  • Patent number: 7670415
    Abstract: Systems and methods for enhanced moisture vapor barrier performance for 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. Moisture vapor barrier properties are effected over an extended period of time as compared to control systems. The disclosed compositions and systems also yield reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces and, despite the water soluble properties of the compositions and systems, the treatments are effective in delivering an advantageous level of liquid moisture resistance to the treated concrete-containing structure and/or surface. The composition is synthesized from a feedstock that includes C9 to C16 branched hydrocarbons of varying structures.
    Type: Grant
    Filed: August 31, 2007
    Date of Patent: March 2, 2010
    Assignee: Hycrete, Inc.
    Inventors: David Rosenberg, David C. Darwin, John de Mars, Eugene B. Humphrey, Todd B. Humphrey, legal representative, Michael S. Rhodes, Philip S. Rhodes, legal representative, Philip S. Rhodes, James R. Humphrey, Leonid Izrailev, John Wojakowski, Jason Tuerack
  • Patent number: 7513948
    Abstract: Systems and methods for enhanced autogenous healing of cracks that are formed or are present in 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. Autogenous healing is effected at a greater rate and to a larger degree as compared to control systems. The disclosed compositions and systems also yield reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces and, despite the water soluble properties of the compositions and systems, 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 C9 to C16 branched hydrocarbons of varying structures.

  • Patent number: 7407535
    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 C9 to C16 branched hydrocarbons of varying structures.

  • Patent number: 7381252
    Abstract: An anti-corrosive additive composition is provided that includes an alkali-based salt of dioic acid and a defoamer agent. The defoamer agent is generally selected from the group consisting of a polyether modified polysilicane, a tri-alkane phosphate, a tri-alkene phosphate, and mixtures thereof. The anti-corrosive additive is particularly adapted for use with concrete compositions, e.g., a concrete composition that includes at least one rebar.
