Abstract
A method and formulation are shown for capping dust-emitting bulk materials, such as materials being conveyed in open rail cars. A mineral formulation is prepared by mixing together lime, a pozzolanic component, a sulfate component, a fibrous component and water. The mineral formulation is applied to the surface of the dust-emitting bulk material and is allowed to harden to form a surface coating thereon.
