Abstract
This paper describes the test results of the pullout test in order to obtain the local bond behavior between Engineered Cementitious Composites (ECC) and steel reinforcing bar. There is a possibility that the size of cover thickness of ECC around reinforcing bar affects the orientation of fiber, so bridging performance of fiber is influenced by specimen size. To evaluate size effect, the main parameters of specimens are reinforcing bar diameter and cover thickness. The shape of specimen is a similarity shape based on reinforcing bar diameter. From the test results, bond strength tends to increasing with cover thickness. Moreover, bond strength decreases with increasing reinforcing bar diameter. To evaluate size effect, cylindrical volume around reinforcing bar is defined as highly-stressed volume. As for specimen of each cover thickness, the normalized bond strength decreases with increasing of highly-stressed volume.
