Abstract
For some time, one of the biggest concerns that the modern world is facing is to improve its relationship with the environment. Among these issues the improper destination of solid residue is highlighted, in the west region of Rio Grande do Norte, one of the most common environmental problems regarding solid residue, it is generated by quarries, where the industrialization of the crude stone produces the powder stone, which is not used in other processes and ends up accumulating in all surrounding area. In this scenario, this work aims to analyze the environmental effects generated by powder stone accumulation and develop a new material which makes use of those tailings. The purpose of this work is to develop two polymeric composites, using as reinforcement the mineral load (Granite, obtained by the quarry waste), in one the materials was used the percentage of 10% and in the other material was used the percentage of 30% of the stone powder. For both materials the polyester matrix was used. The mechanical characterization is performed by a uniaxial tensile test according to ASTM D638. To study the influence that the mineral load has on the polymer resin, purely polymeric specimens were also made. With the research it can be concluded that as the percentage of stone powder (Granite) increases, stiffness improves and tensile strength decreases, an increase of 55.75% and a decrease of 23.92%, of the 30% of the granite composite specimens in relation to the pure resin specimens, respectively.
