High-activity admixture prepared from high-aluminum slag powder and preparation method of high-activity admixture
The invention discloses a high-activity admixture prepared from high-aluminum slag powder and a preparation method of the high-activity admixture. The high-activity admixture is prepared from the following components in percentage by weight: 60-82% of slag powder, 10-30% of silicon-calcium slag, 5-10% of desulfurized gypsum and 2-8% of an active synergist. The technical problem that unutilized furnace bottom slag can only be discharged to a solid waste storage yard, and huge pollution is caused to the environment is solved. The activity of the slag powder is greatly improved through mechanical activation and chemical activation, a way is developed for improving the additional value of the slag powder, and the big problem that the slag is difficult to treat is solved; the solid waste material is used for exciting the slag powder, so that the purpose of treating waste with waste is achieved. In the concrete production process, the cement consumption can be further reduced, the production cost is reduced, and the concrete quality is improved.
本发明公开了一种利用高铝炉渣粉制备的高活性掺合料及其制备方法，包括以下重量百分比的组分：炉渣粉60~82%，硅钙渣10~30%，脱硫石膏5~10%、活性增效剂2~8%。解决了未利用的炉底渣只能排放到固废堆场，给环境造成巨大污染的技术问题。本发明通过机械活化和化学活化大幅提高炉渣粉的活性，为提高其附加值开辟途径，解决炉渣难处理的大难题；利用固废材料对炉渣粉进行激发，达到以废治废的目的。在混凝土生产过程中，可进一步降低水泥用量，降低生产成本，提升混凝土质量。
