Sulfur-containing waste rock high-performance green concrete
The invention relates to the technical field of construction materials, and discloses a sulfur-containing waste rock high-performance green concrete, which comprises the following materials by weight: 25-55% of red mud, 0-15% of fly ash, 5-30% of water-quenched slag powder, 5-20% of carbide slag, 5-30% of Portland cement, 5-15% of sodium silicate, 0-10% of sodium hydroxide, 0-5% of gypsum, and 10-50% of filler and aggregate. The ratio can be determined to be proper according to conditions such as raw material properties, baking-free brick product strength requirements, local raw material supply conditions and the like. Wherein the red mud is a main solid waste filler and a langu material. The usage amount of concrete cement and water is low, and the volume stability and water tightness of the concrete are improved. According to the present invention, the water tightness and the self-healing ability of the crack filling are physically enhanced while the chemical reaction elements and the mechanism approach required by the ettringite generation are cut off, such that the internal sulfur-containing tailing material is not subjected to external erosion oxidation, and the volume stability, the durability and the environmental harmlessness of the concrete structure are ensured.
本发明涉及营建材料技术领域，公开了一种含硫废石的高性能绿色混凝土，混凝土材料重量配比范围如下：赤泥25‑55％，粉煤灰0‑15％，水淬渣粉5‑30％，电石渣5‑20％，硅酸盐水泥5‑30％，硅酸钠5‑15％，氢氧化钠0‑10％，石膏0‑5％，填充料及骨料10‑50％。以上配比可视原材料性质，免烧砖产品强度要求，当地原材料供给状况等条件，决定适当的配比。其中赤泥为主要的固废填充料与卜作岚材料。低混凝土水泥和水的使用量，增加混凝土的体积稳定性和水密性。断绝钙矾石生成所需的化学反应元素和机制途径，同时在物理上增强其水密性和裂缝填塞的自愈能力，确保内部含硫尾矿材料不受外部的侵蚀氧化，保证了混凝土结构的体积稳定性、耐久性与对环境的无害化。
