ABSTRACT

Alkali-Activated materials are a good alternative to Ordinary Portland Cement (OPC). They not only save energy and reduce CO₂, emissions but also amplify the durability performance of mortar and concrete. Alkali-Activated materials can also assist in compelling the problems related to illegal landfilling of plots. Industrial by-products like fly ash, ggbfs can be alkali-activated by using alkali-activators and can resolve the current issues of the environment. In this paper, alkali-activated concrete is prepared by using Waste Brick Powder (WBP) which is replaced by Ground Granulated Blast Furnace Slag (GGBFS) in different proportions as a binder. Sodium Hydroxide (NaOH) and Sodium Silicate (Na₂SiO₃) solutions are used as alkaline activators. The alkali-activated concrete specimens are prepared by using two molarities 10M and 12M and cured for 7 and 28 days under ambient temperature. After curing, mechanical properties like compressive strength, flexural strength, and split tensile strength are studied and the results were discussed.
