Method for preparing concrete underground pipe gallery from graphite tailings
The invention discloses a method for preparing a concrete underground pipe gallery from graphite tailings. The concrete underground pipe gallery is prepared from 30-35 parts of Portland cement, 20-50parts of stone, 30-60 parts of sand, 20 to 35 parts of graphite tailings; 8 to 15 parts of a water reducing agent; 10 to 13 parts of polymethyl methacrylate, 26 to 40 parts of rubber emulsion, 8 to 13parts of a silane coupling agent, 12 to 16 parts of recycled textile fiber, 10 to 18 parts of fatty alcohol-polyoxyethylene ether, 6 to 13 parts of ethylene-vinyl acetate copolymer, 1 to 8 parts of hollow glass beads, 1 to 5 parts of Vaseline and 100 to 160 parts of water. The concrete underground pipe gallery prepared through the scheme has the advantages of being high in strength, low in waterpermeability and good in heat preservation effect, the graphite tailings and the textile fiber waste are fully utilized, waste resource recycling is achieved, and environmental pollution is reduced.
本发明公开了一种由石墨尾矿制备混凝土地下管廊的方法，所述的混凝土地下管廊由30‑35份硅酸盐水泥、20‑50份石子、30‑60份砂子、20‑35份石墨尾矿、8‑15份减水剂、聚甲基丙烯酸甲酯10‑13份、26‑40份橡胶乳液、8‑13份硅烷偶联剂、12‑16份回收纺织纤维、10‑18份脂肪醇聚氧乙烯醚、6‑13份乙烯‑醋酸乙烯共聚物、1‑8份空心玻璃微珠、1‑5份凡士林、水100‑160份制成。本发明方案制备混凝土地下管廊具有高强度、低渗水性及保温效果好的特点，充分利用石墨尾矿及纺织纤维废弃物，实现了废弃资源重复利用，降低环境污染。
