Answer / kanchan
M20=1:1.5:3,
1cum concrete with water= 1.57cum dry material
For Cement- 1/(1+1.5+3)*1.57=0.285cum=8.55bags
For Sand- 1.5/(1+1.5+3)*1.57=0.43cum
For Aggregate -3/(1+1.5+3)*1.57=0.86cum
M25 -1:1:2
For Cement- 1/(1+1+2)*1.57=0.39cum=11.77bags
For Sand- 1/(1+1+2)*1.57=0.39cum
For Aggregate -2/(1+1+2)*1.57=0.78cum
