High-volume siliceous solid waste concrete activator and preparation method thereof
The invention discloses a high-volume siliceous solid waste concrete activator and a preparation method thereof, and belongs to the technical field of building material preparation. The high-volume siliceous solid waste concrete activator is prepared from the following raw materials in percentage by mass: 70 to 75 percent of carbide slag, 0.5 to 1.5 percent of sodium metasilicate, 0.2 to 1 percentof a water reducing agent, 0.1 to 0.5 percent of a dispersing agent and 20 to 30 percent of water. The high-volume siliceous solid waste concrete activator takes carbide slag as a main component, themain component of the carbide slag is calcium oxide, the content reaches 70% or above, calcium oxide powder is obtained by drying and grinding the carbide slag, so that the early-stage activity of siliceous solid waste is doped and activated, and meanwhile, when the doping amount of the carbide slag is controlled to be lower than 12% of the mass of cement, the early-stage breaking strength of thecement can be improved.
本发明公开了一种大掺量硅质固废混凝土活化剂及其制备方法，属于建筑材料制备技术领域。一种大掺量硅质固废混凝土活化剂，包括下述质量百分比的原料制成：电石渣70‑75%、偏硅酸钠0.5‑1.5%、减水剂0.2‑1%、分散剂0.1‑0.5%、水20‑30%。本发明一种大掺量硅质固废混凝土活化剂，主要成分为电石渣，电石渣主要成分为氧化钙，含量达到70%以上，通过对电石渣烘干和研磨处理得到氧化钙粉末，以此来掺入并活化硅质固废前期的活性，同时电石渣的掺入，控制其掺量低于水泥质量的12%时，可以提高水泥的早期抗折强度。
