Gravel-shaped attapulgite fireproof ceramsite

Abstract

The invention discloses a gravel-shaped attapulgite fireproof ceramsite. The key points of the technical scheme are as follows: the gravel-shaped attapulgite fireproof ceramsite is composed of high-viscosity attapulgite clay powder, attapulgite clay tailing powder, granulated blast furnace slag powder, iron tailing powder, coal gangue powder, bauxite tailing powder and diatomite tailing powder. After ingredients of the gravel-shaped attapulgite fireproof ceramsite are mixed, granulated, baked, cooled, crushed and screened, the obtained product is packaged to obtain the gravel-shaped attapulgite fireproof ceramsite. The gravel-shaped attapulgite fireproof ceramsite is a grain with an irregular shape and the grain is internally provided with a plurality of small air holes; and the gravel-shaped attapulgite fireproof ceramsite is the fireproof ceramsite which has the advantages of light weight, strong compressive strength, low coefficient of heat conductivity, high refractoriness, stablechemical performance, and good corrosion resistance and heat-preservation and sound-proof effects. The gravel-shaped attapulgite fireproof ceramsite can be produced by comprehensively utilizing a plurality of types of the tailings, so that the gravel-shaped attapulgite fireproof ceramsite is good for improving the resource utilization rate, changing wastes to valuable things, and protecting the environment; and the gravel-shaped attapulgite fireproof ceramsite is applicable to producing fireproof ceramsite concrete and heat-preservation and sound-proof materials.

Description

technical field [0001] The invention relates to ceramsite, in particular to a gravel-shaped attapulgite refractory ceramsite. Background technique [0002] Refractory concrete is a special concrete that can withstand high temperature and maintain the required physical and mechanical properties at high temperature. It is formulated with appropriate cementitious materials, refractory aggregates, admixtures and water in a certain proportion. [0003] Most of the refractory aggregates are heavy slag, crushed refractory bricks, basalt, bauxite clinker, sintered magnesia, etc. [0004] Coal gangue is discarded and occupies a large area of ​​land. The escape or leaching of sulfide in coal gangue will pollute the atmosphere, farmland and water bodies. [0005] 80% of my country's mineral resources are associated mines, a large amount of valuable resources are stored in tailings, and tailings stockpiles require a large amount of land. Many tailings ponds have been used beyond the t...

Problems solved by technology

[0007] The above-mentioned patent is to use boron mud, magnesium slag and binder as raw materials to produce refractory ceramsite. The disadvantage is that the refractory performance of these raw materials is not very good. It is difficult for ceramsite to meet the quality standards of refractory ceramsite
