Soft soil foundation curing agent and construction method for curing soft soil foundation
The invention discloses a soft soil foundation curing agent and a construction method for curing a soft soil foundation. The curing agent comprises the following raw materials in percentage by mass: 40.1%-60.0% of carbonated steel slag, 4.2%-5.8% of slag powder and 34.2%-54.1% of cement. When the sum of the mass of the soft soil, the mass of the water and the mass of the soft soil curing agent is 100%, the doping ratio of the soft soil curing agent is 12.0-20.0%. The preparation method comprises the following steps: (1) preparation of soft soil foundation curing agent slurry: weighing carbonated steel slag, slag powder and cement according to a ratio, putting into a sample preparation barrel, fully mixing, adding water according to a water-cement ratio of 0.45-0.55, and stirring to prepare the soft soil foundation curing agent slurry. The carbonated steel slag and the slag powder are used for replacing a cement curing agent, the soft soil curing agent for fixing the soft soil foundation is prepared, the soft soil foundation is cured, and the strength of a cured pile body meets the design requirement. The problem of utilization of metallurgical industry solid waste is solved, and the problem of treatment of soft soil foundations in urban development and construction is also solved.
本发明公开了一种软土地基固化剂及用于固化软土地基的施工方法，固化剂原料中各组份的质量百分含量为：碳酸化钢渣40.1％～60.0％，矿渣粉4.2％～5.8％，水泥34.2％～54.1％。软土、水和软土固化剂质量之和按照100％计时，软土固化剂的掺入比为12.0～20.0％；(1)软土地基固化剂浆液的制备：按配比称取碳酸化钢渣、矿渣粉、水泥置于配样桶中，充分混合，然后按照0.45～0.55水灰比掺水，搅拌制成软土地基固化剂浆液。本发明利用碳酸化钢渣和矿渣粉代替水泥固化剂，制成固定软土地基的软土固化剂，固化软土地基，固化后的桩身强度均满足设计要求。不仅解决冶金工业固废的利用问题，也解决了城市发展建设中软土地基的处理问题。
