| Abstract: |
This paper summarizes an experimental study designed to evaluate the bond characteristics of the plain round bars in low strength concrete of less than 10MPa. A total of 161 pull-out tests were performed to examine the bond strength and the effect of repair with the epoxy resin injection method. The strength levels of the manufactured concrete were between 5 and 8MPa. The other variables were the direction of the steel bars, the thickness of the concrete cover under the bar etc. The test results show that the approximate bond strength of plain bars in low strength concrete was much lower than the allowable design strength in Japan and that the bond strength of plain bars was significantly increased with the injection of epoxy resin. |
