OPC: OPC is categorised as 33 Grade, 43 Grade and 53 Grade. It is preferably used in Defence Services, Railway Sleeper making and in lean concrete structures. PPC: PPC is having better resistance to Sulphate attack and hence it is preferably used in Sea Shore, Dam constructions and in the earth work concreting to neutralise corrosion effect of soil and water under the earth’s crest. Due to higher fineness, mostly it is used in plastering work for smooth finishing.
