Approximately one-third of the locks and dams owned and operated by the U.S. Army Corps of Engineers are more than 40 years old. Many of these structures are well beyond their original design life and with the relatively limited number of new construction starts anticipated, the number of projects in this category will continue to increase. In response to this situation, the Corps initiated the Repair, Evaluation, Maintenance, and Rehavilitation (REMR) Research Program to develop effective and affordable technology for maintaining and, where possible, extending the service life of civil works structures. The research program is divided into seven problem areas of which concrete and steel structures is the largest representing approximately 30 percent of the total research effort. Results to date of 13 individual research studies within the problem area that relate to concrete are described in this paper.
