Terrazzo is a type of concrete manufactured with care and incorporating quality components: white cement, fine aggregates (powders and micro-aggregates) and chips, fragments or pieces of marble or other decorative materials. After adding water, this mixture is poured into a mould and then hardens naturally for several weeks. The next step is abrasive polishing, which removes a surface layer of 2-5 mm and uncovers the decorative aggregates. Finally, to harden the surface and brighten the colours a final fine surface polishing is done.
