Control of ConCrete CraCking in Bridges Many advances in bridge design, concrete technology, and reinforcement materials have been made over the years. Nevertheless, cracking of concrete in bridges continues to be a concern for bridge owners, particularly in bridge decks exposed to severe environments.

2 Practices that show potential for reduction of shrinkage and shrinkage cracking include the use of supplementary cementitious materials, internal curing, shrinkage-reducing admixtures, or shrinkagecompensating concrete. End zone cracking, which occurs in prestressed concrete beams, is an uncommon occurrence and often can be prevented by revising the detensioning sequence.
