Multi-source solid waste composite filling cementing material, preparation method thereof and filling material containing multi-source solid waste composite filling cementing material
The invention provides a multi-source solid waste composite filling cementing material, a preparation method thereof and a filling material containing the multi-source solid waste composite filling cementing material, and belongs to the field of building materials. According to the invention, sodium sulfate is utilized to modify gypsum separated and extracted from biological oxidation liquid, raw material components and proportion are reasonably designed, gypsum, water granulated slag, fly ash and other solid wastes are mixed, and the use cost of the cementing material is effectively reduced. The multi-source solid waste composite filling cementing material comprises the following raw materials in parts by weight: 15.5-20.5 parts of gypsum powder, 10-15 parts of sodium sulfate, 22.5-27.5 parts of water granulated slag micro powder, 22.5-27.5 parts of fly ash, 2.5-7.5 parts of cement clinker, 7.5-12.5 parts of quick lime and 0.5-2 parts of an active excitant, the cementing material contains more active components, the hydration speed is high, multiple hydration products are generated, the setting time is short, and the cementing material is suitable for large-scale production. And the filling material prepared from the material has high strength index.
本申请提供了一种多源固废复合充填胶凝材料及其制备方法和含有该材料的充填料，属于建筑材料领域。本申请利用硫酸钠对生物氧化液中分离提取的石膏进行改性，合理设计原料成分及配比，将石膏、水渣、粉煤灰等多种固废混合，有效降低了胶凝材料的使用成本。本申请提供的多源固废复合充填胶凝材料包括如下重量份数的原料：石膏粉15.5‑20.5份、硫酸钠10‑15份、水渣微粉22.5‑27.5份、粉煤灰22.5‑27.5份、水泥熟料2.5‑7.5份、生石灰7.5‑12.5份、活性激发剂0.5‑2份，该胶凝材料中含有较多活性成分，水化速度快、水化产物多、凝结时间短，采用其制备的充填料强度指标高。
