J.K. Cement - PSC
Portland Slag Cement (PSC) is an intimately interground mixture of Portland Cement Clinker & granulated slag (Non-metallic) which is a by product of Iron Blast furnace from steel plant. It is termed as Portland Slag Cement & is confirmed to IS 455:1989.
It has a special character of later compressive strength which is gradually increased after 3days, 7days & finally 28 days obtaining 50Mpa. This cement has less water requirement for concrete construction & also better workability can be achieved.
It is mainly used in special structure like pre-stressed concrete. It has highly corrosive resistance power, hence it can be widely used in coastal areas.
