Selecting the cement to be used in a concrete can have a lasting impact on the life span of new concrete bridge decks. One option that is underspecified but has a host of proven results is special cement. There are many situations in which these cements can help extend the useful life cycle of concrete bridge decks.

Indeed, most of the almost 350,000 concrete bridges in the country have concrete decks that develop avoidable premature cracking due to initial shrinkage soon after the pour. While the useful life of structural concrete can exceed 50 years, premature cracking on these outdoor installations frequently warrant early repair.
