Argillaceous refractory attapulgite volcaniclastic-rock aggregate sand

Abstract

The invention discloses argillaceous refractory attapulgite volcaniclastic-rock aggregate sand. The argillaceous refractory attapulgite volcaniclastic-rock aggregate sand in the technical scheme is mainly characterized by comprising highly-viscous attapulgite clay powder, attapulgite clay tailings, volcaniclastic rock mixture, bauxite tailings, coal gangue and montmorillonite tailings. A finished product of the argillaceous refractory attapulgite volcaniclastic-rock aggregate sand is obtained by uniformly stirring the ingredients, crushing, soaking, extruding, roasting, crushing, screening and packaging. The argillaceous refractory attapulgite volcaniclastic-rock aggregate sand has the advantages of high strength and capability of avoiding fragmentation, high-temperature deformation and softening. The argillaceous refractory attapulgite volcaniclastic-rock aggregate sand is made of a great quantity of various wastes, so that resource utilization rate is increased beneficially, the wastes turn into wealth, land occupation can be reduced, environmental protection and purification are achieved, energy is saved, production cost is lowered, and economic benefit is improved. The argillaceous refractory attapulgite volcaniclastic-rock aggregate sand is applicable to common refractory concrete engineering.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic clay refractory aggregate sand. Background technique [0002] Refractory materials are mainly made of clay, bauxite, silica, magnesite, dolomite and other natural ores after processing. [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 violation of regulations, which has caused great safety hazards in the tailings ponds and posed a serious threat to the property and life safety of people in surrounding areas. [0004] In addition to attapulgite, attapulgite clay often contains minerals such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0005] Pyroclastic rocks coexist with attapulgite clay deposits. ...

AI Technical Summary

Problems solved by technology

[0005] Pyroclastic rocks coexist with attapulgite clay deposits, and pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits, and some pyroclastic rock deposits in the upper layer of attapulgite clay deposits of The thickness is as high as tens of meters. During the mining process of attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. There are more than 30 tons of pyroclastic rocks. Calculated according to the annual output of 150,000 tons, the pyroclastic rocks produced are as high as 4.5 million tons, which have not been utilized for many years. The entire mining area is full of re-accumulated pyroclastic rock mixtures, causing severe resource waste and economic loss
