effect of rubber powder on autoclaved aerated concrete properties

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#
