Nov 11, 2019· If we are doing a drain system, we want larger rocks with no stone dust. We would call the quarry and order "4" washed clean stone." Or, if we were putting the base down for a patio, we want stone that compacts well and makes a strong base. Therefore, we want our stone to have stone dust, so we would call the quarry and order "2 ...
Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
