Abstract:
The industrial sector in general generates a considerable amount of waste, with a special focus on granite, it has been generating considerable volumes of waste, resulting in negative environmental impacts caused by inadequate disposal. With this fact in focus, the opportunity arises to value this waste through the production of artificial rocks, combining sustainability with favorable technical and economic performance. The present study aims at the production and characterization of artificial granite using a polymer matrix of epoxy resin with the implementation of a synthetic fiber in which glass mesh fiber was used, where the rock is produced using the vacuum vibro compression method. The granite cutting residues were fragmented and, using the Simplex Centroid Model, the ideal granulometric mixture for compaction was determined. The minimum amount of resin required to fill the spaces between the particles was calculated. The artificial rock slabs were produced with 85% by mass of granite particles using a grain size that was considered coarse and 15% polyester resin (RAPO). Under a vacuum of 600 mmHg, the plates were subjected to compaction pressure of 10 tons, at 90°C for RAPO and 80°C for the others, for 20 minutes. After sanding and cutting, the plates were evaluated for their physical characteristics (density, apparent porosity, water absorption), mechanical (3-point bending test, wear), resistance to chemical attacks and staining, and microstructure by Electron Microscopy. Scan. The results obtained demonstrate that artificial rock has suitable properties for application in coatings.
