Saltpetering-free metallurgical slag composite micro-powder cementing material as well as preparation method and application thereof
The invention relates to the technical field of building materials, in particular to a saltpetering-free metallurgical slag composite micro-powder cementing material as well as a preparation method and application thereof. The preparation method of the saltpetering-free metallurgical slag composite micro-powder cementing material comprises the following steps: carrying out first reaction on steel slag micro-powder and acid, then adding slag to carry out second reaction, and then adding a water glass solution to obtain the saltpetering-free metallurgical slag composite micro-powder cementing material. According to the preparation method of the saltpetering-free metallurgical slag composite micropowder cementing material, the condition that the steel slag is easy to saltpeter is improved, and the subsequent resource reutilization of the steel slag is facilitated. In the preparation method of the saltpetering-free metallurgical slag composite micro-powder cementing material, the strong base is used as an exciting agent, so that the release of the internal cementing activity of the steel slag is promoted, and the subsequent steel slag utilization field is widened.
本发明涉及建筑材料技术领域，具体涉及一种无泛碱冶金渣复合微粉胶凝材料及其制备方法和应用。一种无泛碱冶金渣复合微粉胶凝材料的制备方法，将钢渣微粉与酸进行第一反应，然后加入矿渣进行第二反应，再加入水玻璃溶液，得到所述的无泛碱冶金渣复合微粉胶凝材料。本发明中无泛碱冶金渣复合微粉胶凝材料的制备方法改善了钢渣易泛碱的情况，有利于后续钢渣资源化再利用。本发明无泛碱冶金渣复合微粉胶凝材料的制备方法中，使用强碱作激发剂，促进了钢渣内部胶凝活性的释放，拓宽后续钢渣利用领域。
