Acoustical properties of aerated autoclaved concrete ...

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.

Structure and properties of aerated concrete: a review ...

2000-10-1  Aerated concrete can be non-autoclaved (NAAC) or autoclaved (AAC) based on the method of curing. The compressive strength, drying shrinkage, absorption properties etc. directly depend on the method and duration of curing. The strength development is rather slow for moist-cured products.

HUMIDITY INTRUSION EFFECTS ON THE PROPERTIES OF

2019-4-21  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.).

Aerated Concrete - an overview ScienceDirect Topics

In general, autoclaved aerated concrete (AAC) is an ultra lightweight concrete with a distinct cellular structure. It is approximately one-fifth the weight of normal concrete with a dry bulk density ranging from 400-800 kg/m 3 (25-50 pcf) and a compressive strength ranging from 2 to 7 MPa (300-1000 psi) (
