Non-burning attapulgite volcaniclastic-rock concrete aggregate sand

Abstract

The invention discloses non-burning attapulgite volcaniclastic-rock concrete aggregate sand, which is characterized by being composed of attapulgite clay tailings, a volcaniclastic-rock mixture, construction waste and opal and montmorillonite tailings. The components of the non-burning attapulgite volcaniclastic-rock concrete aggregate sand are uniformly stirred to be smashed and then are packaged into finished products of the non-burning attapulgite volcaniclastic-rock concrete aggregate sand. The non-burning attapulgite volcaniclastic-rock concrete aggregate sand is used as a construction material, and the needed technical equipment is simpler, the processing cost is low. The non-burning attapulgite volcaniclastic-rock concrete aggregate sand is used in ordinary concrete engineering, and the quality conforms to the relative standard. The components of the non-burning attapulgite volcaniclastic-rock concrete aggregate sand adopt a lot of various wastes, so that the resource utilization rate is increased, the wastes are changed into things of value, the occupied land can also be reduced, the environment can be protected and purified, the energy source is saved, and the production cost is reduced. The non-burning attapulgite volcaniclastic-rock concrete aggregate sand is suitable for concrete engineering.

Description

technical field [0001] The invention relates to building materials, in particular to a non-burning attapulgite pyroclastic rock concrete aggregate sand. 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 o...

Problems solved by technology

[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 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 mined There are more than 30 tons of pyroclastic rocks produced by stone clay. Based on the 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 full of redeposited volcanoes. Clastic rock mixture, causing serious waste of resources and economic losses
