Crushed limestone is an aggregate composed of calcium carbonate. Once mined, the stone is crushed to specific sizes where it can be used in a variety of applications such as building materials, drainage, concrete, backfill, and road bases. If you've dealt with limestone in the past, you've likely noticed that there are different grades (sizes).
