Jun 27, 2018 · Generally, M20 grade concrete is predominantly used for construction purposes. M20 = 1: 1.5: 3 (Cement:Sand:Aggregates) = (a:b:c) Quantity Of Cement: Quantity of cement = Dry volume x (a/{a+b+c} Quantity of cement = Dry volume x (1/{1+1.5+3}) for M20 grade concrete.

To find the design mix ratio, divide the calculated value of all materials by the weight of cement. Therefore Mix Design Ratio of M20 Grade concrete by weight is Cement: F.A: C.A: Water = 1 : 2.17 : 3.4 : 0.55. Note: This is a Design mix ratio by weight which is different from the Nominal volumetric mix ratio.
