What is a concrete mix?

A concrete mix is made up of five basic components in varying proportions: cement, water, coarse aggregates, fine aggregates (i.e. sand), and air.

Supplementary components, such as pozzolanic minerals and chemical admixtures, can be added to the mix to give it desired qualities.

Cement, sand, gravel, and water are used to make concrete.

To attain optimal power, these substances should be blended in the following proportions: 1:2:3:0.5. That is one part cement, two parts sand, three parts gravel, and one-half part water.
