Cementing material as well as preparation method and application thereof
The invention discloses a cementing material as well as a preparation method and application thereof, and relates to the technical field of cementing materials. The cementing material is prepared from the following components in parts by mass: 10 to 30 parts of steel slag, 5 to 30 parts of roasting dedusting ash, 3 to 10 parts of desulfurized fly ash, 30 to 50 parts of slag and 5 to 10 parts of exciting agent. The gelling material can replace a traditional gelling material, a backfill body formed by the gelling material has high compressive strength and high anti-permeability performance, the compressive strength can reach 2-3 times that of cement under the condition of the same cement-sand ratio, the anti-permeability pressure is higher, namely, the anti-permeability performance is better, meanwhile, the leaching concentration of heavy metal ions is lower, the gelling material is more environmentally friendly, and the backfill body is suitable for large-scale popularization and application. The production cost can be reduced, the requirement of large-scale production can be met, and the method is suitable for filling materials and is applied to mine backfilling, especially backfilling of fine-fraction multi-metal tailings.
本发明公开了一种胶凝材料及其制备方法和应用，涉及胶凝材料技术领域。本发明的胶凝材料按质量份数计，包括如下组分：钢渣10～30份，焙烧除尘灰5～30份，脱硫灰3～10份，矿渣30～50份，激发剂5～10份。本发明的胶凝材料能够替代传统的胶凝材料，其形成的回填体具有高抗压强度和高抗渗性能，在相同灰砂比的条件下抗压强度可以达到水泥的2～3倍，且抗渗压力更高，即抗渗性能更好，同时重金属离子浸出浓度更低，对环境更友好，还能够降低生产成本且满足大规模生产的需求，适合用于充填材料，应用到矿山回填中，尤其是细粒级多金属尾矿的回填。
