Internally Sealed Concrete Using Wax Beads


The use of wax beads to internally seal a concrete bridge deck to reduce the intrusion of chloride for the protection of the reinforcing steel is reported. Test panels of the internally sealed concrete were constructed to determine the best heating method and amount of time required to melt the wax beads. The test panel and bridge deck mix design, construction, heating, and evaluations are documented. The low chloride content test and low half cell potential tests indicate that the Internally Sealed, Wax Bead Concrete is performing as designed.
