Sand is the primary fine aggregate used to produce Portland Cement Concrete. It will not compact because of its particular shape. Produced only at specific plants, sand is sized into two specific classifications: Mason sand, used to produce masonary grout, and Concrete sand, which is used to make Ready Mixed Concrete. Other uses include golf course and recreational areas, beaches, walkways, and play areas.
Bituminus Concrete Sand is the main fine aggregate used in the production of Blacktop and is also used in residential sand mound construction. Other uses include walkways and play areas, trench lining, and any situations where an aggregate cushioning material is needed. The material will compact somewhat, but will not remain so.
Limestone Concrete Sand is used primarily in the mixture of concrete. This fine aggregate is sized and screened the same as Bituminus Concrete Sand, and it is also washed.
