Abstract
A method for transporting a cementitious mixture to an underground space includes subjecting the mixture to high-shear mixing to render it temporarily flowable and, while the mixture remains in its flowable state, transporting the mixture to the underground space. After a period of time following the high-shear mixing, the mixture reverts to its initial viscosity and subsequently reacts to form a cementitiously hardened product. The mixture used in the present invention includes flue gas desulfurization sludge, lime, fly ash and water.
