How to Calculate Number of Bricks and Quantity of Cement and Sand in Mortar

This exclusive video tutorial is presented by L & T - Learning Technology. The video tutorial will help you how to calculate number of bricks and quantity of cement and sand in mortar.

We have used modular brick having size 190 mm * 90 mm * 90 mm. We have chosen mortar thickness = 10 mm.

Ratio of cement and sand is 1:6 where 1 is cement and 6 is sand.

We have considered volume as 1 cubic meter

Volume of 1 brick with mortar = (190+10) * (90 +10) * (90+10) = 200 * 100 * 100 = 0.002 cubic meter

Number of bricks in 1 cubic meter = 1/0.002 = 500 numbers

Volume of 1 brick (without mortar) = 0.19 * 0.09 * 0.09 = 0.001539 cubic meter

Volume covered by 500 numbers of brick = 001539 * 500 = 0.769 cubic meter

Volume of mortar = 1 – 0.7695 = 0.2305 cubic meter in wet condition

Dry volume of mortar = 0.2305 * 1.33 = 0.306565 cubic meter

Cement = 0.306565 * 1/7 * 1440 = 63 kg = 1.26 bags

Sand = 0.306565 * 6/7 * 35.3147 = 9.28 cubic feet.
