ABSTRACT

Silicate cement is a cementitious material with high energy consumption, high pollution and huge resource consumption. During the cement production process, a large amount of carbon dioxide is emitted, causing serious climate anomalies. In order to reduce the amount of cement, a large number of industrial byproducts are widely used in commercial concrete, partially or completely replacing cement. The geopolymer concrete, which replaces cement with industrial by-products such as mineral powder and fly ash as concrete cementing material, has advantages in terms of low emissions and high strength, so cement-free concrete with geopolymer as the substrate was born. In this paper, based on the analysis of the current status of the research on geopolymer concrete, the main reaction mechanism of geopolymer concrete is further investigated, and the application and development trend of geopolymer concrete is studied with this guidance. The aim is to promote the research and development of green concrete as a contribution to the global environmental protection cause.
