What is Plain Cement Concrete (PCC) in Construction

2019-2-7  The mixture of cement, fine aggregate (sand) and coarse aggregate are generally called plain cement concrete (PCC). Before starting any R.C.Cor masonry work directly on the excavated soil, PCC is done to form a levelled surface and to avoid laying concrete on soil directly so as to avoid mixing/ with soil and also to prevent soil extracting water from PCC thereby weakening it.

The Differences Between Cement, Concrete, and Mortar

2021-6-30  The Spruce / Liz Moskowitz. Concrete . Concrete is a complete building material used for foundation walls, concrete slabs, patios, and many other masonry structures. It is uniquely versatile because it starts out as a simple, dry mixture, then becomes a flexible, semi-liquid material capable of forming into any mold or shape, and which dries into the hard-as-rock material we know as concrete.
