Steel slag-red mud-cement-based composite mortar and preparation method thereof
The invention relates to the technical field of building engineering materials, and discloses steel slag-red mud-cement-based composite mortar and a preparation method thereof. The invention aims at solving the technical problems that in the prior art, landfill and stockpiling treatment of red mud and steel slag causes serious pollution to the ecological environment, and meanwhile, single doping of the steel slag can obviously reduce the mechanical property and durability of cement mortar in the field of gel materials. The concrete comprises the following components in percentage by weight: 16.25%-20% of Portland cement, 2.50%-4.38% of red mud, 2.50%-4.37% of fine steel slag and the balance of 75% of aggregate, the water-binder ratio of the steel slag-red mud-cement-based composite mortar is 0.5. The industrial solid waste steel slag is used for replacing cement and standard sand in the mortar, environmental pollution is reduced, the production cost of the mortar is reduced, meanwhile, the situation that natural sand resources are gradually in shortage is relieved, the grain composition of the mortar is improved, the potential hydration activity of the steel slag is stimulated by adding the red mud, and the mechanical property, durability and the like of the mortar are further improved.
本发明涉及建筑工程材料技术领域，公开了一种钢渣‑赤泥‑水泥基复合砂浆及其制备方法。旨在解决现有技术中赤泥以及钢渣的填埋和堆存处理，对生态环境造成严重的污染，同时解决了在凝胶材料领域，钢渣的单掺会显著降低水泥砂浆的力学性能和耐久性能的技术问题。本发明包括硅酸盐水泥16.25％～20％、赤泥2.50％～4.38％、细钢渣2.50％～4.37％，其余为骨料75％；钢渣‑赤泥‑水泥基复合砂浆的水胶比为0.5。本发明将工业固废钢渣替代砂浆中的水泥及标准砂，减少环境污染，降低砂浆的生产成本，同时缓解天然砂资源逐渐短缺的局面，改善砂浆的颗粒级配，通过添加赤泥，激发钢渣的潜在水化活性，进一步改善砂浆的力学性能、耐久性能等。
