<p>A sheet of conglomerate material is formed with a visible surface having the form of so-called split stone or crocodile skin using a multiple mix consisting of at least two single mixes each formed by a granulated stone material and a hardening binder. At least one of the single mixes comprises a granular material having a hardness less than that of the granular material of the at least one other mix. When the sheet, vacuum vibrocompressed and hardened, is machined using a non- rigid abrasive tool, the surface zones (14) where the mix with the granular material of lesser hardness is present are scored to a greater degree, producing the aforementioned aesthetic effect. If, on the other hand, granules (26) of a material with a very high hardness are added to the mix, a sheet with non-slip properties is obtained.</p> |
