Which is better for use in slabs : PPC/PSC or OPC ?
I would like to know which type of cement is better for use in slabs: PPC/PSC or OPC?
Generally, PPC/PSC cements are recommended for use in slabs as they have a lower heat of hydration, which reduces the risk of thermal cracking. They also provide better workability, which makes it easier to place and compact the concrete. OPC, on the other hand, is more commonly used in situations where high early strength is required. Is there anything specific you would like me to explain?
