Abstract
The results of a preliminary study of the bond strength of epoxy-coated and uncoated plain and deformed wire are reported. Bond strength is evaluated using 25 beam-end specimens containing Wll and Dll wire with 3f4 in. or 2 in. (19 mm or 51 mm) concrete cover. Epoxy coating appears to increase the bond strength of plain wire, while having only a small effect on the bond strength of deformed wire. The tests indicate that epoxy may actually increase the bond strength in cases of high confinement while slightly decreasing the bond strength in cases of lower confinement. The bond strength of both coated and uncoated deformed wire is significantly higher than the bond strength of either coated or uncoated plain wire.
