for 1cum how much bag of cement is used for M20 grade

Answer Posted / pramod vs gowda

The mix proportion is 1:1.5:3
We find out the quantity of cement for 1cum
Dry co-efficient of cement is 1.52
Unit weight of cement 1440
Then
(1/(1+1.5+3))*1.52=0.276
0.276*1440=397.44kg/m3
1 bag cement is equal to 50 kgs
397.44/50=7.9488
So Approximately 8 bags of cement is for 1cum
