  • Electrokinetic strength enhancement of concrete
    Patent number: 9487450
    Abstract: A method and apparatus for strengthening cementitious concrete by placing a nanoparticle carrier liquid in contact with a first surface of a concrete section and inducing a current across the concrete section at sufficient magnitude and for sufficient time that nanoparticles in the nanoparticle carrier liquid migrate through a significant depth of the concrete section.
    Type: Grant
    Filed: January 23, 2013
    Date of Patent: November 8, 2016
    Assignee: LOUISIANA TECH RESEARCH CORPORATION
