Quarry Waste
Quarry fines are the inherent fraction of an aggregate below 63 μm, as defined by BS EN 1377:2. However more commonly quarry fines are defined as the sub-mm 'sand' fraction that is the undersize from screening coarse aggregate and the 63 μm fraction, as the airborne dust, collected by extraction filters [66]. Only waste and fines from ...

As 20% of the total material stream turns into fines at the quarry, we expect fines for andesite and dacite to be readily available for purchase (Renforth, 2012). While these fines may be perfectly suitable for EW, their safe and effective collection and use for land application and ultimate weathering rates is an uncertainty in the supply chain.

Quarry fines, defined by the BS EN aggregate standards, are the inherent fraction of an aggregate passing 0.063 mm (63 microns). Many quarries also refer to their (sub-economic) fine aggregate (finer than 4 mm) as 'quarry fines' or 'quarry dust'. The term is used here to denote both fine aggregate and quarry fines.
