Mitigation Techniques for In-Service Structures with Premature Concrete Deterioration

This thesis describes part of the work associated with Texas Department of Transportation Study 4069 (“Mitigation Techniques for In-Service Structures with Premature Concrete Deterioration”). The Texas Department of Transportation is interested in developing techniques for mitigating or remediating premature concrete deterioration due to alkali silica reaction (ASR), delayed ettringite formation (DEF), or both, in order to extend the life of potentially affected structures. The parts of Study 4069 reported here consist of: a review of existing test methods for possible application to evaluate mitigation treatments; development of a new test method, if necessary; verification of the The degree sought must be the abbreviation of the proper name as listed in The Graduate School Catalog, such as Master of Fine Arts (M.F.A.), Master of Science in Engineering (M.S.E.), Master of Public Affairs (M.P.Aff.), Master of Education (M.Ed.), Master of Arts (M.A.), etc. test method; application of the selected test method to evaluate mitigation treatments; and recommendations of specific treatments to mitigate premature concrete deterioration from ASR/DEF.
