Concrete mix design is a method of calculating right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures. The Concrete mix design Concrete Mix = Cement:Sand:Aggregates. For a mix design of concrete, we have to follow various steps, calculations, and laboratory testing to find the right mix proportions.
