For 2018, the Rock Products Market Composite is 2.616 billion tons of material produced. That is compared to 2.448 billion tons of material pro- duced in 2017, an approximate 6% increase. Here is market data by commodity segment: Crushed Stone – In 2018, 1.41 billion tons of crushed stone valued at more than $16.6 billion was produced by an estimated 1,465 companies operat- ing 3,710 quarries and 176 sales and (or) distribution yards in 50 states, an increase of 4% compared with 2017. Leading states were, in descending order of production, Texas, Pennsylvania, Florida, North Carolina, Ohio, Missouri, Georgia, Virginia, Tennessee and Illi- nois, which together accounted for more than one-half of the total crushed stone output. Of the total domestic crushed stone produced in 2018, about 68% was lime- stone and dolomite; 15%, granite; 6%, traprock; 5%, miscellaneous stone; 4%, sandstone and quartzite; and the remain- ing 2% was divided, in descending order of tonnage, among marble, volcanic cinder and scoria, calcareous marl, slate, and shell. It is estimated that of the 1.5 billion tons of crushed stone consumed in the United States in 2018, 75% was used as construction material, mostly for road construction and maintenance; 13% for cement manufacturing; 7% for lime manufacturing; 3% for other chemical, special, and miscellaneous uses and products; and 2% for agricultural uses. Construction Sand and Gravel – Con- struction sand and gravel production was about 961 million tons in 2018, an increase of 7% compared with that of 2017. Demand for construction sand and gravel increased in 2018 because of growth in the private and public con- struction markets, especially after this segment being flat during the past two years. Commercial and heavy-industrial construction activity, infrastructure funding, new single-family housing unit starts, and weather affect growth in sand and gravel production and consumption. Long-term increases in construction aggregates demand will be influenced by activity in the public and private construc- tion sectors, as well as by construction work related to security measures being implemented around the nation. The underlying factors that would support a rise in prices of construction sand and gravel are expected to be present in 2019, especially in and near metropolitan areas Industrial Sand and Gravel – In 2018, industrial sand and gravel production WE HAVE THE CRUSHER PROTECTION SOLUTIONS YOU NEED 800-835-2526 / ©2019 Bunting Magnetics Co.
