ACOUSTIC PROPERTIES OF AERATED CONCRETE

Abstract - This paper discusses acoustic properties of aerated concrete aerated by colloidal gas aphrons.. The dependence of acoustic resistance on density of light weight material has been discussed. Two different sound levels at source have been used to study the change in sound resistance with density, and surface density. Sound absorption coefficients have been also studied with respect to ...

Acoustical properties of aerated autoclaved concrete ...

01/03/2006  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. Sound absorption coefficient of such products is low unless they are specially

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. The evaluation of acoustic qualities of AAC is ...

The sound absorption of acoustic insulation concrete (AIC) can be improved by forming open pores in concrete matrices by either using a porous aggregate or foam agent. To this end, this article reviews the noise and sound transmission in buildings, types of acoustic insulating materials, and the AIC properties. This literature study also provides a critical review on the type of concretes, the ...

Acoustic Properties of Precast Concrete

Acoustic Properties of Precast Concrete In today’s cities people are living closer and closer together primarily due to urban consolidation. The need to utilise services and infrastructure, to be close to work, and to be close to entertainment is of high priority. Medium density living in modern architect-designed glass and concrete structures is very much in demand, and thus it becomes the ...

Aerated concrete is relatively homogeneous when compared to normal concrete, as it does not contain coarse aggregate phase, yet shows vast variation in its properties. The properties of aerated concrete depend on its microstructure (void-paste system) and composition, which are influenced by the type of binder used, methods of pore-formation and curing. Although aerated concrete was initially ...

Aerated concrete is one of the light weight concrete. It is a mixture of water, cement and finely crushed sand. Aerated concrete is obtained by introducing gas bubbles into the plastic mix of cement and sand mortar. The product obtained is cellular in structure containing voids of size 0.1 to 1 mm similar to sponge rubber. The skin of cells or voids must be able to withstand mixing and ...

HUMIDITY INTRUSION EFFECTS ON THE PROPERTIES OF SOUND ...

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.) [3]. Sound insulation requirements for internal and external walls ...
