Abstract

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.
