Filling cementing material suitable for cold regions as well as preparation method and application of filling cementing material
The invention discloses a filling cementing material suitable for a cold region and a preparation method and application thereof, and belongs to the technical field of mine filling materials. The filling cementing material suitable for the cold region comprises the following components in parts by mass: 70-80 parts of blast furnace slag micro powder, 20-30 parts of an alkali activator and 2-4 parts of additional calcium salt. The filling material suitable for the cold region comprises the filling cementing material suitable for the cold region, and further comprises aggregate, water and an additive. Most of the raw materials of the filling cementing material suitable for the cold region are solid waste materials, so that the filling cementing material with excellent performance at low temperature can be prepared while the solid waste materials are solved, and the requirements of mine filling in low-temperature regions are met.
一种适用于寒区的充填胶凝材料及其制备方法和应用，属于矿山充填材料技术领域。该适用于寒区的充填胶凝材料，按质量份计，包括以下组分：高炉矿渣微粉70～80份、碱激发剂20～30份、外加钙盐2～4份。适用于寒区的充填材料，包括上述适用于寒区的充填胶凝材料，还包括骨料、水和外加剂。该适用于寒区的充填胶凝材料大部分原料为固废材料，在解决固废材料的同时还可以制得低温下性能优异的充填胶凝材料，满足低温地区矿山充填的需要。
