Gypsum-based self-leveling mortar and preparation method thereof

Abstract

The invention discloses a gypsum-based self-leveling mortar and a preparation method thereof, and belongs to the technical field of building materials, wherein the gypsum-based self-leveling mortar comprises the following components: 40%-50% of phosphorus building gypsum, 5%-15% of aluminate cement, 10%-20% of fly ash, 15%-30% of iron tailing sand, 0.03%-0.05% of a super absorbent resin, 0.2%-0.5%of a water reducing agent, 0.2%-0.5% of redispersible latex powder, 0.05%-0.15% of cellulose ether, and 0.005% to 0.01% of a defoaming agent. The iron tailing sand is used for replacing non-renewableriver sand, coal ash is used for replacing part of cement, and the problems that solid waste is accumulated, utilization of the solid waste is improved, and the environment is affected can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a gypsum-based self-leveling mortar prepared by using phosphorus building gypsum, iron tailings sand and fly ash and a preparation method thereof. Background technique [0002] With the rise of the construction industry in the world, a lot of research on building materials has been produced. At the same time, industrial solid waste has also increased significantly. With the increasing accumulation of industrial solid waste and the use of less and less non-renewable resources in construction, the demand for industrial solid waste to be used in building materials is also increasing. [0003] The main sources of industrial solid waste in daily production and life are: coal gangue produced by the coal industry; blast furnace slag, steel slag and red mud produced by the metallurgical industry; fly ash and slag produced by fuel power plants and urban central hea...
