Solid waste-based thin-layer masonry mortar as well as preparation method and use method thereof

The invention relates to the technical field of masonry mortar, and particularly discloses solid-waste-based thin-layer masonry mortar as well as a preparation method and a use method thereof. The concrete contains more than 98wt% of solid waste, and cellulose ether is added into the solid waste residue powder, so that the activity of each component in later use of the water granulated slag, the steel slag and the desulfurized gypsum can be improved, the viscosity of a system is increased, and the stability is improved; active components in the solid waste residue powder interact with cement, so that the gelling performance of the solid waste-based thin-layer masonry mortar is improved; by limiting the dosage of the raw materials, the early hydration speed of the solid waste micro powder is controlled, the coagulation time of a cementing material system is adjusted, all the components have a synergistic effect and supplement each other, and the mechanical strength and stability of the solid waste-based masonr
