An Experimental Study on High Strength Geo Polymer Concrete

Abstract: Geopolymer concrete (GPC), rich in aluminosilicates and activated by alkaline solutions, offers superior durability, thermomechanical properties, and reduced environmental impact compared to conventional concrete. This eco-friendly material uses fly ash, GGBS, and silica fume, with optimized binder ratios like 35:50:15. Ambient curing enhances sustainability by eliminating the need for heat curing. Experimental studies reveal the benefits of incorporating brass-coated steel fibers, with 2.0% achieving optimal mechanical strength. AURAMIX 300 superplasticizer improves workability, while slag content enhances strength and bonding. Though costlier, HS-GPC's lower carbon footprint and high performance make it a sustainable alternative to traditional concrete.
