Study of acustic absorption of concrete barriers with the addition of rubber and vermiculite residues

One way to mitigate noise dissipation is by installing acoustic barriers that act as obstacles between noise-generating sources and receivers. Acoustic barriers can be made with the addition of minerals, such as concrete, bricks, glass, aluminum panels, wood, acrylic sheets and metal.

After the gap is detected in the literature, it is proposed the study of an ideal concrete composition containing rubber residues and vermiculite that meet the required properties for acoustic barriers. At this stage of the project, a dosage study will be carried out to obtain a concrete trace containing rubber residues and vermiculite. Next, we intend to construct two concrete acoustic barrier prototypes, one of them produced with concrete containing rubber residues and vermiculite, and the other produced with traditional concrete.
