Curing agent for curing aeolian sand, method for curing aeolian sand and aeolian sand subbase

The invention discloses a curing agent for curing aeolian sand, a method for curing aeolian sand and an aeolian sand subbase. The curing agent consists of the following components: fly ash, lime, gypsum, an activator, a crosslinking agent A and a reinforcing material. B. The application of the curing agent in the aeolian sand subbase is the step of mixing the curing agent and water into the aeolian sand to serve as a material. Through analyzing the chemical properties of the fly ash, the first-grade fly ash of a power plant in Inner Mongolia is used as a main raw material, a third-grade quicklime is added, and then the high-strength gypsum, the activator NaOH, the cross-linking agent A and the reinforcing material B are added; the dosage of the fly ash is controlled at 60%; through changing the dosages of the other materials, the unconfined compressive strength is measured through a cement mortar test method; and through comparison and analysis, the final matching ratio of the added materials is determined, a
