主权项

1. A method of providing a cover to a bulk material pile, the method comprising:
providing a bulk material cover composition free of foaming agent comprising:
at least about 50 weight percent water,about 1 to about 50 weight percent of at least one of cement and fly ash,at least some fiber,at least some cellulosic water dispersible polymer, andat least some acid; applying the composition onto the bulk material pile; and allowing the composition to harden to provide a cover to at least a portion of the bulk material pile, wherein the acid is present in an amount sufficient to maintain the pH of the cover composition between about 1.0 and about 6.0.
