Curing agent for in-situ curing of high-water-content silt soft soil
The invention relates to a curing agent for in-situ curing of high-water-content silt soft soil, which is prepared from the following components in percentage by mass: 30 to 70 percent of sulphoaluminate cement, 20 to 60 percent of alkali-activated cementing material, 3 to 12 percent of magnesium cementing material and 0 to 0.1 percent of surfactant, through compounding of all the components, the problem of early strength development of cured sludge soil under the film-covering curing condition is solved, and then the problem that an existing curing agent cannot meet the field curing bearing capacity due to the huge difference between indoor curing strength and field curing effect is solved. The curing agent has the advantages of being high in curing strength, short in time, low in cost and stable in performance, for silt soft soil with the water content larger than 60%, the curing strength under the film covering curing condition is considered, the curing agent meets the in-situ curing requirement on site, and the bearing capacity of a soft soil foundation can be effectively improved.
本发明涉及一种用于原位固化高含水率淤泥软土的固化剂，该固化剂按质量百分比计，由硫铝酸盐水泥30％‑70％、碱激发胶凝材料20％‑60％、镁质胶凝材料3％‑12％和表面活性剂0‑0.1％组成；本发明通过各组分复配，解决了覆膜养护条件下固化淤泥土的早期强度发展问题，进而克服了现有的固化剂因为室内固化强度与现场固化效果的巨大差异从而无法满足现场固化承载力的问题。本发明的固化剂具有固化强度高、时间短、成本低、性能稳定的优点，对于含水率大于60％的淤泥软土，考虑覆膜养护条件下的固化强度，适用于现场的原位固化要求，可有效提高软土地基的承载力。
