Product Glossary
Construction aggregate or simply "aggregate", is coarse particulate material, including sand, gravel, crushed stone and recycled concrete. Aggregates add strength to composite materials such as concrete or asphalt. Aggregates are also used extensively in drainage applications and as base material under foundations, highways, railroads and dams.
Northern Aggregates, Inc. (NAI) has an excellent aggregate supply, principally from Harris Quarry. Precision crushing, screening and washing machinery produces strong aggregates that can meet rigorous state and federal project specifications.
