How to calculate no of bricks in 1 cubic meter

Before doing any type of brick work quantity should be known. Here are some basic steps for taking out brick work quantity in details. After knowing the 1-meter cube volume we can calculate the remaining quantity very easily by just multiplying 1 meter cube result of the desired volume.

Before start of calculation some basic data should be known:

1) The width of the wall which are going to built

2) Number of openings in wall like ( Doors , windows)

3) Size of brick or which type of bricks are going to use

Let’s take an Example o understand well

Example:-

Let’s assume we have to construct the wall having a length 1m, width 1m and height 1m. the size of brick is going to use is 190mm x 90mm and mortar thickness is 10mm with mortar ratio 1:4 so :

1) Calculate the number of bricks

2) Quantity of Cement

3) Quantity of sand

This calculation can take in to two steps:

1) Brick calculation

2) Mortar Calculation

As we have volume of brick is = ( 1 x 1 x 1 ) = 1 cube

Step – 1

Volume of 1 brick = 0.19m x 0.09m x 0.09m = 0.001539 meter cube

volume of 1 brick with mortar = 0.2m x 0.1m x 0.01m = 0.002 meter cube

Numbers of bricks in 1 cum = Total volume / volume of bricks with mortar

= ( 1/0.002) = 500 nos of bricks

Step -2 Mortar calculation

Volume covered by 500 bricks in 1 cum

= ( Bricks number x volume of 1 brick )

= 500 x 0.001539

= 0.769 cube meter

Mortar Volume

= ( 1 – 0.769 )

= 0.23 meter cube ( wet volume )

Dry Volume

= 0.23 x 1.33

= 0.3 meter cube ( Dry volume )

Note :- 1.33 is a constant

Cement 

= ( Dry volume x ratio x density of cement ) / ( sum of ratio )

= ( 0.3 x 1 x 1440 ) / 5

= 86.4 kgs / 50

= 1.72 bags

Sand

= ( Dry volume x ratio x 35.28 ) / ( sum of ratio )

= ( 0.3 x 5 x 35.28 ) / 5

= 10.58 cubic ft.

Result

Brick = 500 nos

Cement = 1.72 bags

Sand = 10.58 cubic ft.

Note:- These ratio may change by changing the dimension of the mortar thickness or size of the bricks as well as the mortar ratio 1:4 , 1:6 etc.
