Mill tailing air-entraining brick

Abstract

The invention discloses a mill tailing air-entraining brick. The mill tailing air-entraining brick is composed of the following raw materials of, by weight, 0.8-2 parts of molybdenum oxide, 0.1-0.2 part of titanous sulfate, 4-6 parts of sea-foam stone powder, 10-20 parts of mill tailings, 1-2 parts of potassium zirconium carbonate, 0.1-0.4 part of dimethylethanolamine, 2-3 parts of bone charcoal, 2-3 parts of high-boron calcium borate, 4-6 parts of celestite powder, 2-3 parts of volcanic ash, 0.2-0.4 part of aluminum sulfate, 260-300 parts of pulverized coal, 42-46 parts of quick lime, 0.3-0.5 part of aluminum powder, 37-40 parts of ordinary portland cement and 5-10 parts of a biomass resistance enhancement agent. According to the mill tailing air-entraining brick, the biomass resistance enhancement agent is added, waste resource barks and coconut shells are adopted as biomass raw powder, after enzyme treatment and alkali treatment, fiber materials with good pliability can be obtained, the fiber materials are blended with methylacrylic acid glycidyl ester and subjected to modification, the surface resistance is improved, then the modified substance is mixed with saline solutions, polyving alcohol and the like and dried, so that the effective recycle of resources is achieved, and meanwhile the stability of promoters is also improved.

Description

technical field [0001] The invention mainly relates to the field of aerated bricks, in particular to a tailings aerated brick. Background technique [0002] Air-entrained concrete is a new type of wall building material. It is unique in that it is a very lightweight new type of building wall material for thermal insulation. The air-entrained concrete technology started a hundred years ago, and my country's technology started relatively late, 40 years behind foreign countries. However, the development of my country's air-entrained concrete industry is indeed very rapid. At present, the technical level of domestic aerated concrete has reached the international advanced level. In order to reduce the cost, the existing aerated bricks often result in a single variety, poor water resistance, moisture resistance, thermal insulation and other performances, and it is difficult to meet the development needs of the current society; [0003] At present, many biomass raw materials s...

Problems solved by technology

At present, the technical level of domestic aerated concrete has reached the international advanced level. In order to reduce the cost, the existing aerated bricks often result in a single variety, poor water resistance, moisture resistance, thermal insulation and other performances, and it is difficult to meet the development needs of the current society;

[0003] At present, many biomass raw materials such as bark and coconut shell are mostly used in fuel, feed and other fields, but there are still many remaining biomass raw materials, and these remaining raw materials also have problems such as processing difficulties, and aerated bricks are indispensable for social construction. Therefore, if the excessive surplus biomass raw materials are used for the production of aerated bricks, not only can the production cost be saved, but also the problem of excessive surplus resources can be solved, so as to make due contributions to the modernization construction
