摘要：
Coal‑based solid waste geopolymer grouting materials were prepared with coal gangue and fly ash as the main cementitious components， desulfurized gypsum and alkali activator as ligands， with a small amount of admixtures.Twenty‑five sets of experiments were carried out by response surface method to find the quantitative relation among each index and every factor versus the optimal ratio of each factor level. The results show that the regression model and response surface established by the response surface method reflect well the degree of the influence of the modifier on the slurry performance. At the same time， the slurry ratio of the compound modifier can be optimized. Under the compound effect of modifier， the geopolymer grouting material prepared with large content of coal‑based solid waste has low viscosity and good fluidity. In addition， setting time， compressive strength and impermeability meet the requirements of mine grouting material， and has good engineering application effect. © 2022 Tongji University.
