Sustainability Issues: • Each ton of cement production-one ton of carbon-dioxide, 1 kg of sulphur dioxide (SO2), 2 kg oxides of nitrogen (NOx) and 10 kg dust into the atmosphere (Zhang et al., 2018) • Shortage of Landfill sites Optimum Solution: Geopolymer concrete (GPC)- novel form of concrete, synthesized by the alkali activation of source materials (aluminosilicate rich materials) ( Davidovits, 1991). On Site Feasibility Problems: • Highly corrosive alkaline solution-based reagents • Heat Curing Feasible Solution: Dry Mixing Technique • Powder-based reagents: required in less quantity • Source Materials: aluminosilicate rich materials • No need of heat curing
