All-steel-slag-based soft soil curing agent as well as preparation method and application thereof
The invention relates to a soft soil curing agent, in particular to an all-steel-slag-based soft soil curing agent as well as a preparation method and application thereof. Steel slag powder and an alkaline activator are subjected to dry mixing, then water is added for stirring, and ultrasonic cavitation is performed to obtain the all-steel-slag-based soft soil curing agent; the particle size of the steel slag powder is continuously distributed between 0.1 mu m and 200 mu m, the steel slag powder with the particle size smaller than 200 mu m accounts for 100%, and the steel slag powder with the particle size smaller than 26 mu m accounts for 50%. Compared with the prior art, the problems that in the prior art, a soft soil curing agent difficultly makes full use of steel slag powder and the requirement for the particle size of the steel slag powder is high are solved, development of the full-steel-slag-based soft soil curing agent is achieved, and large-particle-size steel slag powder can be utilized in the soft soil curing agent.
本发明涉及一种软土固化剂，具体涉及一种全钢渣基软土固化剂及其制备方法和应用，由钢渣粉与碱性激发剂干混后再加水搅拌并超声空化得到；所述的钢渣粉的粒径在0.1‑200μm之间连续分布，其中，粒径小于200μm的钢渣粉占比100%，粒径小于26μm的钢渣粉占比50%。与现有技术相比，本发明解决现有技术中软土固化剂对钢渣粉难以充分利用且对钢渣粉的粒径要求高的问题，本方案实现了全钢渣基软土固化剂的研制，并可在软土固化剂中利用大粒径钢渣粉。
