Baking-free brick containing desulfurization slag and steel slag
The invention discloses a baking-free brick containing desulfurized slag and steel slag, which is prepared from the following materials by weight: 20-35% of desulfurized slag, 3-10% of fly ash, 5-20% of water-quenched slag powder, 5-15% of Portland cement and 20-50% of steel slag, and the desulfurized slag is a main solid waste filler and a volcanic ash activity excitation material. The desulfurization slag, fly ash, water-quenched slag powder, Portland cement and steel slag micro powder are used as curing cementing materials and exciting agents, and one or more of the materials can be combined to meet the requirements of cementing and curing strength and products. The invention relates to the technical field of construction materials, in particular to a baking-free brick containing desulfurization slag and steel slag. The instability influence of calcium sulfite, ettringite and steel slag is reduced, the stability of building materials using related raw materials is improved, and the possible expansion damage influence in the later period can be basically controlled by adding the volcanic ash material and controlling the particle size of the steel slag aggregate to be not larger than 3 mm; the alkalinity and the gelling property of the solid waste and dense filling of aggregate gradation are fully utilized, use of materials such as cement and gravel is reduced, and the cost is greatly reduced.
本发明公开了含脱硫渣及钢渣之免烧砖，由以下材料重量配比制成：脱硫渣20‑35％、粉煤灰3‑10％、水淬渣粉5‑20％、硅酸盐水泥5‑15％、钢渣20‑50％，其中脱硫渣为主要的固废填充料与火山灰活性激发材料。脱硫渣、粉煤灰、水淬渣粉、硅酸盐水泥、钢渣微粉为固化胶结料和激发剂，上述材料可一种或多种组合来达到胶结固化的强度与产品的要求。本发明涉及营建材料技术领域，具体涉及含脱硫渣及钢渣之免烧砖。降低亚硫酸钙、钙矾石和钢渣的不稳定性影响，提高使用相关原料之建材的安定性，添加火山灰材料及控制钢渣骨料粒径不大于3mm可基本上控制住后期可能的膨胀破坏影响；充分利用固废本身的碱性、胶凝性质和骨料级配的致密填充，减少使用如水泥、砂石等材料，大幅降低成本。
