Epoxy granite is one of these composite materials with an epoxy matrix and a reinforcement of different-grain-size granite particles. The epoxy granite samples were characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, surface area determination, viscosity analysis, density determination and compression and flexion tests. The results indicate that the epoxy granite samples with a composition of 30% matrix and 70% reinforcement show the highest values of elastic modulus (7,94 GPa compression, 2,78 GPa flexion), yield strength (73,96 MPa compression, 62,68 MPa flexion) and maximum stress (82,29 MPa compression, 68,09 MPa flexion). The results obtained become epoxy granite as a promising material for the referred application. Finally, it was proved that granite particles size lower than 149 µm are suitable as reinforcement material due to small value surface area, appropriate settling velocity and low quantity of cracks and pores in the grains. Los materiales compuestos han sido estudiados para su uso en la elaboración de fundaciones base de máquinas herramientas de precisión. Uno de estos materiales se denomina granito epoxi y consiste en un compuesto de una matriz epoxi y un elemento de refuerzo de polvo de granito. En el presente trabajo se explican distintas técnicas de fabricación de probetas de granito epoxi utilizando elementos de refuerzo con diferentes granulometrías, las cuales fueron caracterizadas por microscopía electrónica de barrido, espectroscopia dispersiva en energía de rayos X, difracción de rayos X, determinación del área superficial, análisis de viscosidad, determinación de la densidad, y ensayos de compresión y flexión. Los resultados indican que las muestras de granito epoxi con una composición ("30% matriz - 70% refuerzo" ) presentan los valores más altos de módulo elástico ("7,94 GPa compresión,2,78 GPa flexión" ), límite elástico ("73,96 MPa compresión,62,68 MPa flexión" ) y tensión máxima ("82,29 MPa compresión,68,09 MPa flexión" ), los cuales hacen a este material promisorio para la aplicación planteada. Finalmente, se demostró que las partículas de granito menores a "149 µm" son aptas para su utilización como refuerzo, debido a sus pequeños valores de área superficial y velocidad de decantación, y reducida presencia de grietas y poros.
