Estimation of concrete

Calculation of concrete for slab, beam and column per cubic meter
For M15 grade
Mix proportion (1:2:4)
Dry Volume = 1.45 m3
1. Cement Qty = (1.45/(1+2+4))*1
                       = 0.273 m3
                       = 0.273 * 1440 (Density)
                       = 393.12 kg
To calculate no. of bags = 393.12/50
                                      = 7.86 bags
2. Qty of sand = (1.45/(1+2+4))*2
                       = 0.414 m3
                       = 0.414 * 1350 (Density)
                       = 558.9 kg
3. Agg Qty = (1.45/(1+2+4))*4
                  = 0.828 m3
                  = 0.828 * 1850 (Density)
                  = 1531.8 kg
Total Qty  :
1:2:4  = 393.12 : 558.9 : 1531.8
 
          = (Cement : Sand : Agg)
