Abstract

Abstract: In the present global context, the use of environmentally sustainable friendly components in the manufacturing of concrete is a positive development. Due to the fact that many industrial by-products were used as a base material in the manufacturing of Geopolymer concrete, it was recognized as the most prominent one in line with the trend. Furthermore, geopolymer concrete was shown to be a feasible alternative to conventional Portland cement (OPC)-based concrete, resulting in a decrease in carbon dioxide emissions into the atmosphere. As a consequence, the impact of global warming has been mitigated, and environmental issues raised by OPC usage have been addressed. This research attempted to make geopolymer concrete under ambient curing circumstances using fly ash, Ground Granulated Blast Furnace Slag (GGBS), a decreased amount of alkaline activator, and bio-additives. In ambient-cured geopolymer concrete incorporating fly ash GGBS, a broad variety of attributes, including mechanical and durability parameters, were investigated. Mechanical tests were carried out, including the slump test, workability test, compression test, splitting tensile test, and flexural test. The durability attributes were assessed using the acid attack test, sulphate attack test, and chloride attack test.
