PREDICTING CONCRETE SERVICE LIFE IN CASES OF DETERIORATION DUE TO FREEZING AND THAWING. FINAL REPORT

A probabilistic procedure was developed for prediction of service life of concrete structures subject to damage due to freezing and thawing and was applied to two typical Corps of Engineers' civil works structures. These hindcast applications demonstrate the procedure and provide results encouragingly comparable to observed 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.
