Abstract: Engineered cementitious composite (ECC) is a new type of concrete material, which has the characteristics of strain hardening and multiple cracks. Its application in engineering practice can significantly improve the mechanical properties of structural members. The bond performance between steel bar and ECC is the basis of their joint work. Therefore,the influence of steel bar diameter, embedment length and cover depth of steel bar and ECC through central pull-out test are studied.The test results show that the change of bond length has different effects on the bonding performance of the two surface forms of steel bar. The specimens with different thickness of protective layer have different failure modes, and the ultimate bond stress will increase significantly with the increase of fiber content.

Key words: engineered cementitious composite, center pullout test, bonding performance
