The presente work analyzes the influence exerted by the addition of recycled rubber from tires in the concrete execution, whose activity significantly contributes to the reduction of this type of waste in the environment, thus presenting its social character, in addition to the search for the improvement of the properties to the concrete. The uncontrolled urban growth brings a certain concern to the sustainability question, a fator that helps in the emergence of many possible constructive methods on the civil construction use, because the Market ends up requiring improvements. It is interesting to expand this bias in something that contemplates the use of concrete with certain type os residue, on the case of tire (synthetic rubber), providing a rational and efficient disposal to the same. In order to understand the need for sustainability nowadays, a study was carried out for future tests of compressive strenght and diametrical compression traction, with a certain rubber content, differing additions of the residue in question (5% and 10%), being able to be compared with the values of conventional concrete, in this case, without addition of rubber. In order to substantiate the performance of the concrete with the addition of tire rubber, the concrete with 5% and 10% of rubber presented a compressive strenght of 30 MPa and 15 MPa, respectively, showing that the percentage of 5% be used in structural works and 10% in non-structural works. The diametrical compression tensile strengths, however, presented reduced values in relation to the base concrete. Analyzing the rupture of the test specimens, significant alterations are observed demonstrating the effective physical participation of the residues in them. In this way, it isn’t possible to use tire rubber in civil construction.
