Abstract

Thanks to significant advances in mechanical development, the use of concrete has increased significantly in recent years, and the concrete industry generates about 1.35 billion tonnes of ozone depleting emissions each year, which is approximately 7% of all ozone depleting substances released into the environment. At the same time, thermal power plants generate a lot of fly ash that is not reused. This places a tremendous burden on effective waste management. As a result, a geopolymer innovation is one of the possible ways to limit CO2 emissions from the concrete industry and using fly ash effectively. In terms of harmful atmospheric degradation, geopolymer based fly ash actuated by soluble activators not only has the potential to reduce the carbon footprint of traditional Portland concrete cement, but also shows significant promise for applications in construction industry as an alternative to Portland cement. This article summarizes the current status of geopolymer adhesives and fly ash concrete, and reviews the most important research findings on various aspects of geopolymer concrete (GPB) in recent years. It also highlights important factors to consider when improving the performance of the GPC at elevated temperatures as well as at ambient temperatures.
