As more concrete is needed to satisfy infrastructure demands, conventional cement production produces large amounts of CO2, which has a negative impact on the environment. An environmentally acceptable substitute for cement is geopolymer concrete, which uses alumino-silicate ingredients and an alkaline activator. Fly ash and ground granulated blast furnace slag are examples of aluminosilicate materials that are chemically activated to form geopolymer binders. The scarcity and expense of natural sand can also be addressed by partially replacing fine aggregate with tire rubber waste crumbs. This scientific investigation looks at how the molarity of NaOH affects rubberized geopolymer concrete’s (RGPC) compressive, flexural, and split tensile strengths. Additionally, this study looks into how curing techniques like ambient and oven curing affect the mechanical characteristics of RGPC.
