Abstract:
The Brazilian ornamental stone sector has been growing and bringing new technologies for better use of stone materials intended for cladding in civil construction. However, there is a great environmental liability in this sector, due to the residues that are generated in different stages of the production process, which, in general, are sent to sanitary landfills. The use of waste for the manufacture of artificial stone ais one of the alternatives for the production of a technically viable material, aiming at the loss of waste and of great economic value. Over the last few years, Brazil and the world have been significantly increasing the production of artificial stones, being applied mainly in the finishing of civil construction, due to the quality of the final product and also its application versatility. This work aims to produce and technologically characterize an artificial stone with magmatic stone residue commercially known as Branco Fortaleza. Residual stones from the monitoring process of the slab block were used in the multiwire diamond loom equipment. The residues were used in three granulometric ranges (coarse, medium and fine) according to ABNT NBR 16.483/2020, where a granulometric composition of greater particle packing was determined. Regarding the epoxy matrix, plates with 12% resin were produced. For the production of artificial stone plates, the residues were mixed with the resin, and then a hydraulic press was used by vibration at a temperature of 90°C. The results of the technological properties of artificial stones showed good results and far superior to those adopted by the Brazilian technical standards ABNT NBR 15844/2015, and can be safely applied in civil construction.
