The invention relates to a method of producing artificial stone slabs that are particularly suitable for external use. The inventive method comprises the following steps consisting in: grinding the different materials with varied grain size that form the filler; storing the resin with the catalyst and, optionally, the colouring agent; mixing the aforementioned constituents until the materials have been homogenised with the resin; moulding and compacting the paste obtained by means of vibro-compression under vacuum; heating the resin in order to harden same by means of polymerisation; and cooling and polishing same.
L'invention concerne un procédé de fabrication de panneaux en pierre artificielle convenant particulièrement à l'extérieur et comprenant les phases de: trituration des différents matériaux de granulométrie variable formant la charge, confinement de la résine avec le catalyseur et facultativement le colorant, mélange des matériaux précités jusqu'à homogénéisation des matériaux avec la résine, une phase de moulage et de compactage de la pâte obtenue par vibrocompression sous vide et une phase de durcissement par polymérisation de la résine par un chauffage, s'achevant par une phase de refroidissement et de polissage.
