How to calculate cement and sand quantities in cement mortar
As 1:1,1:2,1:4,1:6 ?

Answer Posted / prakash

Calculation Method
Plastering with CM 1:5 12 mm thick - 10 m2

Area to be Plastered = 10 m2

Thickness of mortar Layer = 12 mm = 0.012 m

Volume of mortar required = 10 x 0.012 = 0.12 m3

Add 15 percent allowance for undualation of surface & wastage = 0.018 m3

so, total volume of Mortar Required = 0.138 m3 say 0.14 m3

sand required for 0.14 m3 of CM 1:5 = 0.14 m3

cement required for 0.14 m3 of CM 1:5 = 0.14/5 = 0.028 m3

wt of cement required = 0.028 x 1440 = 41 kg

Is This Answer Correct ?    24 Yes 24 No
