Abstract:In the utilization of solar energy resources,the technology of photothermal conversion and heat storage is very important. Compared with chemical and latent heat storage technology,solid sensible heat storage technology has become the most important heat storage technology due to its advantages of simple preparation process,energy saving,environmental protection and long-term stability. Geopolymer concrete is an innovative green building material. Using industrial waste as raw material not only has the characteristics of low carbon and environmental protection,but also shows excellent high temperature resistance and heat storage performance,which can be used as one of the choices of heat storage modules in high temperature environment. In this paper,the application potential of geopolymer concrete in sensible heat storage is reviewed,and its transformation process under high temperature environment is summarized,which lays a foundation for solid heat storage technology. Finally,the heat storage characteristics and influencing factors are discussed and the prediction model of thermal conductivity of geopolymer concrete is proposed. hnology,and the application potential of geopolymer concrete in photothermal power generation technology is demonstrated.
