Mathematical calculations of bricklaying

How to calculate the number of bricks needed in bricklaying mathematical calculations

In the mathematical calculations of bricklaying, the amount of materials used for brick walls with pressed bricks and machine bricks with a thickness of up to 2 bricks is the unit selected for price analysis for brick walls with a thickness of up to 2 square meters, which is considered according to the following points.

Ease of calculating the amount of work done (meters) Resolving discrepancies caused by the non-matching of the thickness of the implemented walls with the theoretical sizes included in the executive plans Matching the wages with the difficulty of performing the work of different types of walls

Calculate the amount of bricks per cubic meter of the wall

The number of bricks for the wall is 2.5 bricks per row = 77.22 molds
The number of bricks for the wall, 3 bricks in each row = 4.57 + 22.77 = 27.34 molds
Number of bricks for the wall: 3.5 bricks per row = 1.9 + 77.22 = 31.87 molds
Number of bricks for the wall: 3.5 bricks per row = 1.9 + 77.22 = 31.87 molds
The number of rows per square meter of the wall = 88/313 rows

Number of bricks per square meter of wall for

Wall 2.5 bricks = 77.22 x 13.88 = 316 molds
Wall of 3 bricks = 27/34×13/88=39/48 mold
Wall 3.5 bricks = 31/87 x 13/88 = 442/35 molds
Wall of 4 bricks = 36/44 x 13/88 = 505/78 molds
The number of bricks per cubic meter = the number of bricks per square meter times the thickness of the wall
Therefore, in the mathematical calculations of bricklaying, the number of bricks per cubic meter for a wall of 2.5 bricks with a thickness of 54 cm is 585 molds.
A wall of 3 bricks with a thickness of 65 cm, 584 molds
3.5 brick wall with 76 cm dimensions = 582 molds
A wall of 4 bricks with a thickness of 87 cm = 581 molds
And on average, the number of bricks in each cubic meter of a brick wall with pressure bricks arranged in the form of seats will be equal to 583 molds.
which is equal to 583×1.07=624, including 7% drop.
Calculation of the volume of mortar used per cubic meter of the wall
The volume of a pressed brick mold = 1100 cubic centimeters
The total volume of bricks in one cubic meter = 1100 x 583 = 673365 cubic centimeters
Volume of one cubic meter of wall = 1000000 cubic centimeters
The volume of mortar without loss is equal to 100000-67365=326635.
The volume of mortar with a 2% decrease is equal to 326635 × 1.02 = 333167 cubic centimeters or 333 liters.
Calculating the necessary materials for laying on the work with three-centimeter brick

Calculation of the number of bricks in the mathematical calculations of bricklaying

The number of bricks in a row = 52/4 molds
The thickness of the mortar band = 1 cm
The thickness of one row with 3+1 mortar = 4 cm
The number of rows in one square meter = 25 rows
The number of bricks in one square meter = 25 x 51.4 = 112.7, brick loss = 5%
The number of bricks in one square meter including the loss = 7.112 x 1.05 = 118 molds
Calculating the amount of mortar used if a three-centimeter brick is used.
Persistence mortar volume = 10,000 cubic centimeters
Mortar surface in one row = 100 x 10.5 = 1050 square centimeters
The number of rows in one square meter = 25
The volume of mortar in one square meter = 25 x 1050 = 26250 cubic centimeters
The total volume of mortar = 26250 + 100000 = 36250 cubic centimeters
Mortar loss = 2%
Calculating the amount of difference in materials used if a 3 cm brick is used instead of a 5.5 cm brick.
Most of the wooden houses that are lined with three-centimeter bricks are reinforced with grade 2 or 3 pressed or machine-made bricks and are arranged in the form of chairs. Due to the different thickness of the bricks, the joints in the walls of one brick are not regular.

Calculate the volume of mortar

The volume of mortar for general joints = number of joints x height of joint x length of joint (cubic centimeters)
Mortar volume for joints between two ends of bricks = number of joints in one row x number of rows x width of joint x thickness of joint x height of joint
