Low-carbon composite gelling curing agent for curing silt soft soil and curing method of low-carbon composite gelling curing agent
The invention discloses a low-carbon composite gelling curing agent for curing silt soft soil and a curing method of the low-carbon composite gelling curing agent. The low-carbon composite gelling curing agent comprises the following components in parts by mass: 30-60 parts of steel slag powder; 10 to 25 parts of slag powder; 5 to 20 parts of fly ash; 2-10 parts of desulfurized fly ash; 5 to 15 parts of slaked lime; 2 to 10 parts of a retarder; and 5-20 parts of an exciting agent. The invention relates to a method for curing silt soft soil by using a low-carbon composite gelling curing agent. The method comprises the following steps: 1) mixing the low-carbon composite gelling curing agent with water to obtain a pre-prepared slurry; and 2) mixing the pre-prepared slurry with the silt soft soil through a deep mixing pile method. Under the condition that cement is not used, the problem that existing silt soft soil is difficult to solidify is solved. And hydration and inorganic condensation polymerization are carried out at the same time through a synergistic gelling effect, so that the high-strength solidified soil is prepared.
本发明公开了一种固化淤泥软土的低碳复合胶凝固化剂及其固化方法，所述低碳复合胶凝固化剂按质量份数计包括以下组分：钢渣粉：30‑60份；矿渣粉：10‑25份；粉煤灰：5‑20份；脱硫灰：2‑10份；熟石灰：5‑15份；缓凝剂：2‑10份；激发剂：5‑20份。低碳复合胶凝固化剂固化淤泥软土的方法，包括以下步骤：1)将所述低碳复合胶凝固化剂与水混合获得预制浆体；2)通过深层搅拌桩法，将预制浆体与淤泥软土相混合。本发明可在不使用水泥的情况下，解决现有淤泥软土难固化的问题。通过协同胶凝作用，使水化与无机缩聚反应同时进行，制备了高强度的固化土。
