Green cementing material for underground engineering backfill and preparation method of green cementing material
The invention belongs to research, development and application of underground engineering backfill materials, and relates to a green cementing material for underground engineering backfill, a preparation method of the green cementing material and a composite optimizer, and the green cementing material comprises the following components: Portland cement, a polycarboxylate superplasticizer, talcum powder and an excitant. The base material is prepared from the following components in parts by weight: 800 to 1000 parts of mineral powder, 5000 to 7000 parts of unground slag, 2000 to 4000 parts of fly ash, 320 to 400 parts of bentonite, 1600 to 2800 parts of coarse aggregate and 5000 to 8000 parts of fine aggregate. The green cementing material is prepared from the following components in parts by weight: 8500 to 10000 parts of base material; the content of the composite optimizer is 1000-1905 parts, and the content of the composite optimizer does not include 0; and 500 to 700 parts of water. According to the invention, a large amount of solid waste materials are recycled to prepare the green gelling backfill material, and the green gelling backfill material is used for backfill of urban underground engineering, so that the problem of environmental damage caused by solid waste stacking is solved.
本发明属于地下工程回填材料研发与应用，涉及一种用于地下工程回填的绿色胶凝材料及其制备方法，复合优化剂，包括以下组分：硅酸盐水泥、聚羧酸减水剂、滑石粉和激发剂。基体材料，按重量份计，包括以下组分：矿粉800‑1000份，未磨炉渣5000‑7000份，粉煤灰2000‑4000份，膨润土320‑400份，粗骨料1600‑2800份、细骨料5000‑8000份。绿色胶凝材料，按重量份计，包括以下组分：所述基体材料8500‑10000份；所述复合优化剂1000‑1905份，不包括0；水500‑700份。本发明拟通过将大宗固废材料回收利用，制备成绿色胶凝回填材料，用于城市地下工程回填，解决因固废堆放而造成的环境破坏。
