Manufacturing Process



Raw Material Preparation

Autoclaved Aerated Concrete (AAC) is produced by mixing pulverized fly ash, cement, gypsum, lime, water, and a small quantity of aluminium powder, soluble oil, and plastic squeeze.



Batching Plant

Conecc’s fully automated batching plant enables accurate dosing, weighing and mixing of all the 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 into blocks with precision accuracy.




Autoclaving / Curing

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



Sorting / Packaging

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





Our product waste is placed back into the production process making it a totally recyclable product.
