Grade of concrete mix ratio refers to the proportion of cement, sand, and aggregate in a concrete mix.

• Grade of concrete mix ratio is typically represented as M10, M15, M20, etc.

• For example, M20 concrete mix ratio means 1:1.5:3 - 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• The mix ratio is crucial for achieving the desired strength and durability of the concrete.

• Different grades of concrete require different mi...read more
