MASONRY WALL MATERIALS CALCULATION

Suppose you have to construct a wall of length=4m, breadth=1m, & height=2m.

Volume=4*1*2=8m³

For 1 m³of stone work, you require 1.25 m³of stones. (Extra 0.25 m³ are to compensate for wastage during actual construction)

Therefore, quantity of stones required=8*1.25=10m³

Dry material required for 1m³of stone work=0.42m³

Therefore, total quantity of dry material (cement and sand) required=10*0.42 = 4.2m³

Cement and sand are taken in the ratio of 1:4 in case of stone work

Let the quantity of cement be represented by xm³

Therefore, x+4x = 4.2 m³

X=0.84 m³

Therefore quantity of cement required = 0.84 m³

1 m³of cement = 30 bags of cement

Therefore, 0.84 m³ of cement = 25.2 = 26 bags approx.

And quantity of sand required = 4*0.84 = 3.36 m³
