• 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 quality final ; product. Insufficient curing of concrete will cause cracking in the concrete and in turn leads to a non-durable ; and non-sustainable concrete structure. Current Louisiana specification requires all concrete decks to be ; water cured for 10 days. Based on the field experience, this is a very expensive operation and the most ; difficult 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. ; This project was undertaken to quantify and document the beneficial use of internal ; curing via saturated lightweight aggregate fines.
