The difference between OPC & PPC is based on Flyash content in the cement. PPC will have more flyash content which adds fineness to cement. The setting time of the concrete will vary. PPC setting time shall be more than the OPC cement but the ultimate strength criteria will be same on sufficeient curing time. PPC shall be used for non structural members such as plastering etc., which is much free from crack development as it takes gradual setting.
