Inert material from quarry

The inert material aggregates obtained by rock grinding, from quarry activities. It is characterized by a selected granulometry to 0/4 mm until 0/80 mm.(25/40, 0/200, 0/12, 0/15, 0/40, 40/70, 80/100, 0/4, 0/6, 4/8, 6/12, 12/20, 100/150). It can be used in building sectors, depending on the characteristics and chemical composition of the stone of origin. It is mainly used as calcium carbonate additive in agriculture (e.g. fertilizer or chemical for organic management). 

In this document, limestone, calcium carbonate and CaCO3 will be used as synonymous.
