Natural aggregates of the conterminous United States
William H. Langer
1988, Bulletin 1594
Crushed stone and sand and gravel are the two main sources of natural aggregates. These materials are commonly used construction materials and frequently can be interchanged with one another. They are widely used throughout the United States, with every State except two producing crushed stone. Together they amount to about...
