Portland Slag cement is produced by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement . Composition of PSC cement · -> It is produced with a combination of 45-50% clinker, 45-50% blast furnace granulated Slag and 3-5% of gypsum. · -> Application of PSC cement · -> It is used i n pre-cast concrete like pipe and block. Also used in structures like retaining wall, rivers, ports, tunnel etc. · -> It is used in ready mix plants also. Advantages of PSC Cement · ->It is gives low initial strength but gained equal or sometimes higher strength in higher ultimate strength. · -> It has low risk in alkali-silica reaction with aggregates and good resistance from sulphate and chloride attacks. · --> Due to its fineness it increase durability and reduced per
