Embodiment Construction

[0026] Below in conjunction with embodiment the present invention will be further described:

[0027] 1. The ingredients of non-burning cylindrical attapulgite refractory ceramsite are composed of the following components by weight percentage: high-viscosity attapulgite clay powder 4%, attapulgite clay tailings powder 18%, granulated blast furnace slag 30%, powder Iron tailings powder 12%, coal gangue powder 10%, bauxite tailings powder 6%, diatomite tailings powder 4% and aluminate cement 16%.

[0028] 2. The production method of non-burning cylindrical attapulgite refractory ceramsite: (1) Add the ingredients of non-burning cylindrical attapulgite refractory ceramsite into the mixer and mix them, and then input them into the extrusion granulator for granulation. The particle diameter is controlled at 16 mm. The length is controlled at 25-35 mm; (2) The granulated particles are transported to the concrete curing room for routine curing of cement products for 28 days, and afte...

Abstract

The invention discloses baking-free cylindrical attapulgite fire-retarding ceramsite. The key point of the technical scheme is that the baking-free cylindrical attapulgite fire-retarding ceramsite consists of high-viscosity attapulgite clay powder, attapulgite clay tailing powder, granulated blast-furnace slag powder, iron tailing powder, coal gangue powder, bauxite tailing powder, kieselguhr tailing powder and aluminate cement. The baking-free cylindrical attapulgite fire-retarding ceramsite is produced by the following steps of mixing the ingredients, granulating, maintaining, sieving and packaging. The baking-free cylindrical attapulgite fire-retarding ceramsite has a rough and hard surface, and is high in compression strength, low in heat conductivity, high in refractoriness and corrosion resistance and good in heat-preserving and sound-insulating effect; and a large amount of fine pores are formed in the ceramsite,. The baking-free cylindrical attapulgite fire-retarding ceramsiteis produced by utilizing multiple tailings comprehensively, so that the utilization rate of resources is improved, waste materials are changed into wealth, and environment is protected. Besides, the baking-free cylindrical attapulgite fire-retarding ceramsite is suitable for producing fire-retarding ceramsite concrete and heat-preserving and sound-insulating materials.

Description

technical field [0001] The invention relates to ceramsite, in particular to an unfired cylindrical 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 beyon...
