Abstract:

Internal curing has recently been developed as a new concrete technology that has the potential to dramatically extend the service life of concrete infrastructure elements like bridge decks. Internal curing uses prewetted lightweight aggregate in low water to cement ratio, high performance concrete to provide curing water at the opportune time to minimize restrained shrinkage cracking and increase hydration of the cement resulting in reduced chloride ingress and corrosion. Internal curing may be able to extend the service life of a concrete deck. The benefits of internally cured concrete bridge decks (either new or replacements) at a system level, in the context of traffic disruptions resulting from renewal/repair needs and varying traffic flow congestion levels across different timescales, is a relatively unexplored concept. This research seek to understand the potential benefits of internally cured concrete mixtures compared to conventional mixture in a transportation system, thereby filling a key gap in the current internal curing literature.
