“Ventaglio/Curva” paving slabs are widely used for porticoes, courtyards, pavements, driveways, car-parks, terraces and other similar places.
VENTAGLIO/CURVA - COMPOSITION ANALYSIS
“Ventaglio/Curva” tiles are made with a vibro-compressed agglomerate of high-strength cement (PTL 425), marble powder and grains obtained from the grinding of accurately selected hard stones and porphyrys imparting a compactness and hardness to the product equivalent to that of a natural stone.
Each flag is about 3.8 cm thick, the top layer (1.5 cm) consisting of the above materials, the base layer (2.3 cm) of silica sand and high-strength cement (PTL 425) at a ratio of 400 kg x 1 m3 sand.
