Why do all the information on the Internet sell non-steaming aerated block equipment? Has anyone invested in the production of the equipment in use? Is the technology mature? Does the builder accept it? I wonder if anyone has put it into production. What I know is that only those who sell equipment say no steaming. The purpose is to buy you equipment. This technology is out of date.

Article 3. 1.4 of the national standard GB 50574-20 10 "Technical Specification for Application System of Wall Materials" clearly stipulates that "non-autoclaved silicate bricks (blocks) shall not be used in walls" and also clearly stipulates that "non-autoclaved aerated concrete products shall not be used in walls".

In the "Guidance Catalogue for Eliminating Backward Production Process Equipment and Products in Some Industrial Industries (20 10 Edition)", IV. Building materials, Article 33 points out that "non-autoclaved aerated concrete production line, hand-cut aerated concrete production line" means eliminating backward production process equipment and products.

Category III 20 19 of Catalogue of Industrial Structure Adjustment: Elimination Category (VIII) Building materials 24 lists "manual cutting of aerated concrete production line and autoclaved curing-free aerated concrete production" as elimination category.

Due to the lack of necessary curing technology, the durability of autoclaved aerated concrete products is poor, which will bring hidden dangers to wall application. Therefore, we should be cautious about such products.
