Concrete Mix Design Procedure and Example IS456

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 124 means that cement, fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
