Plain cement concrete (PCC) is used to provide rigid impervious bed to RCC in foundation where the earth is soft and yielding. PCC can be used over brick flat soling or without brick flat soling. Plain cement concrete can also called only "cement concrete (CC)" or "binding concrete". The thickness of PCC is normally 50mm over Brick Flat Soling (BFS). If we don’t use BFS below PCC then the thickness should be 75mm. when the PCC is used in car park area then the thickness should be 75mm over BFS.
