Concrete Mix Ratio, Types, Proportioning of Concrete Mix

Determining the proportion of cement, fine aggregate, and coarse aggregate for concrete mix is known as the proportioning of concrete. The principle of proportioning aggregate is that the smaller particle will fill up the voids between large particles. A well proportioned concrete mix requires a minimum amount of cement per unit volume.
