Mix-enhanced binding gypsum and preparation method thereof
The invention discloses a mix-enhanced binding gypsum and a preparation method thereof. The binding gypsum comprises the following components in percentage by weight: 41-64% of desulfurized gypsum, 5-15% of light-weight powder, 23-40% of fine sand, 1-5% of organic binder, 1-5% of inorganic binder and 1-2% of retarder. The preparation method comprises the following steps: proportionally weighing the materials, sequentially putting into a mixing machine, and thoroughly mixing to obtain the mix-enhanced binding gypsum. The mix-enhanced binding gypsum has favorable binding strength and compression strength. The main raw material is the desulfurized gypsum, thereby opening up a new way for comprehensive utilization of industrial solid waste and achieving the dual effects of environmental protection and waste utilization. The mix-enhanced binding gypsum can greatly lower the production cost of the inorganic material, and is convenient for transportation. The mix-enhanced binding gypsum is simple in preparation technique and convenient for construction.
