Abstract: A method is provided for upgrading rock in the form of aggregate, block, shaped stone or concrete structures involving the treatment of such rock with a dilute aqueous solution of polyelectrolyte and polyalkyleneglycol. Treated aggregate, portland cement and bituminous concrete compositions containing such treated aggregate are also provided.

Abstract: A method is provided for upgrading rock in the form of aggregate, block, shaped stone or concrete structures involving the treatment of such rock with a dilute aqueous solution of polyelectrolyte. Enhanced degradation resistance is achieved by further wetting the polyelectrolyte treated rock with a multi-valent ion metallic salt solution. Treated aggregate, portland cement and bituminous concrete compositions containing such treated aggregate are also provided.

Abstract: A method is provided for upgrading rock, for example building block, aggregate, preexisting stone structures, portland cement and bituminous concrete structures to render such rock more resistant to degradation resulting from environmental exposure. An organic condensation polymer containing rock treating composition in the form of a solution or dispersion is also provided based on the use of an organic condensation polymer, such as a silicone-arylpolycarbonate block polymer, an organic aliphatic polyamine and an organic solvent, as well as treated aggregate and improved cement and concrete compositions containing such treated aggregate.
