<p>Process for manufacturing a concrete slab (1) and slab obtained in this way having a surface (2) formed by granules of natural stone embedded in a matrix of cement stone. In the process, concrete is prepared at least on the basis of soft granules of natural stone and cement, and this concrete being applied in a mould and enabled to harden in order to form a slab. The surface (2) of the hardened concrete slab (1) is treated by means of a milling cutter so as to cleave grains of said natural stone present therein and to obtain a rough surface (2) which is partially formed by the cleaved surfaces of the grains of natural stone. <IMAGE></p> |
