Treatment method for inhibiting volume expansion of steel slag aggregate
The invention discloses a treatment method for inhibiting volume expansion of steel slag aggregate, and relates to the technical field of road engineering pavement material modification. According to the method, the organic separant is sprayed on the surfaces of the steel slag particles, and after the organic separant is sprayed, the inorganic modifier is added for dry mixing, so that the steel slag particles are treated. Wherein the organic separant is prepared from organic silicon resin and auxiliaries, and the inorganic modifier is composed of cement and silicon powder. A new membrane structure is formed on the surface of the treated steel slag, the probability of hydration reaction between water and the steel slag is reduced through the interface, and the volume stability of the steel slag is improved. The preparation method has the advantages that the cost is greatly reduced, the inhibition efficiency is greatly improved, the shedding phenomenon of the inorganic modifier is reduced, the agglomeration phenomenon of the organic modifier is solved, and the popularization value is good.
本发明公开了一种抑制钢渣集料体积膨胀处治方法，涉及道路工程路面材料改性技术领域。本发明通过在钢渣颗粒表面喷洒有机隔离剂，喷洒有机隔离剂后，添加无机改性剂进行干拌，对钢渣颗粒进行处理。其中，有机隔离剂由有机硅树脂和助剂配制而成，无机改性剂由水泥和硅粉组成。处理后的钢渣表面形成了新的膜结构，此界面阻止了水与钢渣发生水化反应的概率，提高了钢渣的体积稳定性。在降低成本、提高抑制效率方面得到大幅提升，并且减少了无机改性剂的脱落现象，解决了有机改性剂的团聚现象，具有良好的推广价值。
