Description

1. Technical field

[0001] The invention relates to a preparation technology of a high-strength load-bearing autoclaved aerated concrete wall material, in particular to a method for preparing load-bearing autoclaved aerated concrete by using chemical white mud slag. 2. Background technology

[0002] The national wall material innovation plan and the 2010 development plan clearly pointed out: "my country's cross-century wall materials should focus on the development of light-weight, high-strength and energy-saving new wall materials." The Ministry of Construction's Building Energy Conservation Plan and the 2010 Plan put forward higher energy-saving standards for building heating and air conditioning energy consumption: "The first stage is the general reduction of 30% in new heating residential buildings before 1996; 30% energy saving on the basis of the second stage is the second stage; on the basis of reaching the second stage from 2005, another 30% energy saving is the third...
