Abstract

Desulfurization gypsum sand pulp belongs to construction materials. The desulfurization gypsum sand pulp comprises surface layer painting desulfurization gypsum and bottom layer painting desulfurization gypsum, wherein the surface layer painting desulfurization gypsum comprises 79.6 percent of desulfurization gypsum, 0.35 percent of SC calcium sulphate retarder, 20 percent of coal ash and 0.010 percent of cellulose ether according to weight percentage; the bottom layer painting desulfurization gypsum comprises 79.6 percent of desulfurization gypsum, 0.35 percent of SC calcium sulphate retarder, 20 percent of coal ash, 0.010 percent of cellulose ether and river sand, and the ratio of the mixture of the desulfurization gypsum, the SC calcium sulphate retarder, the coal ash and the cellulose ether to the sand is 1 to 2 according to weight percentage. The desulfurization gypsum sand pulp has the advantages that the desulfurization gypsum sand pulp mainly comprises industrial residue, is suitable for decorative surface plastering to a common clay tile wall, an air-ejecting concrete wall and the like under a dry environment, the desulfurization gypsum sand pulp can be produced in factory, and convenient and fast construction can be achieved. The working performance and the physical and mechanical properties are improved, and radioactivity, hazardous material and corrosion are avoided.

Description

technical field [0001] The invention relates to a building material, in particular to a desulfurized gypsum mortar. Background technique [0002] At present, the flue gas desulfurization used in the industry produces a large amount of industrial waste residue - desulfurization gypsum, stacking these industrial waste residue - desulfurization gypsum takes up a lot of land and fertile fields, and there is no good treatment method, which brings secondary pollution to our life , is also an environmental pollution problem that we urgently need to solve. Contents of the invention [0003] Technical problem: The purpose of this invention is to provide a desulfurized gypsum mortar, which uses industrial by-products to solve the problem of environmental pollution caused by industrial waste residues. [0004] Technical solution: the object of the present invention is achieved in this way: the desulfurized gypsum mortar includes two types of desulfurized gypsum on the surface layer ...
