Dry volume of total materials is equivalent to 1.54 times the volume of wet concrete. Hence let us take the quantity of cement mortar as 1.54 m 3. Quantity of cement. The formula to calculate the volume of cement is as follows: (1.54×1)/(1+1.5+3)=0.28 m^3. Since the cement is available in bags, volume of 1 cement bag is 0.0347 m 3.
