How To Make Concrete - Some Vital Information

The concrete is formed by mixing paste and aggregates, or rocks. The paste, made of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. With the help of a chemical reaction known as hydration, the paste solidifies and attains strength to develop the rock-like mass called concrete.

Concrete is plastic and compliant when mixed lately. It becomes strong and long-lasting when solidified.
