A Review of Microstructural and Mechanical Properties of Geopolymer Concrete

A safe disposal of huge amounts of industrial waste from different industries (wood industry, power generation industry, iron and steel industry, mining industry, rice grinding industry and other industries) is a major challenge in addition to the environmental and health damage caused by these wastes. The best way to get rid of this waste is to dispose of the waste. In recent years, the use of geopolymers has been used. The use of geopolymers in solving solid waste management problems of alumosilicate solid waste from various industries is also characterized by solving the ecological degradation problem regarding to utilize of OPC as a main bond in a construction manufacture. The outcome of modern studies indicate that geopolymer cement manufactured utilizing different by-product showed identical mechanical or physical properties and strength comparized with OPC concrete.
The present paper dealt with the brief review of previous studies on use of the industrial by-product as major bonding material within geological concrete manufacturing. The influence of key factors such as particle size distribution, strong environmental exposure to mechanical strength, use of chemical activator, physical properties, microstructure, post-processing system, and durability properties of geological concrete were also addressed. In addition, the current procedures for physical design, manufacturing and post-industrial processing have been thoroughly reviewed to determine the restrictions of present geopolymer technique in order to hinder their widespread application in the construction process. This review study also analyzed the microbiological structure of the geopolymer samples and the comparison of the geological polymers with the other bonding materials
