To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-
Concrete grade mixtures can be broadly categorised into design mix for higher-grade concrete and nominal mix for lower-grade concrete. Notably, the M25 ratio is primarily used for the latter. ... A. Class 25 or M25 concrete mix ratio is 1:1:2, which means a part of cement and a part of sand is mixed with two parts of coarse aggregate. Q. Is M20 ...
Concrete mix design is necessary to attain target strength in structures. Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates). So, for 4cu.m of M25 concrete, it is essential to contain 1cu.m of cement. Therefore, theoretically, for 1cu.m of M25 concrete, 0.25cu.m of cement is required.
