Procesures for Evaluating Corrosion - Inhibiting Admixtures for Structural Concrete
SUMMARY
PROCEDURES FOR EVALUATING CORROSION-INHIBITING
ADMIXTURES FOR STRUCTURAL CONCRETE
During the past fifteen years, corrosion-inhibiting admixtures (CIAs) have become
increasingly popular for long-term protection of reinforced and prestressed concrete
components of highway bridges and other structures. However, there remains
considerable debate about the benefits of CIAs in concrete. The objectives of this
research were to (1) develop procedures for evaluating and qualifying corrosioninhibiting
admixtures and (2) recommend performance criteria for their acceptance.
Phase I work included a literature review of CIAs, the review of test procedures
presently used for evaluating CIAs, and the development of a laboratory test plan for
evaluating CIAs. In Phase II, the laboratory test plan was executed and performance
criteria for qualifying an admixture as a CIA were developed.
The following corrosion inhibiting admixtures (CIAs), which are available
commercially, were identified. Based on proposed mechanism of protection, they were
combined into four groups.
