Bond of reinforcement in eccentric pullout silica fume concrete specimens
Abstract The objectives of the study were to investigate the role of specimen type and specimen size on the effect of silica fume on bond strength of reinforcing bars, and to evaluate the effect of bar size and concrete confinement on the anchorage characteristics of the reinforcing bars in silica fume concrete. Forty-eight eccentric pullout specimens were tested. The variables were the percentage replacement by weight of cement by silica, the concrete cover over the reinforcing bar, and the bar size. Failure of the specimens was governed by splitting of the concrete cover over the anchored bar. Test results indicated that as the percentage of silica fume increased, the maximum load capacity and the stiffness of the load-slip curve of the anchored bar decreased, regardless of bar size or the concrete cover used. The results showed that concrete confinement slightly improved the bond resistance in concrete containing more than 10 percent silica fume.
