EFFECT OF SALINITY OF WATER ON STRENGTH OF CEMENT CONCRETE AND GEOPOLYMER CONCRETE

Concrete users around the world are second only to water consisting main ingredient as cement. Ordinary Portland Cement is conventionally used as the primary binder to produce concrete production of cement, produce one ton of emission of CO2 every ton of cement produced. To produce cement, electricity is also required to run the cement production plant. Generation of electrical power produces fly ash as a waste material in thermal power plants Thin cycle is causing environmental pollution, waste disposal problem also. The project aims at replacing the cement. Besides the government has restricted to use the river sand in concrete.
