Abstract: Aiming at achieving the purpose of synergistic treatment of two solid wastes: fly ash and calcium carbide slag, the mixture of fly ash and cal-cium carbide slag was mixed into high water filling materials to study the effect of different mixture ratio of fly ash and calciumc arbide slag on the physical and mechanical properties of high water filling material. Calcium carbide slag was used as alkali activator of fly ash to stimulate pozzolanic characteristics of fly ash. The test results show that: under the same fly ash content, with the increase of calcium carbide slag content, the setting time of the high water filling material is prolonged, the dry and wet bulk density increase first and then decrease, while the water content is just opposite. The peak strength of high water filling materials increases first and then decrease. According to the analysis, the optimal content of fly ash is 20%, and the optimal content of carbide slag in fly ash is 5%. The physical and mechanical parameters of the modified high water filling material are very close to that of pure high water filling material, which not only improves the economy of high water filling material, but also enriches the utilization way of fly ash and carbide slag.
