Attapulgite pyroclastic rock concrete aggregate

Abstract

The invention discloses an attapulgite pyroclastic rock concrete aggregate. The key points of the technical scheme are as follows: the attapulgite pyroclastic rock concrete aggregate consists of attapulgite clay tailings, pyroclastic rock mixtures, construction wastes, opals and montmorillonite tailings. The ingredients of the attapulgite pyroclastic rock concrete aggregate are stirred uniformly to be crushed, screened and then packaged to be the finished the attapulgite pyroclastic rock concrete aggregate. The attapulgite pyroclastic rock concrete aggregate is taken as construction materials, low in processing cost and used for common concrete engineering, the needed technical equipment is simple, and the quality of the attapulgite pyroclastic rock concrete aggregate conforms to the related standard requirements; the most of ingredients of the attapulgite pyroclastic rock concrete aggregate adopt various wastes, so that not only can the resource utilization ratio be improved, the wastes are turned into wealth, but also the occupied space is reduced, the environment is protected and purified, the energy resources are saved, the production cost is lowered, the economical benefits are improved, and the attapulgite pyroclastic rock concrete aggregate is suitable for the common concrete engineering.

Description

technical field [0001] The invention relates to building materials, in particular to an attapulgite pyroclastic rock concrete aggregate. Background technique [0002] 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. [0003] In addition to attapulgite, attapulgite clay often contains minerals such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0004] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits. In some attapulgite clay deposits, the thickness of pyroclastic ro...

[0004]Pyroclastic rocks coexist with attapulgite clay deposits, and pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits, and some attapulgite clay deposits The thickness of the pyroclastic rock layer in the upper layer of the mining area is as high as tens of meters. During the mining process of the attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. According to field investigations, every ton of attapulgite clay mining Rodstone clay produces more than 30 tons of pyroclastic rocks. Calculated at an annual output of 150,000 tons, the pyroclastic rocks produced are as high as 4.5 million tons. They have not been utilized for many years, and the entire mining area is re-accumulated everywhere. Pyroclastic rock mixture, causing serious waste of resources and economic losses
