Aggregates for Concrete - University of Memphis

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.

Crushed Edwards Limestone Base | Texas Crushed Stone Co.

Crushed Edward's Limestone Base was inexpensive, easily placed, and resulted in long lasting, smooth riding roads. The only equipment required to place crushed stone base is a motor grader, water truck and compaction roller. By the mid 1950's, this crushed base material was the standard road building base material in the Austin area.

neutrons. Moisture is determined by the relationship of nuclear count to mass of water per unit volume of soil. The more water that is present, the more hydrogen atoms that will be slowed down and reflected back to the detector tubes to be counted. The moisture content is used in conjunction with the density measurement to determine dry density.
