The basis for continuous high quality

Aerated concrete is produced from quartz sand, lime, cement, gypsum (anhydrous), and water.

The process starts with quartz sand being milled in a wet ball mill into a fine sand slurry which is then stored in slurry silos with an integrated stirrer.

It is important to keep the defned density, which is controlled either manually or automatically. Sand slurry, recycled slurry, lime, cement, gypsum, aluminum and water are added to the mixer according to the desired product recipe.

Immediately after the mixing the pre-positioned moulds are filled and subsequently transported to the fermentation area. Here the mixture starts reacting by producing fine pores, allowing the mass to harden into an aerated concrete cake.
