NOTE – In case the coarse aggregate is not angular one, then also volume of coarse aggregate may be required to be increased suitably based on experience & Site conditions. For pumpable concrete these values should be reduced up to 10%. Therefore, volume of coarse aggregate =0.63 x 0.9 =0.57. Volume of fine aggregate content = 1 – 0.57= 0.43.

Concrete Mix Design Calculation : M20, M25, M30, M40 Grade Concrete Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.

Volume of concrete = 1 m³. Grade of concrete M20 (1:1.5:3) Find-out the Quantity of concrete (Wet volume and Dry volume) Wet volume of concrete = 1 m³. Dry volume = Wet volume x 1.54 (You can also take it as 1.50 to 1.55, But it became standard practice to considering 1.54 as multiplication factor). Dry volume of concrete = 1 x 1.54 =1.54 m³

III. TARGET STRENGTH . Apart from mix design, the strength of the concrete depends on other factors like mixing method, climate etc. Hence Target strength (F ck) should be more than designed characteristic strength (f ck).Target strength for m20 grade concrete can be …

Concrete Mix Ratio by Volume. Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. The volumetric mix ratio of M20 concrete is 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.
