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
