Abstract:Geopolymer grouting material is a new kind of grouting material. The usage of coal gangue as raw material to prepare geopolymer grouting material can effectively solve the accumulation of coal gangue. Meanwhile, it can reduce the pollution of different grouting materials in the use and production process. These all make a great significance to the environment and resources. This review summarizes the research on coal gangue-based geopolymer grouting materials in recent years, introduces the selection of raw materials, preparation conditions and performance enhancement methods of coal gangue-based geopolymer grouting materials. The current problems of grouting materials are summarized and analyzed.
