Temperature in concrete structures is of interest mainly because it is often a cause of cracking. When joints are provided in a structure, their behavior and the need for grouting are largely a question of temperature. Presented herein is the temperature history of a thin concrete dam, based on results of more than 5 years of observatron. The temperature rise of concrete is given, as well as the effect of thickness of section on temperature behavior. Also shown are graphical trends of cooling, time lag of concrete temperature behind air temperature, typical surface and near-surface temperatures; annual concrete temperature variations are given, a long with a discussion of orientation of structure and the consistent form of final temperature fluctuations.
