Abstract:
An arch-gravity roller-compacted concrete (RCC) dam on the Gomal River, Pakistan, was built from 2008 to 2012. Temperature control measures were required during construction to prevent thermal cracking of RCC in hot weather. The article provides detailed descriptions of these measures, specifically the precooling of aggregates and mixing water and post-cooling of the placed RCC.
