High-mixing-amount concrete activating agent and preparation method thereof
The invention discloses a high-mixing-amount concrete activating agent and a preparation method thereof, and belongs to the technical field of building materials. The high-mixing-amount concrete activating agent is prepared from the following raw materials by weight percentage: 30-40% of alkaline residue, 15-25% of an ammonium nitrate solution, 10-20% of quartz sand tailings, 10-20% of gypsum and15-25% of a reinforcing agent. The invention has the beneficial effects that: the setting and hardening of the high-mixing-amount slag concrete are accelerated, so that the setting time and early strength of the high-mixing-amount slag concrete are similar to those of common concrete, and the construction is convenient. Compared with the conventional methods like mechanical activation and chemicalexcitation, the method avoids excessive energy consumption, and also avoids side effects on later performance. The raw materials are mostly solid waste materials, and a new channel is provided for development and utilization of solid waste.
本发明公开了一种高掺量混凝土活化剂及其制备方法，属于建筑材料技术领域。一种高掺量混凝土活化剂，它是由下述重量百分比的原料制成：碱渣30‑40%、硝酸铵溶液15‑25%、石英砂尾矿10‑20%、生石膏10‑20%、增强剂15‑25%。本发明的有益效果在于：加速大掺量矿渣混凝土凝结硬化，使它的凝结时间、早期强度与普通混凝土差不多，方便施工。与以往的机械活化和化学激发等方法相比较，既避免了多余的能量消耗，又避免了对后期性能的副作用。原材料多采用固废材料，对固废的开发利用提供了新的渠道。
