Optimizing Concrete Strength and Sustainability by Using Blast Furnace Slag and Waste Glass Powder as Additives

ABSTRACT Construction industry intends to promote effective utilization of waste materials obtained from various sources to develop an eco‐friendly building material for high performance, life cycle sustainability, and reduction of carbon footprints globally. The current study focusses to produce concrete mix by using industrial wastes such as ground granulated blast furnace slag (BOF) and glass powder (GP). Samples are prepared by utilizing industrial wastes partially for M35 grade concrete. The ground granulated BOF and GP are used with 10%–40% and 0.1%–0.4%, respectively, as the partial replacement of cement. Under different curing periods, the specimens were characterized for their physical and mechanical properties. Test results were analyzed to check the workability, compressive strength, flexural strength, and water absorption of the sample mixes prepared. The highest compressive and flexural strength of the samples are found to be 46.23 MPa and 5.13 MPa, at the optimal replacement of BOF and GP in the proportion of 30% and 0.2%, respectively.
