Preparation method of gelling material based on electrolytic manganese residues
The invention provides a preparation method of a cementing material based on electrolytic manganese residues, which comprises the following steps: drying and grinding the electrolytic manganese residues, sieving with a 200-mesh sieve to obtain sieved electrolytic manganese residues, adding coke powder, uniformly mixing, calcining at 900 DEG C for 2 hours, naturally cooling, and sieving with the 200-mesh sieve to obtain calcined electrolytic manganese residues; naOH solid is dissolved in water, and a NaOH solution is obtained; uniformly mixing blast furnace slag, fly ash and calcined electrolytic manganese slag to obtain a mixture, then adding a NaOH solution, and uniformly stirring to obtain a cementing material slurry; and pouring the mixture into a 40 * 40 * 160mm mold, vibrating uniformly, and maintaining for 28 days to obtain the cementing material based on the electrolytic manganese residues. The raw materials used in the invention are solid waste materials, so that the consumption of the solid waste materials is increased; the gelling activity of the electrolytic manganese residues is improved through high-temperature calcination of the electrolytic manganese residues, and the performance of the gelling material is enhanced through the synergistic effect among the electrolytic manganese residues, the blast furnace slag and the fly ash.
本发明提供了一种基于电解锰渣的胶凝材料制备方法,该方法为:将电解锰渣烘干、研磨后,过200目筛,得到过筛后的电解锰渣,加入焦炭粉,混合均匀后,在900℃下煅烧2h,自然冷却,过200目筛,得到煅烧后的电解锰渣;将NaOH固体用水中溶解,得到NaOH溶液;将高炉矿渣、粉煤灰和煅烧后的电解锰渣混合均匀,得到混合料,然后加入NaOH溶液,搅拌均匀,得到胶凝材料浆体;倒入40×40×160mm的模具中,振捣均匀后,养护28d,得到基于电解锰渣的胶凝材料。本发明所用的原材均为固废材料,增大了固废材料的消耗;高温煅烧电解锰渣增高了电解锰渣的胶凝活性,电解锰渣、高炉矿渣和粉煤灰之间存在协同作用,增强了胶凝材料的性能。
