Slit burning-free bricks and production method thereof

Abstract

The invention discloses slit burning-free bricks and a production method thereof. The slit burning-free bricks are produced by using the following raw materials in part by weight: 500 to 540 parts of dried slit, 236 to 240 parts of carbide slag, 150 to 170 parts of scrap, 68 to 70 parts of electric furnace slag, 16 to 17 parts of alumen, 68 to 7 parts of cement and 80 to 90 parts of water. The slit burning-free bricks are produced by the following steps: dewatering, drying slit, adding the carbide slag into the dried slit, uniformly mixing, piling, turning, deodorizing and sterilizing; adding other raw materials, slit and carbide slag into a mixer in turn and uniformly mixing; and forming by extruding the mixture, and curing to obtain the finished slit burning-free bricks. In the invention, the carbide slag is used to sterilize and disinfect the slit; the slit is deodorized by piling and turning; the quality of the product slit burning-free bricks reaches a standard, and the cost is low; and the social benefit of saving energy, protecting farm land and optimizing water environment is created.

Description

technical field [0001] The present invention relates to bricks or blocks for buildings. Background technique [0002] my country's traditional brick-making technology is to use clay to fire bricks. This technology has the following disadvantages: 1. Destruction of cultivated land. my country's production of solid clay bricks consumes more than one billion cubic meters of clay resources every year, which is equivalent to destroying 500,000 mu of land; 2. Consumption of a large amount of coal resources. According to incomplete statistics, my country consumes more than 70 million tons of standard coal each year due to the production of clay bricks; 3. Pollution to the environment. A lot of carbon dioxide is released into the air. [0003] Since 2000, solid clay bricks have been banned by the state because of their energy consumption, land damage and environmental pollution. According to the "Notice on Further Promoting Wall Material Innovation and Promotion of...

[0006] The technology of using sludge as the main raw material to prepare unburned bricks has solved the dual problems of sludge utilization and energy saving, but the research on this technology is still in its infancy, and the main difficulty is that the quality of unburned bricks obtained meets the requirements. Less than the standard of use, such as compressive strength, impermeability, frost resistance, etc.

The patent document with the application number 200810143622.4 introduces a non-fired silt brick with silt, sand and cement as the main materials and potassium permanganate as the auxiliary material. However, the document does not provide the performance of the obtained non-fired silt brick. Test data or beneficial technical effects
