摘要
针对超高水材料时常出现压缩泌水,影响使用效果等问题,研究了粉煤灰、粒化高炉矿渣粉、选铁尾矿砂等工业固废的性能,结合超高水材料的特点,开展大量实验,通过在超高水充填材料中掺入适量工业固废,改善超高水材料性能,实现工业固废综合利用的目的。
In view of the problems of compression bleeding and affecting the use effect of ultra-high water materials, the properties of industrial solid wastes such as fly ash, granulated blast furnace slag powder and iron tailings sand were studied. Combined with the characteristics of super-high water materials, a large number of experiments were carried out to improve the properties of super-high water materials and realize the comprehensive utilization of industrial solid wastes by adding appropriate amount of industrial solid wastes into super-high water filling materials.
