Repair, Evaluation, Maintenance, and Rehabilitation Research Program: PredictingConcrete Service Life in Cases of Deterioration due to Freezing and Thawing

摘要

A probabilistic procedure was developed for mathematical prediction of servicelife of concrete structures subject to damage due to freezing and thawing and was applied to two typical Corps of Engineers' civil works structures, dams and waterways locks. These hindcast applications demonstrate the procedure and provide results encouragingly comparable to observe deterioration. The sensitivity of the results to key material and environmental variables is discussed. Current testing procedures relevant to service life prediction are discussed along with recommendations for improvements in these areas.
