PCC stands for Plain Cement Concrete, which is a construction material made by mixing cement, sand, aggregate, and water.

• PCC is used as a base for flooring, roads, and other structural elements.

• It provides a smooth and level surface for further construction work.

• The mix ratio of PCC is typically 1:3:6 (cement:sand:aggregate).

• PCC is not as strong as RCC (Reinforced Cement Concrete) but is suitable for non-structural app...read more
