Abstract

The present invention discloses a lightweight high-strength press molding block and a production method thereof. The block is prepared through carrying out treatments of material preparing, mixing and stirring, pressing formation and autoclave curing for a digested mixed material and a lightweight coarse aggregate, wherein the pile volume content range of the digested mixed material is 50-60%, the pile volume content range of the lightweight coarse aggregate is 40-50%. The digested mixed material is prepared from a fine aggregate material and a cementing material, wherein the fine aggregate material is a mixture comprising one or more than two selected from fly ash, slag, coal slag, coal gangue, shale, and has a particle size less than 3 mm, the cementing material is a mixture comprising one or more than two selected from quick lime, cement and carbide slag. The produced block provided by the present invention has characteristics of small density, high strength, good insulation property, simple production method, waste utilization and environmental protection, and provides significant social and economic benefits.

Description

technical field [0001] The invention relates to a building material and a production method thereof, in particular to a light-weight high-strength compression molded block with industrial solid waste as the main raw material and a production method thereof. Background technique [0002] my country is a big developing country, and it is also a big building country. The area of ​​newly built houses reaches 1.7-1.8 billion square meters every year, which requires a lot of building materials. At the same time, with the vigorous promotion of national energy conservation and emission reduction, wall material innovation and the needs of sustainable development, research and development of new lightweight high-strength wall materials has become an inevitable trend in the development of building materials. The main raw material of lightweight high-strength block products is industrial solid waste. The product has the characteristics of light weight and high strength, good thermal ins...
