Abstract: Cement is the most important material of the construction industry, but its manufacturing inflicts bad to the environment by emitting carbon dioxide into the atmosphere. Reduction of these emissions, while meeting the ever increasing demand for the infrastructure across the globe is a challenge for the sustainability of the industry that attracted the focus of academicians, domain experts and researchers to objectivise their work to explore the alternatives to the cement. Many alternatives have come into discussions, as result of such work by the researchers, to examine further to substantiate their use in the industry. Some of such alternatives for the partial replacement of cement are Fly-ash, GGBS, Rice Husk, Silica Fumes, Meta Kaolin etc., and many of them are industrial by-products. This project deals with replacement of cement content in concrete with the combination of fly-ash and GGBS as blending material with the limiting percentages individually. As recommended by the respective IS standards, 25-55% of Fly ash is replaced with cement. The optimum value is noted and considered as constant throughout. In this paper, Fly ash (obtained) content is kept constant and different percentages (up to a maximum of 60%) of GGBS content is tried to conclude and report the findings on variations of concrete properties like flexural strength, compressive strength, Load vs. Displacement for different combination of varied GGBS content for a constant Fly ash content. The load carrying capacity is noted comparatively for Conventional and Composite concrete.
Keywords: Fly Ash, GGBS, Flexural Strength, Load Carrying Capacity.
