Abstract Mine grouting reinforcement and water plugging projects often require large amounts of grouting materials. To
reduce the carbon emission of grouting material production, improve the utilization of solid waste from mining
enterprises, and meet the needs of mine reinforcement and seepage control, a double-liquid grouting material
containing a high admixture of coal gangue powder/bottom ash geopolymer was studied. The setting time, fluidity, bleeding rate, and mechanical properties of grouting materials were studied through laboratory tests, and SEM
analyzed the microstructure of the materials. The results show that the total mixture of calcined gangue does not
exceed 60%. And the proportion… More >
