Portland Slag Cement (birat Psc)
Portland Slag Cement is manufactured by intimately inter grinding a mixture of Portland Cement Clinker and Granulated blast furnace Slag (25-45%) with addition of Gypsum.
Birat PSC Slag Cement has distinct advantage. It has low heat of hydrationry low drying shrinkage and very low expansion which reduces the formation of micro cracks and improves the durability of construction.
Portland Slag Cement has the incredible feature of reduction in heat during hydration, increased lateral strength, improvement in work ability leading into less bleeding, better interface with aggregates resulting into inhibition of aggregate reaction.
This kind of cement is manufactured by grinding the Clinker with Blast furnace granulated slag and Gypsum. These elements are ground to desired fineness.
