COMPARATIVE STUDY ON COMPRESSIVE STRENGTH OF FLY ASH CONCRETE

Cement manufactured release large amount of carbon dioxide. So there is an instantaneous require to manage the use of cement. This research mainly deals with the replacement of cement by fly ash taken in variable proportions and analysing the effects of fly ash concrete. The concrete mix is prepared by varying the proportions of fly ash for 30%, 40% and 50% of cubes and prisms cured in normal water up to for 7 and 28 days. Compressive strength and flexural strength for hardened concrete are verified and the results are analysed.
