limestone was 68% of all crushed rock produced in the United States. Also, limestone is the key ingredient in making Portland cement. Despite our Nation's abundance of limestone, there have been cement shortages in recent years. Some of the purest of natural lime-stones are marbles. For centuries, marble has been the decorative stone of choice in
Crushed gravel is frequently used to fill driveways and drainage areas. Many times, the small, smooth stones and rocks on or around the bottoms of creeks and rivers are collected to be used in building and landscaping. Over time, the moving water washes the stones along the bottom, chipping away any jagged edges and smoothing the stone.
most of the remainder are crushed stones. Naturally occurring concrete aggregates are a mixture of rocks and minerals (see Table 5-1). A mineral is a natu-rally occurring solid substance with an orderly internal structure and a chemical composition that ranges within narrow limits. Rocks, which are classified as igneous, sedi-
