Effect of Epoxy Coating on Bond and Anchorage of Reinforcement in Concrete Structures
The objective of the research program was to assess the influence of epoxy coating on the bond characteristics of reinforcing bars and to develop or revise the existing recommendations for the design of splices and anchorage of straight and hooked epoxy-coated reinforcement. Three different series of tests were conducted. Pullout specimens were tested to determine differences in stress transfer between normal mill scale uncoated and epoxy-coated bars using different bar sizes, coating thicknesses, bar deformation patterns, rib face angles, concrete strengths, and different levels of restraint to splitting. Twelve beams with splices in a constant moment region were tested in negative bending. A comprehensive review of the effect of epoxy coating on structural aspects of coated bars was performed. From the review, design procedures were recommended for coated straight and hooked bars.
