Acoustical properties of aerated autoclaved concrete ...

Mar 01, 2006  Introduction. Due to its physical properties aerated autoclaved concrete (AAC) may be used as a finishing material in construction works. However, the use of this material as an acoustic, sound absorbing material is not fully investigated yet. Previously, AAC products of high density (500–600 kg/m 3) have been analyzed.

This work analyses acoustic qualities of autoclaved aerated concrete (AAC). Three the most widely used types of AAC are chosen for the analysis: gas cement concrete, gas cement concrete with combined binder (Portland cement and lime), and foam cement concrete. The procedure and technique of the materials’ formation is presented in this work.

Sound insulation performance of aerated concrete walls

The positive acoustic properties of autoclaved aerated concrete as such can be attributed to its internal structure, however, its density is relatively low, which is why the sound insulation performance of AAC partitions can be worse than that of walls of the same thickness made of other materials (e.g. normal concrete, etc.).
