Autoclaved aerated concrete (AAC)
The aim here is to significantly increase the stability of AAC without compromising its heat-insulating properties. By adding a variety of solid admixtures to the initial low-viscosity suspension, it should be possible to substantially increase the load-bearing capacity of the resulting AAC products. This has led to the construction of a porous concrete laboratory facility. It has been designed to enable testing on a wide range of parameters and to ensure that laboratory scale practice can be directly transferred to production.
Porous materials absorb noise and can positively influence indoor conditions so that people’s health, well-being and performance are stimulated. They are very cost-effective materials, providing both good acoustic dampening properties and sufficient stability, while at the same time being easy to produce. Testing revolves around how the autoclaving / compacting process, particle size distribution and the amount of binding agent affect the properties of this heat-insulating / sound absorbing building material.
