Remarks:
The above mentioned theoretical capacity does not include possible production waste, broken material, reduction in net volume, etc.
This capacity is calculated on the basis that above mentioned rising and autoclaving times can be met and is considered at a 100% mould utilisation. These times are very depending on the quality of the raw materials and other conditions which are under the responsibility of the Purchaser. These times might also extend in case of increased future reinforced element production.

Sand slurry35° C max.
Lime20° C max.
Cement20° C max.
Anhydrite20° C max.
Production water coldca. 15° C

2. Consumption values
According to our experience following consumption values may be used as indicative values. The specific raw material consumption will depend on the quality of the raw materials and the desired dry density and compressive strength of the finished product.For various dry density classes from 500 to 600 kg/m³ and average raw material quality, following typical consumption values may serve as a guideline for the production of 1 m3 AAC blocks:
Raw material vs. dry density500 kg/ m3600 kg/ m3
Sand292 kg352 kg
Lime62 kg98 kg
Cement99 kg99 kg
Anhydrite18 kg21 kg
Water (total, excl. steam)382 kg442 kg
Aluminium (metal powder)0,46 kg0,39 kg
Total solids471 kg570 kg
For the production of AAC panels additives (e.g. MgO) are needed to adjust the shrinkage of the AAC relative to the steel reinforcement . Further it is not advisable to produce AAC panels using flyash.
average consumption
per m³ of AAC
Electrical power consumptionca. 18- 21 kWh
Steam consumption (water)ca. 180 kg
Natural gas consumption
(dependant on boiler and foiling)		ca. 11 - 14 m³
