  • Abstract:
    Proper curing is the key to durable and sustainable concrete structures. When a concrete mixture is designed, delivered, poured, and consolidated, curing is the last and the most critical part for a fi nal product of great quality. Insuffi cient curing will cause cracking in the concrete and, in turn, leads to a non-durable and sustainable concrete structure. Current Louisiana specifi cation requires all concrete decks to be water-cured for 10 days. Based on fi eld experience, this is a very expensive operation, and the most diffi cult one to enforce and monitor. Therefore, there is a great need to develop a new concrete mix that has a self-curing capability, which will reduce the time demand for water curing, minimize or eliminate cracks in the concrete deck, and help achieve durability and sustainability in concrete structures.
