Evaluation of Strength of Plain Cement Concrete with Partial Replacement of Cement by Meta Kaolin Fly Ash

Abstract

The present report deals with the effects of mineral admixtures, by partial replacement of cement, in terms of improved performance on compressive and flexural strengths. Experimental work was carried out to investigate the effect of Meta kaolin and Fly ash by partial replacing cement and keeping same water cement ratio to ordinary concrete & meta kaolin and fly ash. In this program we are going to construct 48 cube samples of size 150mmx150mmx150mm for different percentages of Meta kaolin and Fly ash with partial replacement of cement will casted and tested. The concrete mixes had 0%,5%,10%,15% of Fly ash and Meta Kaolin, replacing cement partially, so as to determine the best proportion, which would give maximum compressive strength. It reveals that with 10%Meta kaolin and Fly ash each partial replacement of cement were found to be most favourable combinations for casting of concrete flexural members. Using the optimum mix proportion giving the best results in compressive strength of cube testing, beam specimens will casted and tested for their flexural strength. The dimensions of each beam will 750mm x150mm x 150mm.The beams Will tested on universal testing machine to verify their flexural strength after 7days, 28 days of curing with single point load. The results will compare with the beams of varying flexural strength of
