Abstract: Concrete is the highly used building material around the world. Tons of CO2 is evolved during manufacturing process of cement. This CO2 emission has massive effect on nature and to reduce it blended concrete has been used. Now days, use of cementitious materials are increasing rapidly. Blended concrete is the concrete in which cement is mixed with different proportions of mineral admixtures such as GGBS, silica fume, fly ash etc. In present study, partially replacing of cement with Fly ash and GGBS with three different proportions. Fly ash and GGBS are by-products from coal and iron industries. Here, M40 grade control concrete which is 0% replacement of cement and Blended concrete with 3 different combinations. Both the results will be compared. Cement is substituted by GGBS in 15%, 20% 25% proportion and substituted by Fly ash in 15%, 20% & 25% proportion. These specimens are tested for Split tensile strength, compressive strength and bending strength at the age of 7 and 28 days. Using these industrial wastes not only increases strength but also makes the concrete eco-friendly.
Keywords: Split Tensile Strength, Compressive Strength and Bending Strength, GGBS and Fly Ash.
