how to calculatecement, sand and coarse aggregate

This is a Volumetric Calculation. Assuming we need 2 m3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume. = (1/5.5)* Concrete Volume = (1/5.5)*2 = 0.3636 m3
