- Chemical Compatibility Between Concrete Repair Materials and ASR Affected Concrete
Chemical Compatibility Between Concrete Repair Materials and ASR Affected Concrete
Project ID: 8126
Principal Investigator: Westin Joy
Research Topic: Repair and Maintenance
Funded Fiscal Years:
2018,
2019 and
2020
Keywords: None
Research Question
Would alkalis in repair materials accelerate the ASR reaction at the interface and lead to deterioration of bond strength?
Need and Benefit
Reclamation's aging infrastructure is in constant need of repair. Concrete repairs can last the remainder of the structures service life if the repair material is compatible with the existing substrate. Often times, the concrete repairs are shorter lived (5-10 years if that) because the repair material is not compatible with the existing concrete substrate. At Boysen Dam, the Concrete, Geotechnical, and Structural laboratory group is seeing repairs that were performed in 2001, that already need replacement.
