Molybdenum tailing concrete capable of replacing cement slurry and preparation method of molybdenum tailing concrete
The invention relates to molybdenum tailing concrete capable of replacing cement slurry and a preparation method of the molybdenum tailing concrete. The concrete is prepared from 216 to 240 kg of cement, 8.875 to 35.5 kg of molybdenum tailings, 620 kg of sand, 1445 kg of stones, 1.20 to 1.26 kg of a water reducing agent and 103.5 to 115.0 kg of water according to the weight per cubic meter. The preparation method comprises the steps of weighing the cement and the molybdenum tailings according to the ratio, uniformly stirring to form a cementing material, mixing the weighed water reducing agent with the cementing material, and uniformly stirring; sequentially adding the stones, the cementing material and the sand into the stirrer, and pouring into the stirrer for dry mixing; then adding water into the stirrer twice, and uniformly stirring the slurry to finish the preparation of the molybdenum tailing concrete mixture capable of replacing the cement slurry; vibrating the molybdenum tailing concrete mixture capable of replacing the cement slurry, and injecting into a mold to be formed; and finally, placing for demolding, and carrying out moisture-retaining curing on the formed molybdenum tailing concrete capable of replacing the cement slurry. According to the method, environmental pollution caused by tailing accumulation and tailing pond dam break can be reduced, waste utilization is achieved, and good economic and social significance is achieved.
一种替代水泥浆料钼尾矿混凝土及其制备方法，混凝土按每立方米重量计，由216～240kg水泥、8.875kg～35.5kg钼尾矿、620kg砂、1445kg石子、1.20～1.26kg减水剂和103.5～115.0kg水制成；制备方法是先将水泥、钼尾矿按所述配比称量材料，搅拌均匀组成胶凝材料，再将称量好的减水剂与胶凝材料混合，搅拌均匀；再依次向搅拌机中加入石子、胶凝材料和砂，倒入搅拌机中进行干拌；然后将水分两次加入搅拌机中，浆体搅拌均匀，替代水泥浆料钼尾矿混凝土拌合物制作完成；再将替代水泥浆料钼尾矿混凝土拌合物振捣后注入模具成型；最后放置进行脱模，将成型后的替代水泥浆料钼尾矿混凝土进行保潮养护；本发明可以减少尾矿堆积、尾矿库溃坝所造成的环境污染，实现废物利用，具有好的经济和社会意义。
