Plain cement concrete (PCC) is an essential component of building construction and serves to prevent direct contact between reinforcement concrete and soil or water. This article covers the intricacies of PCC placement, providing information on the materials used, the procedure, dos and don’ts, and the benefits it brings to construction projects.
Material Used in Plain Cement Concrete
The general properties of the materials used in PCC are as follows:
1. Coarse Aggregate
The coarse aggregate used in PCC must consist of hard, broken stone, such as granite, that is free of dust, dirt and foreign matter. Ideally it should be 20mm or smaller and pass through a 5mm square mesh. Proper classification ensures that gaps do not exceed 42%.
2. Fine Aggregate
Portland Pozzolana cement (P.P.C) is the preferred choice for PCC and meets the required specifications regarding tensile and compressive stresses as well as fineness.
3. Cement
Portland Pozzolana cement (P.P.C) is normally used for plain cement concrete. It must comply with the specifications and have the required tensile and compressive stresses and fineness.
4. water
The water used in PCC must be clean and free of harmful substances such as oils, acids, alkalis, salts or organic formations. Drinking water with a pH of not less than 6 is recommended, adhering to the permissible limits for solids as per Clause
