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 phe
