Specifications for Plain Cement Concrete (PCC) | Building Estimation and Costing

Plain Cement Concrete (PCC) is a construction material generally used as a binding materials and is composed of cement, (commonly Portland Cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone or granite, plus a fine aggregate such as sand), water, and chemical admixtures.

In my earlier articles, I discussed types of specifications, purpose of specifications, RCC specifications, Specifications for Brick masonry in Cement Mortar, Coursed Rubble Masonry Specifications. In this article, we are going to discuss in detail various specifications that are to be given before the initiation of PCC work.
