Autoclaved aerated concrete production plants

Our AAC plant ensures outstanding levels of productivity and flexibility: zero system waste, highest-precision cutting, low energy requirements (optimum kWh/m3 values) and minimal consumption of raw materials.

We supply complete plants or individual machines, depending entirely on specific requirements of our clients. We take account of all the relevant factors and conditions, such as production quantities, location, space available, level of investment and much more. We offer the capacities from 50,000 up to 300,000 m3 per year AAC blocks to ideally serve the individual requirements of our customers. And the plant will be custom-made to your specific requirements.

Every individual part of a production line is a link in a long chain of actions and reactions. The key is perfect flow.

Production process of autoclaved bricks

Autoclaved aerated concrete (AAC) is produced by mixing the raw materials sand or fly ash, cement, gypsum, lime, water and a small quantity of aluminium powder.

Our fully automatic dosing and mixing plant enables accurate dosing, weighing and mixing of all raw materials. The mixture is then poured into moulds, where chemical reactions cause it to rise like a cake.

After the cake has attained sufficient strength, it is removed from the mould and cut with wires and knives into blocks or panels with precision accuracy. Hand holds, tongue and groove are cut before the cake is autoclaved in order to avoid milling into the hardened material a sustainable cost-saving measure and an element of our “zero system waste” concept.

After cutting, the AAC is hardened by autoclaving in a saturated steam atmosphere at a temperature of approx. 180 – 190°C. It is this steam curing that creates the unique crystalline structure and lends AAC its excellent qualities in comparison to building materials which are not steam cured.

After autoclaving the blocks or panels are packed and are then ready for dispatch to the construction site.

The complete process is split up into stages that are controlled fully automatically. Personnel is only required for monitoring purposes.
