Problems solved by technology

However, during the mining process of coke gemstones, a large amount of coke gemstone tailings will be produced. The tailings have low alumina content and high iron oxide content, so they are not suitable for refractory materials, and there is no reasonable use at present.
Its storage occupies a large amount of land, which not only wastes resources but also destroys the ecological environment

Abstract

The invention relates to building ceramsite taking flint clay tailing as a raw material and a preparation method thereof. The building ceramsite is prepared from the raw materials in percentage by weight: 60%-80% of flint clay tailing, 20%-40% of pore forming agent, and additive accounting for 0.2wt%-1wt% of the total mass of the flint clay tailing and the pore forming agent. The building ceramsite has the characteristics of wide raw material source, light mass, high strength, high-strength building, simple production process, simple promotion and low production cost. The sintered product has excellent performance, low stacking density, high water absorption and high strength.

Description

technical field [0001] The invention relates to a building ceramsite and a preparation method thereof, in particular to a building ceramsite using coke gem tailings as a raw material and a preparation method thereof. Background technique [0002] Construction ceramsite is a kind of ceramsite currently used to replace gravel in concrete in the construction field. Its application has been well received by construction businesses and approved by consumers. As a new type of environmentally friendly and heat-insulating lightweight material, the product has outstanding features, such as light weight, high strength, small thermal conductivity, low water absorption, high temperature resistance, anti-aging, acid and alkali resistance, no radioactivity, environmental protection and energy saving, etc., so in Widely used in construction field. [0003] Burnt gemstone is a silicate mineral with a calcined alumina content of 40-50%, a compact structure and a smooth cross-section. It is ...
