Abstract
A method of inhibiting corrosion of metal reinforcement structures embedded within cured concrete. The method comprises providing a plurality of exteriorly-accessible generally uniformly distributed openings in the concrete. Thereafter, a plurality of containers is provided, with each container having therein a migrating corrosion inhibitor and having a wall structure which is permeable to the migrating corrosion inhibitor. One container is placed in each of a sufficient number of openings in the concrete such that a sufficient quantity of migrating corrosion inhibitor exits from the respective containers and migrates through the concrete to the embedded metal reinforcement structures to thereby inhibit corrosion.
