A Study on the Sound Absorption Coefficient and Void Characteristic of Foamed Concrete Using Bottom Ash

Sound absorption coefficient is affected by void in sound absorbing materials, therefore it is important to analyze properties of void pore. Also, it can be used to estimate performance of foamed concrete when it is applied to absorb sound. The purpose of this study is to analyze the sound absorption coefficient and void characteristic of foamed concrete using bottom ash. As a result of experiment, it was determined that an increase in sound absorption coefficient is achieved by increasing added amount of foam.
