Activating agent for reducing soaking expansion rate of steel slag as well as preparation method and use method of activating agent
The invention relates to the technical field of steel slag pretreatment, in particular to an activating agent for reducing the soaking expansion rate of steel slag and a preparation method and a using method of the activating agent. The activating agent is obtained by mixing a plant urease solution and a urea solution, and the soaking expansion rate of the steel slag is reduced by controlling the concentration and the adding volume proportion of the plant urease solution and the urea solution; the prepared activating agent can show a good effect of reducing the soaking expansion rate of the steel slag, the soaking expansion rate of the steel slag can reach 1.2% or below, and the volume expansion rate of a steel slag-asphalt mixture can reach 0.8% or below; when in use, the steel slag and the activating agent are directly soaked and activated, so that the activating time is shorter, a larger occupied area is not needed, the cost is lower, and popularization and application are facilitated.
本发明涉及了钢渣预处理技术领域，具体涉及了一种降低钢渣浸水膨胀率的活化剂及其制备、使用方法，该活化剂是包括植物脲酶溶液和尿素溶液混合得到的，通过控制植物脲酶溶液和尿素溶液的浓度以及添加体积比例，使得制备得到的活化剂能够表现出良好的降钢渣浸水膨胀率的效果，能够使钢渣浸水膨胀率达到1.2％以下，钢渣‑沥青混合料体积膨胀率达到0.8％以下；使用时，直接将钢渣和活化剂进行浸泡活化即可，活化时间较短，无需较大的占地面，成本较低，便于推广应用。
