Technical sheet of terrazzo

Composition and production. Terrazzo floors and objects are made of Portland cement, marble powder, inorganic cement pigments, sand and aggregates, cement additives and recycled marble and glass pieces. These components are mixed with water and moulded. The tiles dry and harden naturally during 3 to 5 weeks.
The last of factory production is a surface polishing, removing 2 to 5 mm to unveil the beauty of decorative aggregates.

Applicable standards. MOSAIC terrazzo tiles are not standardised and do not fall under any category of applicable norms. This is due to the production method as each tile is individually handcrafted. The laboratory tests have been carried out on 40x40x2cm Terrazzo Marble 10 tiles using various protocols and test methods for terrazzo or cement/concrete slabs. The results of these tests are applicable only to the tested tile.
