Abstract
Autoclaved Aerated Concrete (AAC) has been well known in Central Europe for decades. In traditional cement and concrete research a huge increase of knowledge has improved the material behaviour and efficiency. The understanding of the mineral reactions and properties in AAC has also improved, but several relations are still unknown. While the influence of ordinary raw materials (quartz, fly ash, free lime, cement, gypsum, Al-powder, water) is mostly known, the behaviour of non-traditional substitutes for environmental purposes can so far only be determined by trial and error. In this research a closer look is taken on the influence of granite on AAC, before and after autoclaving. The aim is to understand the reactions with the aim of improving the characteristics of AAC.
The parameters for the fresh material properties are for example the slump flow, rising height over time, temperature development and green-body strength, while in the final AAC the compressive strength, the raw- and true density, the thermal conductivity, the phase content and the microstructure are determined.
