RAW MATERIALS
The raw materials utilised for manufacturing BRETONSTONE® slabs are Aggregates, Mineral Fillers, Bonding Agents, Additives and Colouring Agents.
AGGREGATES
Are stone materials mixed with the bonding agent to create the stone mix to compact.
Aggregates can be siliceous such as quartz, granite, porphyry, basalt, quartzite, silica sand or calcareous as marble, dolomite, coloured stones etc. The aggregates used can be either in sand or grain form and / or various size stones. The nature, size and grain size scale of the aggregates are chosen depending on the appearance and physical- mechanical properties of the final product to produce.
Aggregates can be purchased direct from the producer already dried and divided into the various grain sizes required, or as an alternative solution it is possible to install, adjacent to the BRETONSTONE® plant, a stone crusher and screening machine.
