United States annually. The production of crushed stone aggregates generates, as a byproduct, quarry fines. Quarry fines are products that are produced as a result of the crushing operation, containing a large amount of fine material that passes the No. 200 sieve. Quarry fines may be dry screenings collected from below the last screen deck in
Jun 30, 2011· When landfills located near populated areas started refusing broken concrete in the 1970s, the construction industry started crushing it to make aggregate for use as compactible fill. Wood and steel reinforcement were separated out, leaving aggregate that often included a mixture of concrete, brick, and asphalt, along with some dirt.
