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.
Quarry blocks are subdivided by breaking them into smaller blocks that can be removed from the quarry and sent to the mill. Typical mill blocks range in size from 12 to 30 t, but they can reach weights as large as 65 t. Quarry operations thus involve cutting the stone, breaking the stone, and removing the stone from the quarry.

The stone quarries of ancient Egypt once produced quality stone for the construction of decorative monuments such as sculptures and obelisks.These quarries are now recognised archaeological sites. Eighty percent of the ancient quarry sites are in the Nile valley; some of them have disappeared under the waters of Lake Nasser and some others were lost due to modern mining activity.
In fact, actual pit excavations at ancient quarries are uncommon at best, documented at fewer than 10 percent of known sites. Far more typical was casual surface collection of nodules in gravel deposits and of blocks broken away from bedrock outcrops by natural forces.
