Abstract

The optimum percentage of GGBS for maximum Flexure strength of 3.98MPa at 25% GGBS. Addition of GGBS to PQC mixes up to the optimum value has shown an increasing trend in Flexure strength. With further increase of GGBS content, Flexure strength has shown decreasing trend. The optimum percentage of Stone Dust for maximum flexural strength is decreased as increase the quantity of stone dust. Maximum value of flexural strength of 3.27MPa was obtained at 60% Stone Dust replacement. The flexural strength of GGBS (25%) and Stone Dust (40%) GGBS+MS-PQC is increased by 4.93N/mm2 to 5.12N/mm2 at 28 days as compared to Conventional PQC.
