Abstract
Due to recurring environmental impacts, the current engineering works in search of solutions that minimize the environmental degradation, for example, using industrial residue to develop new materials. In the west region of Rio Grande do Norte, there is the accumulation of solid waste generated by quarrying In this way, seeking to minimize this environmental degradation, this work aims to propose the utilization of these industrial residues in a particulate polymer composite. For this, it was developed two materials using limestone, as mineral filler and polyester as matrix, the only difference between the materials is percentage limestone, being used the percentages of 10% and 30%. The limestone powder was used in the granulometry between # 100 and # 200 and was analyzed by X-ray fluorescence. To analyze the effect of the mineral filler on the material, the material constituted for 100% of polyester was made. The mechanical properties were analyzed by the uniaxial tensile test, based on the standard ASTM D638. It is noteworthy that by increasing the percentage of limestone powder, improves the rigidity and the decreasing in the tensile strength. Therefore, it is suggested that residue of limestone powder in quarries can be reused in the manufacture of new materials, reducing their quantity and avoiding damages to the environment, since it obtained advantageous results in the property of rigidity of the material.
