Abstract
Due to recurring environmental impacts, the current engineer works for solutions that minimize environmental degradation. For example, using waste to develop new materials. In the western region of Rio Grande do Norte, stands the solid waste generated by the quarries (stone powder), which cause several problems in the environment. Therefore, in order to minimize environmental degradation, this work aims to propose the use of these wastes as cargo in a particulate polymer composite. For this, four materials were developed using these tailings (limestone powder and granite powder) in different proportions (10% and 30% by mass) as filler and the polyester resin as matrix. The mechanical properties were evaluated using the uniaxial tensile test, based on ASTM D638. By means of the results obtained, it was possible to notice that the granite material had better stiffness and limestone had better strength, when compared 10% and 30% of stones, respectively. Therefore, it is suggested that these waste tailings in quarries can be reused in the manufacture of new materials, reducing their quantity and avoiding damages to the environment.
