of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregates. For, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are
It has a high effect on the strength and workability of concrete. So, in this article, we''ll briefly discuss the calculation, maximum and minimum value of the watercement ratio for M10, M15, M20, and M25, etc. In the concrete Mix design, the ratio between water to the amount of cement (by weight) is known as a watercement ratio.
