Using CSA Cement for Novel Waterway Repair Materials

The health and performance of maritime transportation infrastructure is critical to the nation’s economic and social prosperity. Much of this infrastructure has well exceeded its 50-year design life and is often in need of repair. Because waterway transportation structures are difficult to detour, the time taken by repairs is of critical importance. The fastest repair techniques should be developed in order to minimize the time out of service. The objective of this research is to investigate the properties and behavior of Calcium Sulfoaluminate-Belite (CSA) cement mixtures for waterway repair applications. CSA cement is a rapid setting, low-shrinkage cement which can be used to form advanced new materials capable of quickly repairing the nation’s maritime infrastructure. CSA cement maintains many of the beneficial qualities of portland cement but it can reach structural strengths in only a few hours and its low shrinkage makes it an ideal repair material
