Which cement is best for concrete slab construction? OPC or PPC?
Tanveer

See lessmainly OPC is used for RCC, PCC work, reason for that is high compressive strength in less period of time with proper curing
PPC can be used for plaster, masonry work or waterproofing as strength is not major criteria
PPC has an edge on OPC as PPC has slower rate of heat of hydration. Thereby PPC is prone to less cracks & reduced shrinkage), better workability and finishing (as fly ash based cement are spherical in shape and finer in size).
PPC is cheaper than OPC
