New York State Uses Internally Cured Concrete to Reduce Cracking and Extend Service Lives of Bridge Decks
"The New York State Department of Transportation (NYSDOT) fully institutionalized the use of ICC in 2017 by requiring it on all new bridge decks for multi-span bridges. In 2024, they updated their specification to extend ICC for use in all bridge decks."
"Enhancing Performance with Internally Cured Concrete (EPIC2) increases resistance to early cracking and allows production of concretes that may last more than 75 years. This innovation builds upon extensive studies over the last 30 years that show internal curing addresses the root cause of shrinkage cracking. Internally cured concrete (ICC) has extra water in the concrete mix that becomes available as the free water in the mix is used up during curing. ICC accomplishes this by including materials in the mix that initially absorb water but then release it during the concrete hydration process."
