Cylindrical attapulgite construction waste ceramsite

Abstract

The invention discloses a cylindrical attapulgite construction waste ceramsite. The key point of the technical scheme is as follows: the cylindrical attapulgite construction waste ceramsite comprises high viscosity attapulgite clay powder, attapulgite clay tailing powder, construction waste powder, red bentonite powder, diatomite tailing powder and wood chip powder. The ingredients of the cylindrical attapulgite construction waste ceramsite are mixed, granulated, roasted, cooled, screened and packaged to obtain the cylindrical attapulgite construction waste ceramsite. The cylindrical attapulgite construction waste ceramsite is of cylindrical shape, has rough and hard surface and has a lot of fine pores in the interior; and the spherical attapulgite refractory ceramsite is a construction ceramsite with light weight, high strength, low thermal conductivity, high refractoriness, stable chemical property, durability and good heat insulation and sound insulation effect. The comprehensive utilization of construction wastes and tailings in producing the cylindrical attapulgite construction waste ceramsite is beneficial for increasing the resource utilization rate, turning waste into wealth and protecting the environment; and the cylindrical attapulgite construction waste ceramsite disclosed by the invention is suitable for producing ceramsite concrete as well as heat insulation and sound insulation materials.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cylindrical attapulgite construction waste ceramsite. Background technique [0002] Construction waste refers to the waste generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. The components of construction waste include: scattered mortar and concrete, broken bricks and broken concrete blocks, yellow sand, stones, block stones, muck, scrap steel bars, scrap iron wires, various scrap steel fittings, metal pipeline scrap, scrap Packing boxes and bags of bamboo wood, wood chips, shavings, various decorative materials, etc. [0003] 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 time limit or overloaded, or even operated in...

Problems solved by technology

[0005] The above-mentioned patent uses bricks and tiles, sandstone, decorative ceramic tiles, glass fragments, miscellaneous soil and waste straw as raw materials to produce porous ceramsite for construction waste. The disadvantage is that the bonding performance of these materials is relatively poor. Difficult, the strength of the finished ceramsite is small, it is difficult to meet the quality standard of building ceramsite
