SERVICE LIVES OF CONCRETE SEALERS

Approximately 16 generic types and more than 450 concrete sealers are used as corrosion protection agents in the United States. However, no standard performance criteria that can be used to determine the cost-effectiveness of the various sealers exist. A study was performed to address the determination of the service lives (reapplication period) of sealers for concrete bridge components in the United States. The environmentally degrading forces of ultraviolet light and abrasion are considered, as is the leakage of the chloride ion through sealed concrete surfaces. A methodology is presented to determine sealer reapplication periods on the basis of the severity of the chloride exposure conditions, bridge site chloride diffusion rates, concrete cover depths, selected corrosion initiation protection period, and chloride leakage factors. The methodology is combined with a laboratory test method to determine sealer leakage factors, and sealer service lives are estimated for a water-based and solvent-based epoxy, a silane, and a siloxane for horizontally and vertically oriented concrete bridge components.
