Description

High population growth has increased the requirement for infrastructure development tremendously. Building materials like ordinary portland cement which is the primary component in concrete is growing due to the increased demand for new infrastructure. Concrete is the world's second most consumed material. Special concrete called Geopolymer concrete (GPC), is grabbing the interest of researchers as substitute to ordinary portland cement concrete (OPCC). Manufacture of cement is highly energy intensive and leads to large quantity of CO2 emission to atmosphere which in turn leads to global warming. Thus, replacement of cement with geopolymer material minimises pollution in two ways: by lowering cement consumption and utilisation and by lowering CO2 emission. Various industrial and agricultural waste materials like fly ash, metakolin, ground granulated blast furnace slag, silica fume, rice husk ash, sugarcane bagasse ash etc. are abundantly available. These aluminosilicate sources have been widely employed to develop geopolymer concrete with high strength, thermal resistance, and durability. This article is a review of research on the durability aspects of geopolymer concrete, its most significant durability parameters like resistance to acid attack, sulphate attack, water absorption, porosity, sorptivity, rapid chloride penetration, wet and dry cycle have been reviewed to comprehend these vital issues. 2023
