Preparation method of solid waste-based cementing material early strength auxiliary agent
The invention provides a method for preparing a cementing material early strength auxiliary agent by using industrial waste residues, the method specifically comprises the following steps: calcining desulfurized gypsum at 600-700 DEG C to obtain anhydrous desulfurized gypsum, and mixing the anhydrous desulfurized gypsum with dihydrate desulfurized gypsum to obtain mixed desulfurized gypsum; mixing materials such as slag, waste incineration fly ash, refining slag, mixed desulfurized gypsum, calcium aluminate cement and water, heating to react, drying, and grinding to obtain the early strength auxiliary agent. The early strength auxiliary agent can improve the early strength of the solid waste-based cementing material, has the characteristics of low cost, environmental protection and the like, and a new way is developed for synergistic utilization and synergism of industrial waste residues.
本发明提供了一种利用工业废渣制备胶凝材料早强助剂的方法，具体为：将脱硫石膏在600℃～700℃下煅烧得到无水脱硫石膏，再与二水脱硫石膏混合得到混合脱硫石膏；将矿渣、垃圾焚烧飞灰、精炼渣、混合脱硫石膏、铝酸钙水泥、水等物料混合后，加热反应，然后干燥、粉磨制成早强助剂。本发明的早强助剂能够提高固废基胶凝材料的早期强度，具有成本低、绿色环保等特点，为工业废渣协同利用和协同开拓了新途径。
