Patent ID: 8883868

Claim:
A composition consisting essentially of rock dust, water, a pumping aid, and a polymer; wherein the composition has a water content and a polymer content sufficient to allow the polymer (i) to disperse water molecules within the composition and, upon drying of the composition, (ii) to dissipate forming void spaces in the dried composition; wherein the dried composition comprises agglomerated particles, said agglomerated particles comprising polymer chains having rock dust particles attached thereto; wherein the water content is from about 15 to about 40 percent by weight of the composition, and the polymer content is from about 0.001 to about 0.1 percent by weight of the composition; and wherein the pumping aid consists essentially of a surfactant or a gas incorporated into the composition; wherein the surfactant is present in an amount sufficient to make the composition pumpable and to disperse the polymer.
