Abstract
A method and formulation are shown for capping the exposed surface of an aggregate of materials, such as exposed land areas with fine particulate mining wastes. A mineral formulation is prepared by mixing together lime, a pozzolanic component, a sulfate component, a cellulosic component and water. The mineral formulation is applied to the exposed aggregate and is allowed to harden to form a surface coating thereon. A seed component or a coloring additive can be incorporated within the slurry for revegetating land areas and to enhance the esthetic appearance of the hardened cap.
