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.

We'll go into the ins and outs of mix ratios in more detail below, but to simplify, a good concrete mix ratio for a concrete floor is: 1: cement 2: sand 4: coarse aggregates (for concrete slabs) When mixing, it's important that the concrete is placed within half an hour to ensure consistency and easy placement.
