Which is better, OPC or PPC?

pay per click Compared to OPC, it has low water permeability and produces highly durable concrete. Compared to OPC, PPC has a lower initial setting strength, but will harden over a period of time with proper curing. PPC is also cheaper compared to OPC. … OPC is ideal where fast construction is required.
