A concept for using recycled rubber granules in noise reduction concrete’s panels

Abstract

In traffic areas, from the outskirts of residences, systems for noise attenuation (induced by auto vehicles and trains) are necessary. Because these panels serve mostly the urban environment, they must have aesthetic aspects but at the same time must have to be easy to mount and to auto sustain themselves. Replacing the natural aggregates with recycled rubber granules results in rubberized plain concrete used mostly in non-structural constructions. Reuse of rubber from used tires can help prevent environmental pollution and, at the same time, contribute to building developments with lower costs. Concrete with recycled rubber has an energy absorption capacity proportionally increased. Deformation and energy absorption increase with the dimension of the rubber particle. This paper proposes the manufacturing of new protective panel systems made only from concrete with recycled rubber particles.
