known shape, but different sizes. Market realities are such that some entrepreneurs may offer products without exact compliance with GOST. Accepting goods, at least with the help of a square, the angle between the planes should be estimated, it should be strictly 90 degrees. Production defects will automatically lead to negative results in terms of the quality of the structure.

**Quantity determination is possible by different methods.** You can multiply the calculated volume of one brick by their total number. Knowing how many of them are in a row and the total number of rows reduces the solution of the problem to the multiplication of known numbers. It’s less time consuming to take a measuring tool and measure the length of the faces in the bag. The product of three measurements will indicate how much space the product occupies, the result should be divided by the volume of one unit. This method is faster, but less accurate.

## The number of bricks in one cube

The initial element for such a calculation is the determination of the type of workpiece. Classic red single brick is a heat-treated clay in a standard form. **Dimensions are 250x120x65 mm, where:**

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

Important! One and a half options for this measurement have 88 mm, double - 138 mm.

White silicate brick is made in the same proportions, but has less weight and lower strength in the quality of the material. Lightness is convenient for a bricklayer, but weakened fracture indicators 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 cubic meter. m masonry matters the average width of the joints and wall thickness. Due to the use of mortar, the amount in cubic meters 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 dimensions of the brick. For the formation of an application for the purchase of a batch, information is needed on how much the structure will be, what method will be laid. Different wall thicknesses, differences in design elements must be taken into account. 5–10% must be added to the calculated norm for all characteristics.

### Single

The most popular option at a construction site can be the calculation of the amount of red single brick, which is done by applying standard mathematical rules. One single brick occupies a volume of 1950 centimeters per cube. Accordingly, the number in a cubic meter is 1 cube. m divided by a known volume. Bringing cubic centimeters to 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 installation.

**It is generally accepted that the average seam between the bricks during their installation is 1.5 centimeters.** If they are bonded with the solution in two planes, as happens when laying “clamp”, the width of the seam must be added to the standard dimensions in two dimensions. That is, “throw” 1.5 cm to the length and thickness. In this case, a single brick with seams will give a size of 26.5x12x8 cm, respectively, 394 pieces will be required after rounding up. Sometimes the builder wants to know how much when stacked it will take a batch of 1000 or 3000 bricks. 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 pcs. will satisfy the builder when building an object with a volume of 7.6 cubic meters m

Another “back-to-back” laying method is used when the wall is supposed to be plastered. Here, the primary elements of the building are connected only between horizontal rows. The consumption of the mixture 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 in length and we get 2067 cubic centimeters per one stackable unit. Per cubic meter, 484 pieces are required. Similar methods of calculation are relevant for other variants of the stacked product.

It should be borne in mind that the dimensions and laying methods can not only change the need for a solution due to seams, the average width of seams in different structural elements can vary. All this must be carefully considered before starting work.

### One and a half

The calculation of the number of one and a half bricks in a cube does not fundamentally differ 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 per cube. One cubic meter at the time of purchase should hold 379 pcs. after rounding up. For normal styling with horizontal and vertical seams, the edges need to be increased by 1.5 centimeters on both sides. So, we get 306 pieces per cubic meter after stacking.

### Double

An assessment of the need for 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. 206 units per cubic meter of masonry using horizontal and vertical joints. Fans of using this option in order to save money should take into account that for the permissible load it is not suitable for the construction of foundations and lower floors, and is also too weak for serious loads. For the manufacture of foundations, sometimes they use a special chemically protected basement brick, measuring 23x11.3x6.5 cm. The results of similar calculations will be as follows: one brick occupies a volume of 1689.35 cubic meters. cm, so 1 cubic meter on a pallet will accommodate 592 pieces. Given the seams in the laying of one cube, 452 bricks will be used.

## Calculations based on wall thickness

When calculating the total batch of supplies, you need to know what will be the exact cubic capacity of the structure in detail, as well as in what ways it will have to be provided. Masonry in one brick gives a wall thickness of 25 centimeters, in two - 51 centimeters. Laying methods in 0.5, 1.5 and 2.5 bricks create wall thicknesses of 12, 38 and 64 cm, respectively. It is clear that the cubic meter per square meter of walls of different thicknesses will differ significantly. Masonry methods, brick sizes and wall thicknesses make changes to the basic calculations. It is convenient to present the initial data before work in tables.

Table 1. The number of bricks in one cubic meter

Type of brick | In the package (pieces) | In a masonry with 2 seams (pieces) |

single | 513 | 394 |

one and a half | 379 | 306 |

double | 242 | 206 |

## Consumption of materials per square meter of masonry

It is more convenient for some masons not to count the number of pieces in a cubic meter laid, but how many units will be in a square meter of brickwork. In this case, the norm per square meter of surface is calculated taking into account the thickness of the wall in the presence of seams of a certain size. The number of squares is the basis for assessing total needs. However, in addition to what is discussed above, the builder needs to know exactly the weight of cement per cubic meter of structure. The first aspect that affects the consumption of the building mixture is the type of brick. For a hollow product, more solution is required. The amount of cement in the binder mixture is determined by the strength criteria of the structure and the brand of cement. It is generally accepted that when laying one cubic meter of ordinary (classic) brick, certain volumes of mortar are used.

Table 2. The consumption rate of the solution

Type of masonry | Wall thickness (cm) | The volume of solution (cubic m) |

0.5 bricks | 12 | 0.189 |

1 | 25 | 0.221 |

1,5 | 38 | 0.234 |

2 | 51 | 0.240 |

2,5 | 64 | 0.245 |

Larger bricks due to less frequent crosslinking reduce mortar requirements. 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 grades are different, the higher - the more expensive, but the more expensive - the less it is needed to provide the necessary strength. The easiest way to calculate the amount of material in the construction of solid walls. A simple product of the parties determines the volume of the structure, then, taking into account the laying method, the amount of brick is determined, as well as the need for the 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 the mixture would be needed for the construction.** If a solution with a low grade of cement is used, mixed according to the 1: 1 scheme, then it will be required in the amount of 50% of the dry mixture, 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 be seen how much one standard bag holds, given that it is estimated in kilograms.

## Take stock into account

Masters advise to buy brick and cement not in exact calculation, but still add another 5-10% to the calculated results. This is the so-called rule of various construction circumstances. The stacker’s experience or product quality is not the last thing here. 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 per cubic meter. A standard bag holds 25 or 50 kilograms. The conversion of cubic meters into kilograms is possible using the density of the hardener. Typically, this figure 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. 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 be used. Higher strengths allow less use. Low strength determines a larger volume, a high grade reduces the volume in use, but increases the price of one bag of products. In practice, you need to know that a bucket of 10 liters can hold 12 kilograms of sand and 14 kg of cement. Playing with the quality of materials and the dimensions of the brick, cement grade 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 a tolerance of material consumption plus 5-10%. Who does not want to overpay, he must be able to confidently use the calculator and simple mathematical operations. Accurate estimates are the first thing to do. Competent purchase and delivery is the second condition. High-quality installation work completes the job.
