Dust and Fume Problems in the Cement Industry

The first Portland cement was shipped to the United States in 1868 and by 1895 had reached a peak import volume of 3,000,000 bbl. Americans began producing in-creasing amounts of Portland cement for themselves and by the turn of the century were manufacturing 500,000 bbl./yr. Today our production is approximately 250,000,000 bbl./yr.
