Protecting concrete reinforcement using admixture with migrating corrosion inhibitor and water-repellent component
Corrosion of embedded rebar in concrete can lead to ultimate deterioration of a concrete structure. Corrosive electrolytes and species can penetrate concrete due to its porous nature. An admixture was developed employing a synergistic blend of migrating corrosion inhibitors and waterproofing ingredients. The admixture enhances the protection by forming a protective film on rebar. In addition, it reduces ingression of water-soluble corrosive species. Electrochemical tests show that this admixture provides superior corrosion protection to the rebar. Additional test results demonstrate that the admixture reduces water permeability with no negative effects on workability set time, and mechanical properties of concrete.
