Abstract:

On April 26 and 27, 1999 a workshop on Predicting the Performance of Concrete Repair Materials was held at the New England Conference Center in Durham, New Hampshire. This workshop was a follow up of a previous workshop held in 1995 at the National Institute of Standards and Technology which dealt with research needs to minimize cracking in concrete repair materials. The focus of the 1999 workshop was on test methods and modeling techniques for predicting the performance of concrete repairs. The two-day workshop included a half-day of presentations to define the problems and review current knowledge. The presentations were followed by working group sessions on the following topics: (1) modeling material performance; (2) repair design, specification, and application; and (3) repair materials and systems. The conclusions of the working groups were presented at a plenary session on the second day. The workshop concluded with recommendations for action. This report provides summaries of the working group discussions and concludes with the recommended actions.
