Disposal of waste tires in nature is one of the significant environmental problems. Autoclaved Aerated Concrete is a lightweight or porous gaseous concrete. The use of crumbed rubber in autoclaved aerated concrete improves the mechanical properties of bricks and saves energy. On the other hand, because of the reduction in natural raw materials, concrete composite with rubber particles is both economically and environmentally friendly. In this study, autoclaved aerated concrete was produced in the presence of diffrent crumb tire particle size. The results showed that the presence of crumbed rubber changes density increases the plastic behavior of concrete and, increases the sound absorption ability. Reducing the size of rubber particles increases the sound absorption.
