Compressive Strength of Concrete with Partial Replacement of Cement by Fly Ash

During last few decades several researches have been carried out on blending of the fly ash in Ordinary pozzolanic cement OPC . In the present study fly ash is used in Portland pozzolanic material PPC concrete as partial replacement of PPC. Fly ash is a pozzolanic material which produces calcium silicate hydrate C S H when reacts with free lime present in cement during the hydration. This paper present the experimental result carried out to determine workability and compressive strength of concrete at different replacement of PPC. M 25 grade of concrete 1 1.53 3 at w c of 0.42 was designed as per IS 10262 2009. Result shows that PPC can be replaced up to 20 by fly ash without compromising compressive strength of concrete.
