COMPARATIVE STUDY ON COMPRESSIVE STRENGTH OF FLY ASH CONCRETE

We are vigilant that an intense damage is done to environment in the manufacturing process of cement which involves emission of majority of carbon associated with other chemicals. There are evidences from researches that every one ton of cement manufacture need to control the usage of cement. On the other hand material wastes such as fly ash is difficult to dispose which in turn is an obstacle to the environmental safety. Fly ash is a finely divided residue resulting from the combustion of pulverized coal and transported by the flue of boilers that carries gaseous combustion away from the point of combustion. The fly ash initially imparts high strength to concrete and also reduce the permeability of concrete. It was obtained from Thermal power station, dried and used. This project mainly deals with the substitution of cement by Fly ash taken in fixed proportions and analyzing the effects of fly ash blended concrete.
