Silty clay composite curing agent and silty clay curing method
The invention relates to the technical field of road engineering, and discloses a silty clay composite curing agent and a silty clay curing method, the silty clay composite curing agent comprises the following substance components by mass: 1.5-3 parts of calcium oxide; 1.5 to 3 parts of sodium silicate; 1.5 to 3 parts of sodium tripolyphosphate; 1-2 parts of calcium fluoride; and 0.5-1 part of calcium chloride. The shaping index of the powdery clay is not greater than 12; in the silty clay, the mass of particles with the particle size larger than 0.075 mm does not exceed 60% of the total mass of the silty clay. Compared with the prior art, the silty clay composite curing agent can greatly improve the curing strength and water stability of silty clay, and has good popularization and application value.
本发明涉及道路工程技术领域，公开了一种粉质黏土复合固化剂及粉质黏土固化方法，包括如下质量份的物质组分：氧化钙1.5‑3份；硅酸钠1.5‑3份；三聚磷酸钠1.5‑3份；氟化钙1‑2份；氯化钙0.5‑1份。本发明中粉质黏土的塑形指数不大于12；粉质黏土中，粒径大于0.075mm的颗粒质量不超过粉质黏土总质量的60％。与现有技术相比，本发明的粉质黏土复合固化剂能够大幅度提高粉质黏土固化强度及水稳性能、具有很好的推广应用价值。
