The BRETONCEMSTONE® plants produce large-sized slabs which are made by combining and compacting the materials using Breton patented “vibrocompression vacuum technology”. The stone mix consists of stone aggregates, fine mineral particles and “eco-hydraulic” bonding agent. Slabs sizes measure up to 14 0x308 cm, with finished thickness ranging from 9.5 mm to 30 mm.
Slabs can be sold as they are or can be transformed into finished products to the size required.The stone materials constitute up to 70% of the weight of the finished product and are in general either siliceous (quartz, quartzite, granite, porphyry, sand, etc.) or calcareous (marble, limestone, dolomite, etc.) with sizes ranging up to 6-8 mm.
Stone grits are bonded by an “eco-hydraulic” binding matrix consisting in a mix of inorganic hydraulic binding agents, including Portland cement class I, and a water-dispersed polymeric binder. The production rate, depending on the plant model, varies from 1.000 square metres up to 2.400 square metres per working day.
