- the ground raw materials sand, lime, cement, sulfate carrier and aluminum powder are metered in batches together with water in a mixer. After mixing, the material is poured into an oiled mold with a volume between 4 and 9 m 3 . After the casting mold has been filled, it is brought to a fermentation place, where the mass is fermented to its final volume and remains between one and six hours until the binding component has set enough green strength for the sawing. When the green strength is sufficient, the material is removed and then cut using wires in a sawing station.
- the material After sawing, the material is either collected at further locations in front of the autoclave until there is an autoclave filling or it is fed directly into the autoclave. After autoclaving, the usual autoclaving time is approx. 12 hours, the material is removed from the autoclave, unloaded in a discharge device, packaged and transported to the warehouse.
- the cleaned and oiled Molds filled with an aerated concrete mixture and then on Proofing stations 102 move where the mass floats in the molds and sets.
- the green ones become in a demolding station 103 AAC cake tilted by 90 ° and part of the mold removed, while a mold side wall is used as a hard floor remains.
- Another possibility is the implementation of the cellular concrete cake on grids so that the entire shape is removed becomes.
