Corrosion resistant composition for treatment of concrete structures

Abstract

Water soluble materials, compositions and systems for use in treating concrete-containing materials and surfaces are disclosed. Treatment modalities that include addition of the disclosed materials, compositions and systems to pre- and post-construction concrete-containing materials and surfaces are provided. Reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces. In addition, despite the water soluble properties of the material, composition or system, the treatments are effective in delivering an advantageous level of moisture resistance to the treated concrete-containing structure and/or surface. The composition is synthesized from a feedstock that includes C 9 to C 16 branched hydrocarbons of varying structures.

       12. A method according to  claim 9 , wherein the concrete-containing structure or surface substrate is a post-construction structure or material; and
 wherein the composition is combined with the post-construction structure or material by applying the composition directly to a surface of the post-construction structure or material after the post-construction structure or material has hardened. 
 
     
     
       13. A method according to  claim 12 , further comprising the step of adding a thinning agent in an amount of about 5% to about 70% by weight to the composition prior to application of the composition to said surface.
