This thesis researches bond characteristics between the 12mm steel reinforcing bar and
various types of concrete. Standard Eurocode 2 and FIB Model Code 2010 define ultimate
bond stress, which acts like shear stress around the reinforcing bar. In correlation with bond,
high strength concrete is poorly represented, furthermore, research and information on fibre
concrete are lacking. Therefore, a series of pull-out tests, based on standard SIST EN
10080:2005, have been conducted. In this study, behaviours of normal strength concrete,
high-strength concrete and high-strength steel fibre-reinforced concrete with 1 % of steel
fibres have been tested. Three pull-out tests were carried out for each type of concrete. The
results show that high-strength concrete acts in similar way as normal strength concrete.
However, its ultimate bond stress was three times larger.
