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.
Claims26
A method of strengthening cementitious concrete comprising:
- a. providing a section of cementitious concrete having a depth;
- b. placing a nanoparticle carrier liquid in contact with at least a first surface of said cementitious concrete section, said nanoparticle carrier liquid comprising solid nanoparticles in a colloidal suspension;
- c. inducing a current across said cementitious concrete section;
- d. applying said current at sufficient magnitude and for sufficient time that said solid nanoparticles in said nanoparticle carrier liquid migrate through at least one quarter of said depth of said cementitious concrete section, thereby increasing a strength of said cementitious concrete section by at least 25 percent.
