The waste products of the factory mainly steel slag and GGBFS (ground granulated blast furnace slag) are used and recycled to gain concrete of different requirements related to strength and durability. In this research, it is intended to examine the impact of ground granulated blast furnace slag and steel slag replacement for cement and fine aggregate respectively. Both materials are taken from a factory of reinforcement bars which is located around Akaki kality sub-city, known as Akaki steel factory. The research additionally addresses X-ray diffraction (XRD), Scanning electron microscope techniques (SEM), and chemical composition of major oxides and minor oxides of the blast furnace slag. The main objective of this research targets in investigating an experimental aspect of replacing by-products of steel slag and ground granulated blast furnace slag partially on concrete production. It addresses the issue of a more expedite and urgent issue of our globalized world, climate change by replacing part of the concrete with these waste products. The followings are the main steps to carry out the researchAnalysis of properties of materials used as steel slag and ground granulated blast furnace slag. Blast furnace slag and steel slag mixed concrete mix design for partial substitution of cement and fine aggregate respectively. Find out the optimum replacement level of steel slag and that of ground granulated blast furnace slag in concrete. The thesis puts forward an experimental based analysis to determine the extent to which the industrial waste materials play a role in partial substitution of fine aggregate and cement in the preparation of concrete. From the experiments demonstrated flexural, tensile, and compressive strength of concrete is higher when GGBFS is replaced up to 5% of the cement and that of steel slag up to 30% of the sand.
