WhatsAppFirst of all, we need to know what substances are contained in concrete. The four materials of water, cement, sand, and gravel are the most basic components of concrete. Secondly, we need to choose according to the purpose of the concrete. conventional gradec20c25c30concrete mix ratio, the following design methods are carried out.
WhatsAppConcrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand 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.
