Book Description
Prefabricated epoxy-coated reinforcement is used increasingly in reinforced concrete construction in which high corrosion resistance is required. It is well established that epoxy coating reduces bond strength between reinforcement and concrete, and some tests have found that bond strength decreases as coating thickness increases. For prefabricated epoxy-coated reinforcement, it can be difficult to maintain coating thicknesses within required tolerances 175 to 300 im. Beam-end tests were carried out on uncoated bars, bars with green epoxy coating (203 im coating thickness), and prefabricated (gray) epoxy coating (203 to 508 im coating thickness). Tests showed that epoxy coating reduces bond strength, with similar reductions for green and gray coatings. In some cases, bond strength decreased with increasing coating thickness, but for the range of thicknesses investigated the reduction factor of current building codes was found to be conservative

Book Description
"In 1993, the CEB Commission 2 Material and Behavior Modelling established the Task Group 2.5 Bond Models. It's terms of reference were ... to write a state-of-art report concerning bond of reinforcement in concrete and later recommend how the knowledge could be applied in practice (Model Code like text proposal)... {This work} covers the first part ... the state-of-art report."--Pref.

Book Description
Fusion-bonded epoxy coating is extensively used to enhance the corrosion resistance of reinforcing steel. The bond strength between these bars and the concrete is expected to be less than that of the uncoated bars and it may be further impaired due to prolonged exposure to thermal variations. This investigation was conducted to evaluate the effect of thermal variations, simulating the changes in the night to day temperature, on the bond strength of fusion-bonded epoxy-coated steel reinforcement. The pull-out specimens, prepared using bars of two different sizes and two coating thickness, were exposed to thermal cycling. The critical and ultimate bond strength of the fusion-bonded epoxy-coated bars were compared with that of the uncoated bars. The results indicated a reduction in the critical bond strength between concrete and the fusion-bonded coated bars. Furthermore, the difference between the critical bond strength in the coated and uncoated bars decreased with increasing thermal cycles, indicating that thermal variation has a greater effect on bond strength than the coating thickness.
