Clean technology for sustainable development by geopolymer materials

Abstract

Abstract Geopolymer materials have captivated as a promising material for building restoration due to their environmentally sustainable nature as well as their potential to use a variety of waste products as precursors. Numerous industrial, municipal and agricultural wastes can be used to create environmentally acceptable, sustainable, structurally sound geopolymer matrices. These new generation materials, fabricated by following the geopolymerisation reactions of alumino-silicate oxides with alkali activators, have the advantages of high mechanical strength, corrosion resistance, durability, fire resistance etc., and can serve as a substitute for construction materials like Ordinary Portland Cement since they carry enormous impact on the environment. This review presents the importance of geopolymeric materials and their role in sustainable development giving special emphasis to kaolin, metakaolin, zeolite, fly ash, dolomite, red mud and clay based geopolymer materials.
