The composition may further include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition for application directly to the surface of the post-construction material. The composition is effective for reducing corrosion of post-construction materials, including unreinforced concrete or reinforced concrete, and reduces the permeation of moisture and/or the extension of cracks/fissures within the post-construction material. The composition may be applied to the post-construction material through brush applications, spray applications, mist applications or the like.Type: GrantFiled: October 28, 2005Date of Patent: August 28, 2007Assignee: Hycrete, Inc.Inventors: Philip S. Rhodes, David Rosenberg, John Wojakowski

Patent number: 7172022Abstract: The present invention provides cement compositions that include degradable materials, and methods of using such compositions in subterranean cementing operations. An example of a method of the present invention includes: providing a cement composition that includes a hydraulic cement, and a degradable material; placing the cement composition in a subterranean formation; allowing the cement composition to set therein; and allowing the degradable material to degrade. Another example of a method of the present invention is a method of enhancing the mechanical properties of a cement composition including adding a degradable material to the cement composition and allowing the degradable material to degrade.Type: GrantFiled: March 17, 2004Date of Patent: February 6, 2007Assignee: Halliburton Energy Services, Inc.Inventors: B. Raghava Reddy, Frank Zamora, Philip D. Nguyen, Trinidad Munoz, Jr., Anthony V. Palmer

Patent number: 7147706Abstract: Cementitious compositions having high compressive strength and high flexibility. An efficient method of making such strong cementitious compositions entails pre-mixing cement additives that can easily be added to a mixture of cement, silica, fibers and water. The cementitious compositions can be used to make strong, thin layers, such as tiles, that are relatively lightweight, as well as heavy structures, such as roads and bridges, without additional reinforcement.Type: GrantFiled: August 29, 2002Date of Patent: December 12, 2006Assignee: Carpentercrete, LLCInventor: Matthew R. Piazza

Patent number: RE42384Abstract: 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.Type: GrantFiled: August 4, 2010Date of Patent: May 24, 2011Assignee: Hycrete, Inc.Inventors: Eugene B.
