Inorganic composite conglutination powder and preparation method thereof

Abstract

The invention discloses inorganic composite conglutination powder. The inorganic composite conglutination powder comprises the following materials in parts by weight: 1.5-6 parts of sodium sulphate, 6-12 parts of cement, 27.4-61.2 parts of blast furnace slag micro powder, 9-15.3 parts of industrial waste gypsum, 6.1-12.7 parts of carbide slag, 2-8 parts of salty mud, 10-25 parts of coal ashes and 0.05-5 parts of additives. The preparation method of the inorganic composite conglutination powder comprises the following steps of: drying the materials by a dryer; conveying the dried materials to a ball mill by a conveyor belt for being grinded and storing the grinded materials in a material storage bin; and preparing the materials in proportion, conveying the prepared materials by the conveyor belt for being sufficiently mixed, and storing the mixed materials to an finished product storage bin. The inorganic composite conglutination powder is inverted on the basis of saving energy and reducing emission, and reducing the cost of domestic mine underground filling material, and is an inorganic conglutination material which adopts industrial solid waste as the main material. The inorganic composite conglutination powder has the advantages of being low in cost, extensive in application, resource-saving and energy-saving.

Description

technical field [0001] The invention belongs to the technical field of mineral filling inorganic gelling materials, and in particular relates to an inorganic composite cement powder and a preparation method thereof. Background technique [0002] There are three kinds of mineral filling cementing materials in the prior art, i.e. ordinary industrial cement, cement powder, and high-water quick-setting materials. The three materials have their own advantages and disadvantages. Among them, the glue-solid powder has outstanding advantages as the cementing material for tailings filling. The glue-solid powder is a kind of full water velocity gelled filling composite material, which can be widely used in mining goaf filling, and as a Due to its good water solidity, the filling in the mine can be solidified in a short period of time, and the support of the mine and goaf can be completed in a short period of time. However, the glue solid powder in the prior art has disadvantages such...
