Patented technology and plants for manufacturing the BRETONTERASTONE® SLABS

The Bretonterastone® Slabs plants produce tiles and thin single layer slabs which are made by combining and compacting the materials using a “vibration vacuum process“. The stone mix consists of stone aggregates, fine mineral particles and inorganic based bonding agents.
Slab sizes measure up to a maximum 68x153 cm, with a finished thickness ranging from 15 to 35 mm.
Tile sizes available are 30x30 cm, 40x40 cm, 40 x 60 cm or 60 x 60 cm with a finished thickness, depending on size, from 9.5 up to 30 mm.
These slabs can be sold as they are or can be transformed into finished products.
The stone materials constitute up to 76% of the weight of the finished product and can be either siliceous (granite, quartz, quartzite, porphyry, sand etc.) or calcareous (marble, limestone, dolomite etc.) with sizes ranging up to 10-12 mm.
The bonding agent used is a Portland cement mix (“hydraulic” inorganic agent), generally Class I mixed with water to a water / cement ratio usually not higher than 0.30 and compounded with normal fluidifying agents used in the concrete industry.
With Bretonterastone® plants it is now possible to produce “P.M.C.” (“Polymer Modified Concrete”) products by simply adding to the concrete mix common polymers such as resins or polymeric latex (for example acrylic latex) enhancing the technical properties
and features of the finished product.
The production rate, depending on the plant model and layout, varies from 520 square metres up to 2,700 square meters per working day.
