Abstract: Today, with the increasing rate of construction, concrete is being manufactured in the world on a large scale. It is important for the growth of infrastructure for many decades. But concrete consumes a lot of natural resources due to which it is not considered as an environment-friendly material. Portland cement is a major constituent of concrete which generates carbon dioxide gas during its production which in turn adversely affects the environment. Also, the other ingredients such as sand and coarse aggregates are depleting at a faster rate thereby increasing the cost of construction. Due to this, there is a need to identify alternate materials for cement, sand and coarse aggregates. In this study, GGBS, fly ash and recycled aggregates addresses this issue. The main objective of this research is to analyse and identify the effects of recycled waste materials in different proportions on Compressive and Split tensile strength of concrete. Ground Granulated Blast Furnace Slag (GGBS) (as a partial replacement of cement), Fly Ash (as a partial replacement of sand) and Recycled Aggregates (as a partial replacement of coarse aggregates) were the different recycled materials used. Taguchi’s Approach is being used in this study to obtain different combinations of percentage replacement. It was observed that when cement, sand, and coarse aggregates are being replaced by 30% GGBS, 30% Fly ash and 20% Recycled Aggregates respectively, the compressive strength and split tensile strength test values show better results than conventional mix concrete.
