Concrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. These mix ratios are decided based on type of construction and mix designs. However, building codes provides nominal and standard concrete mix ratios for various construction works based on experience and testing.

Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.

In a normal mix concrete, the proportions of concrete are prefixed. Typically, nominal mix is used for small-scale constructions. For instance, in the case of M15 grade concrete, the ratio of cement to sand to aggregate is 1:2:4 which is a fixed ratio. Concrete grades from M5 to M20 come under the category of nominal mix concrete.
