Light refractory brick and production method thereof

Abstract

The invention discloses a light refractory brick and a production method thereof. The light refractory brick is characterized by comprising the following raw materials in parts by weight: 60-90 parts of fly ash, 5-10 parts of perlite, 2-4 parts of sawdust, 5-10 parts of silica, 5-10 parts of floating beads, and 4-6 parts of a binder. Compared with the prior art, the light refractory brick has the advantages of being environmentally friendly, and fully utilizing the fly ash for developing a brick body, thus not only providing a new way for comprehensive utilization of the fly ash, but also being a compensation for increasingly rare raw materials for producing bricks, with great economic and social benefits. The product disclosed by the invention has uniform and beautiful appearance and color, neat edges and corners, and uniform cross-section tissue, without a phenomenon of cracks or collapsing, and exceeds the national standard of clay light bricks in terms of heat conductivity coefficient and strength.

Description

technical field [0001] The invention relates to the technical field of environmental protection bricks, in particular to a lightweight refractory brick and a production method thereof. Background technique [0002] At present, fly ash is one of the industrial wastes with a large discharge volume in my country, and the annual discharge volume of China's slag has reached 30 million tons at this stage. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere. If it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms. Therefore, the processing and utilization of fly ash has attracted widespread attention. Advantages of using fly ash Adding fly ash in concrete saves a lot of cement and fine aggregate; increases the decorativeness ...
