scope:

This study comprise one element of research being conducted by the U.S. Army Corps of Engineers to develop innovative materials and systems for economical and durable maintenance and repair of concrete structures.

Based on the cost of repairing the country's aging infractructure (estimated to be in excess of $1 trillion), an explosive growth in concrete technology is occuring. Much of this emerging technology appears to be sound. However, its potential for use by the Corps needs to be evaluated and adapted as necessary before being adopted for widespread use. Without innovations in concrete technology, the Corps will be forced by decreasing resources to reduce the scope of its maintenance and repair programs, possibly jeopardizing the future operation of civil works structures.

This research focuses on the use of controlled-permeability formwork for high-strength, durable, aesthetically pleasing concrete structures.
