The global consumption of natural aggregates and cement is rising at an alarming rate due to the vast growing in construction industry. At the same time, the steel industries are generating large amounts of by-products in the form of electric arc furnace (EAF) slag, ladle furnace (LF) slag and ground granulated blast furnace slag (GGBS). These slag by-products can potentially be reused and utilized as partial substitute of the common constituent materials in concrete such as the aggregates and cement. This chapter thus investigates the influence of using the local EAF and LF slags as 40% aggregate replacement along with the GGBS at 25% cement replacement in concrete. The results demonstrated that improvement in the properties of concrete (such as compressive strength, water absorption, surface resistivity and mass changes) can be achieved with EAF slag as partial coarse aggregate replacement, and these properties can be further enhanced with the use of GGBS. This points towards potential of the co-utilization of the EAF slag and GGBS in a sustainable concrete mixture to maximize the use of these industrial by-products.
