Abstract

The invention provides an ALC wallboard containing construction waste and a preparation method thereof, and relates to the technical field of pre-loaded concrete walls. The ALC wallboard containing construction waste is mainly prepared from raw materials such as cement, construction waste aggregate, gypsum, phenolic resin, a crack-resistant waterproofing agent, soluble oil, an aluminum powder suspension, water, etc. according to the ALC wallboard containing construction waste that is prepared from the above raw materials at a certain ratio, the desiccated bulk density is 870-910 kg / m<3>, and compressive strength is greater than or equal to 6.1 MPa. Meanwhile, the ALC wallboard also has good frost resistance. In addition, by replacing part of fly ash, cement and concrete and other raw materials with the construction waste for the preparation of the ALC wallboard, the method has advantages of low cost, high utilization rate of construction waste and the like, and is also of great environmental protection significance. Comprehensive utilization of abandoned construction waste is realized, the ecological environment is cleaned, and especially the environmental problem caused by massiveaccumulation of construction waste is solved.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete walls, in particular to an ALC wallboard containing construction waste and a preparation method thereof. Background technique [0002] With the continuous deepening of the reform of wall materials in our country, clay, as a non-renewable resource, has been paid more and more attention by people. In order to protect clay resources, the production and use of wall materials using clay as raw materials has been gradually banned in 160 large and medium-sized cities across the country. Therefore, a large number of new wall materials have emerged in recent years, and ALC board is one of them. [0003] ALC is the abbreviation of Autoclaved Lightweight Concrete, which is a kind of high-performance autoclaved aerated concrete (ALC). ALC autoclaved lightweight concrete is a kind of porous concrete forming board cured by high pressure steam. ALC board can be used not only as wall material, b...
