Coal gangue slag cementing material and preparation method thereof
The invention discloses a coal gangue slag cementing material and a preparation method thereof.The coal gangue slag cementing material is prepared from 22 parts of coal gangue slag, 3 parts of activated emulsion, 5 parts of aluminum ammonium sulfate, 9 parts of water glass solution, 4 parts of KOH solid, 20 parts of high-activity red mud, 13 parts of sulfuric acid solution and 17 parts of grinding agent.The coal gangue slag is ground into fine powder, and then the coal gangue slag is ground to 100-170-mesh sieve; an activated emulsion accounting for 10-14% of the weight of the mixture is added into the coal gangue slag, and the activated emulsion is prepared by mixing the following raw materials in parts by weight: 7-10 parts of sodium fluosilicate, 0.1-0.2 part of sodium chloride, 0.1-0.2 part of sp-80, 1-2 parts of sodium carboxymethyl cellulose and 100-130 parts of deionized water. According to the coal gangue slag cementing material and the preparation method thereof, silicon gel and aluminum gel are adopted as main materials, so that the coal gangue slag cementing material has very high strength and construction performance, calcium stearate is added as a stabilizer to play a cementing role, and the strength of the gel is further improved, so that the coal gangue slag can be recycled, and the cost is reduced. By adding the high-activity red mud, the strength of the gel can be improved.
本发明公开了一种煤矸石矿渣胶凝材料及制备方法，包括煤矸石矿渣22份、活化乳液3份、硫酸铝铵5份、水玻璃溶液9份、KOH固体4份、高活性赤泥20份、硫酸溶液13份、助磨剂17份，所述煤矸石矿渣研磨成细粉，然后将煤矸石矿渣研磨至100‑170目筛，所述煤矸石矿渣中加入混合料重量10‑14%的活化乳液，所述活化乳液是由以下重量份的原料混合组成的：氟硅酸钠7‑10、氯化钠0.1‑0.2、sp‑800.1‑0.2、羧甲基纤维素钠1‑2、去离子水100‑130。该煤矸石矿渣胶凝材料及制备方法，通过采用硅、铝凝胶为主，具有很高的强度和施工性能，其中加入硬脂酸钙作为稳定剂，起到胶结的作用，进一步提高了凝胶的强度，从而使得煤矸石矿渣可以进行再利用，添加高活性赤泥可以提高凝胶的强度。
