Fluidized soil for backfilling side wall of foundation pit and preparation method of fluidized soil
The invention discloses fluidized soil for foundation pit side wall backfilling and a preparation method thereof, and belongs to the technical field of fluidized soil preparation, the particle size of steel slag is smaller than 4 mm, the particle size of muck is smaller than 2 mm, cement is ordinary Portland P.O32.5 cement, and according to the mass ratio, water mass/(cement mass + steel slag mass + muck mass) is 62%, steel slag mass/(cement mass + steel slag mass) is 50%-66.7%, and water mass/(cement mass + steel slag mass) is 50%-66.7%. According to the method, the raw materials of the curing agent are selected and the mixing ratio is optimized, so that the cured muck has the backfill material condition, the method treats waste with waste, a muck field treatment idea is provided, and the method is suitable for large-scale popularization and application. The steel slag is used for replacing part of cement to solidify the muck, so that the use of cement materials can be reduced, and good strength development characteristics and permeability are shown by utilizing the cement and the steel slag to solidify the muck.
本发明公开了一种用于基坑侧壁回填流动化土及其制备方法，属于流动化土制备技术领域，钢渣粒径小于4mm，渣土粒径小于2mm，水泥为普通硅酸盐P.O32.5水泥，按质量比，水质量/(水泥质量+钢渣质量+渣土质量)＝62％，钢渣质量/(水泥质量+钢渣质量)＝50％‑66.7％，混合搅拌3～5min，养护7天即可作为现场基坑侧壁回填的材料使用，本发明通过对固化剂原料的选取以及配合比优化，使固化后的渣土具备回填材料条件，该方法以废治废，提供一种渣土现场处理的思路，使用钢渣替代部分水泥对渣土固化可减少水泥材料的使用，且利用水泥和钢渣固化渣土表现出良好的强度发展特性和渗透性。
