Chloride transport and shrinkage of plain and internally cured concrete

TL;DRAbstract

Concrete bridge decks are susceptible to premature deterioration which may be caused by cracking of the concrete and corrosion of reinforcement. While engineers strive to design bridge decks to have high performance, it has become evident that mixtures that may lead to high strength and low transport properties (i.e., so called high performance concrete) may also have a potential to exhibit increased cracking. Recently, there has been an interest in developing mixtures that also strive to minimize the potential for cracking while providing a dense microstructure that reduces the potential for chloride ingress. Over the last fifteen years there has been growing interest in exploring the use of internally cured concrete since it minimizes early age volume changes and corresponding cracking. While the original intention of using internal curing was to reduce autogenous shrinkage, it has been observed that the internally cured concretes have additional benefits.
