The production of "autoclaved aerated concrete block" can make use of a large number of industrial wastes such as fly ash, tailings sand and desulfurized gypsum, which conforms to the strategy of developing circular economy and belongs to a new wall material encouraged by national policies.
Product characteristics
There is basically no difference between "ash aerated block" and "sand aerated block" in their functions, such as light weight, sound insulation, heat preservation, heat insulation and fire prevention. Moreover, in terms of product production, quality acceptance, performance testing, construction requirements, etc., the same national standard is adopted.
Place of use
From the perspective of use. Both of them are used as infilled walls of buildings, which can be used as internal and external walls and are the best self-insulation walls. Now it is customary to use "sand aerated block" on the upper external wall, and its frost resistance is slightly stronger than that of "ash aerated block".
♂? Construction method
Judging from the construction method. "Lime aerated block" mostly adopts "wet construction", that is, it is built with mixed mortar and painted after interface treatment; "Sand aerated block" mostly adopts "dry construction", that is, it is built with special adhesive, treated with special interface, and then leveled with surface batch. However, with the improvement of dimensional accuracy of "ash aerated block" products, the trend of "dry construction" appeared.
Product grade
"Autoclaved aerated concrete block" is divided into different grades according to product strength and bulk density (weight per cubic meter). Commonly used: strength A3.5, bulk density B06.
