Abstract:
Companion specimens of concrete made with Type I and Type K shrinkage-compensating cement were placed in andwhere they were exposed to the atmosphere approximately 50 percent of the time, and covered by seawater the rest of the time. Pulse velocity measurements made at intervals up to 9 years show no indication of deterioration. Specimens continuously exposed to the atmos- phere in the same location have somewhat lower pulse velocities, but show no deterioration..
