Suppose Concrete Grade is M15 i.e. 1:2:4,Then For
calculating the cement, sand & agg,You Have to add 50% as
Bulkage(i.e Wet Volume)
Then For 10 Cum qty.
Add 50% in This Qty
Total Qty =10+(10*50%)=15 Cum.
=15/(1+2+4)= 2.14(This Is a constant)
For Cement = 2.14 x 1 x 28.8=60.51 bags(Say 61 bags for 10 Cum)
(28.8 is wt of one bag in cum is 1440/50)
1440 is dencity of cement in Kg/Cum.& 50 is wt of one bag In Kg.
For Sand = 2.14 x 2 =4.28 Cum Sand.
For Agg = 2.14 x 4 =8.56 Cum Aggrete
