PLAIN CEMENT

Plain cement concrete (PCC) is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportions. It does not contain a steel rod. If steel is kept in the concrete, then it is called RCC.

These ingredients are mixed together in a definite proportion to form a plastic mass, which is poured into desired shape moulds called as forms.

This plastic mass hardens on setting and we get PCC. The hardening of this mixture is caused by a chemical reaction between cement and water.
