| Abstract | This study presents the bond behavior between the geopolymer concrete and steel bar. A total of thirty-six cube samples were performed with the direct pullout test. Three variables are considered in this study including the type of steel bars (round bar and deformed bar), the embedment lengths (5, 7, and 9 times the bar diameter), and the type of concrete (normal concrete with compressive strength of 30 MPa and geopolymer concrete with compressive strength of 30 and 40 MPa). The effects of these variables on the bond strength and maximum shearing stress are discussed as well as the failure mechanism. Based on the test results, the bond strength of deformed bar specimens is higher compared to those of round bar specimens. The compressive strength of geopolymer concrete has no significant effect on bond strength. However, pull-out failures are found in all specimens. |
