Abstract
A cover composition comprises at least about 50 weight percent water, about 1 to about 50 weight percent of cement and/or fly ash, at least some fiber, at least some water dispersible polymer, and at least some acid, the cover composition being free of foaming agent. The acid is present in an amount sufficient to maintain the pH of the bulk material cover composition between about 1.0 and about 6.0. Also provided is a composition consisting essentially of about 70 to about 80 weight percent cellulosic water dispersible polymer, about 15 to about 30 weight percent fiber, and about 0.1 to about 5 weight percent acid, wherein the acid maintains the pH of the composition between about 1.0 and about 6.0.
