Steel slag early strength activating agent as well as preparation method and application thereof
The invention relates to the technical field of building materials, in particular to a steel slag early-strength activating agent and a preparation method and application thereof.Amorphous minerals are prepared through a special technology, gypsum and modified aluminum oxide slag powder are added for compounding, and the early-stage hydration activity of a steel slag-based cementing material is synergistically improved; the setting and hardening time of the steel slag-based cementing material is effectively controlled by adding the retarder, the working performance of the steel slag-based cementing material is ensured, and the steel slag early strength activating agent can also enable the steel slag-based cementing material to have excellent later mechanical properties.
本发明涉及建筑材料技术领域，尤其是涉及一种钢渣早强活化剂及其制备方法与应用，本发明通过特殊工艺制备一种非晶态矿物，并添加石膏和改性氧化铝渣粉进行复配，协同提高钢渣基胶凝材料的早期水化活性，通过添加缓凝剂有效控制钢渣基胶凝材料的凝结硬化时间，保证其工作性能，而且，本发明钢渣早强活化剂还能使钢渣基胶凝材料具有优异的后期力学性能。
