Abstract:
Internally cured concrete was used to repair bridge decks of the Wilson Dam in Muscle Shoals, AL, USA, and to provide a 100-year service life. The article discusses characteristics of internally cured concrete and the benefits of using it, as well as lightweight aggregates needed to produce such concrete and their properties.
