How many bricks in 1m3 of masonry: how to calculate the amount of material
Despite the new technologies that fillthe construction industry, ceramic brick is still an actual material for the erection of walls, partitions, fences and arches. This is not surprising: it is durable, holds heat well, insulates sound in rooms, and does not require additional finishing of external walls, if you beautifully arrange the seaming. We'll figure out how many bricks in 1m3 of masonry, how to find out the right amount of material.
"Dry" calculation
Before the construction of a house, a project is always created,in which all the materials for the erection of structures are laid. According to the drawings, the material is calculated, which will show how many bricks or other components need to be purchased, and also help determine the future labor costs, respectively, the approximate cost of the entire event. To minimize losses, both financial and material, you need to know as precisely as possible the number of elements that will participate in the construction.
Types of bricks
- Single (1,0) - standard ceramic red or yellow color with dimensions of 250x120x65 mm. Knowing its parameters, we learn how many pieces of brick in 1m3: without taking into account the seams and gaps - 512.
- The one-and-a-half (1.5) differs in height: 250x120x88 mm. Basically, they are white "silicate" bricks, they lay the walls of buildings, when the speed of erection is important, the appearance of such structures does not differ solemnity. 1m3 contains 378 pieces of such elements.
- Double (2.0): 250x120x138 mm. The increased size of this brick allows you to quickly build objects, but such elements are not easy to install neatly and with a beautiful bar. Because it is often used for laying the inner layer of the wall. There are 255 double bricks in the cubic meter.
In the data given, only the geometrical dimensions of the masonry and its elements are taken into account, but seams and gaps are not taken into account.
We calculate the project masonry per cubic meter
When building walls, the bricks are connected to each other by means of a cement slurry. It is laid with a layer of a certain thickness, sufficient to ensure the adhesion and strength of the future design:
- for horizontal - 12 mm (in some places it is allowed 10-15 mm);
- for vertical joints - 10 mm (can be 8-15 in separate places).
When making gaps of this value, the brickthe wall will last long, the masonry will be strong and reliable. With a smaller size of joints or with an excess of mortar in them, the strength conditions will not be met, which means that the risk of deformation or destruction of walls is high.
The erection of masonry requires the hand of a professional: masons easily and quickly erect walls, experience allows them to create seams of the right size without much difficulty. If you decide to create brick structures on your own, it will take a lot longer.
Now calculate how many bricks in 1m3 of masonry, taking into account the gaps on the seams:
- single - 394 pieces;
- one-and-a-half bricks require 302 elements;
- double - 200 pieces.
Now you can determine the number of bricks needed for the entire building, but only directly involved in the masonry.
Dependence of the amount of material on the thickness of the structure
As you know, masonry are of different types,the bandage in them is different. In addition, you need to consider the thickness of the wall. At small volumes, this factor can be neglected, with a large width, the calculation error may come out sideways and the material will not suffice.
Another way to determine the volume of bricks in 1m3 masonry is to use the size of a square meter of the side wall surface.
To simplify the problem, we give a table in which the dependence of the number of bricks on the thickness of the masonry is shown.
Number of bricks, pcs. | Thickness in bricks (building designation) | Wall thickness, mm | ||
Single (1.0) | The one-half (1.5) | Double (2.0) | ||
51 | 39 | 26 | 0,5 | 120 |
102 | 78 | 52 | 1,0 | 250 |
153 | 117 | 78 | 1,5 | 380 |
204 | 156 | 104 | 2,0 | 510 |
255 | 195 | 130 | 2,5 | 640 |
For example, we will determine how many bricks in 1m3 of masonry walls are 5 meters long, 2.7 meters high and 510 mm wide:
1) Find the side wall area: 5 x 2.7 = 13.5 m2.
2) We look for value in the table - for a wall from a single brick the consumption per 1 m2 is 204 pieces.
3) We are looking for a total of: 13.5 * 204 = 2754 pieces.
Similarly, it is desirable to calculate all the stone structures, so you can accurately know the required amount of material.
Do not forget about the stock
Ceramics - the material is very fragile, when transferred toThe mason's workplace has a risk of breaking a couple of bricks. Also, losses occur when the stone is divided into fragments for spreading end pieces or complex shapes. Therefore, when calculating the right amount, consider the possible losses and take the material with a margin - at least 5-7% of the total. When constructing complex structures or using the method of stump clutch, the amount of marriage increases to 15-20%.
So, to determine how many bricks in 1m3 of masonry, you need:
- determine the volume and area of the walls;
- choose the method of masonry;
- take into account possible losses.
When you know the final result, you can easily calculate the cost of erecting a stone structure by selecting reliable suppliers.
