On April 6, 2009, a 3-ft × 3-ft section of a closure pour in a reinforced concrete deck on Interstate 81 punched through. The deck had been cast in 1992 during a deck replacement project in which each lane and shoulder of the deck was replaced while

Two types of linear polarization devices may be used to measure the corrosion current density (CCD) to assess the degree of active corrosion in concrete structures. The devices, with and without a guard electrode, provide significantly different CCD

During its service life, concrete experiences volume changes. One of the types of deformation experienced by concrete is shrinkage. There are four main types of shrinkage associated with concrete: plastic, autogenous, carbonation, and drying shrinkag
