  • Microcapsule corrosion control in reinforced concrete
    Patent number: 8974594
    Abstract: Corrosion control in reinforced concrete is generally disclosed. Some example embodiments may include concrete including aggregate, cement, and/or microcapsules distributed within the cement, where the individual microcapsules may include a high pH salt substantially contained within an acid-soluble shell. If the pH of the concrete decreases, the acid soluble shell may swell and/or dissolve, such as below a pH of about 11, which may release the high pH salt. The high pH salt may locally increase the pH of the concrete. By increasing the pH above about pH 11, corrosion of steel rebar may be prevented and/or reduced.
