Application of ground powder of secondary aluminum ash high-temperature sintered slag and quick-hardening high-strength sulphoaluminate cement-based grouting material containing powder
The invention provides application of secondary aluminum ash high-temperature sintered slag ground powder and quick-hardening and high-strength sulphoaluminate cement-based grouting material containing the powder, secondary aluminum ash, heavy-related sludge and building muck are mixed and then subjected to drying and high-temperature treatment to obtain sintered slag, the sintered slag is ground to obtain the ground powder with the average particle size being 10-70 microns, and the ground powder is subjected to high-temperature treatment to obtain the quick-hardening and high-strength sulphoaluminate cement-based grouting material with the high-strength sulphoaluminate cement-based grouting material with the high-strength sulphoaluminate cement-based grouting material. The ground powder is added into the sulphoaluminate cement (SAC) grouting material, the method for preparing the grouting material from hazardous waste and harmful resources is provided, and the grouting material is good in mechanical property, working performance and environment friendliness and has high commercial value and popularization value.
本发明提供了二次铝灰高温烧结渣料磨细粉体的应用和含有该粉体的快硬高强硫铝酸盐水泥基注浆料，本发明将二次铝灰与涉重污泥及建筑渣土混合后经过烘干以及高温处理后得到烧结渣料，研磨得到平均粒径为10‑70μm磨细粉体，将所述磨细粉体添加到硫铝酸盐水泥(SAC)注浆料中，提供了一种利用危险废物有害资源制备得到注浆料的方法，且该注浆料力学性能、工作性能以及环境友好性好，具有较高的商业价值与推广价值。
