The invention discloses an inorganic binding material prepared through classified treatment of building solid waste recycled aggregate and a preparation method of the inorganic binding material. The building solid waste recycled aggregate is taken as aggregate for producing inorganic binding material products with different strength. By means of a technology, an inorganic binding material stabilizing material is produced from building solid waste with processes of sorting, pre-wetting, impurity removal, crushing, sieving, secondary prewetting, storage, batching and stirring. By means of the technology for disposing the building solid waste, waste bricks and concrete in the building solid waste are converted into recycled aggregate through a specific processing procedure with sufficiently studied characteristics of the building solid waste, and inorganic binding material stabilized building solid waste recycled aggregate products are formed in cooperation with an inorganic binding material by plant mix, blending and stabilizing; a manual soring platform is fixed on a sieving equipment main body, large light substances are manually picked out, tiny particles and light substances areremoved through an air separation device, and impurity ingredients in the building solid waste are effectively removed.
