Tough geopolymer curing material for improving performance of silt soft soil and preparation method of tough geopolymer curing material
The invention relates to a tough geopolymer curing material for improving the performance of silt soft soil and a preparation method, the tough geopolymer curing material is used as a soil curing agent for improving the performance of the silt soft soil, and when the silt soft soil accounts for 480-600 parts by mass, the tough geopolymer curing material comprises the following components in parts by mass: 120-150 parts of slag, 200-240 parts of fly ash and 2-10 parts of polyacrylonitrile fiber. 120 to 140 parts of an alkaline activator and 150 to 170 parts of water; the slag and the fly ash are used as main raw materials, under the excitation condition, generation of an N-A-S-H gel phase, a C-S-H gel phase or an S-A-H gel phase is promoted, the mechanical property of a geopolymer is enhanced, meanwhile, a proper mixing amount of polyacrylonitrile fiber is added, the toughness of the geopolymer improved sludge solidified soil can be enhanced, and compared with Portland cement, the cement has the advantages of being low in cost, easy to obtain, low in cost and the like. And the preparation process is simple, low in cost, non-toxic and pollution-free.
本发明涉及一种改良淤泥软土性能的韧性地聚物固化材料及制备方法，其作为土壤固化剂对淤泥软土性能进行改良，当淤泥软土的质量份数为480‑600份时，包括按照重量计的以下组分及质量份数：矿渣120‑150份，粉煤灰200‑240份，聚丙烯腈纤维2‑10份，碱性激发剂120‑140份，水150‑170份；本发明以矿渣和粉煤灰为主要原料，在激发条件下，促进生成N‑A‑S‑H凝胶相、C‑S‑H凝胶相或S‑A‑H凝胶相，增强其地聚物的力学性能，同时加入合适掺量的聚丙烯腈纤维可增强地聚物改良淤泥固化土的韧性，相较于硅酸盐水泥，具有价廉易得，制备工艺简单，成本低，无毒无污染的特点。
