The reinforcement properties of the test rebars were shown in Table 3. The yield and ultimate strengthof rebar were obtained from typical tensile strength test. At least 5 rebars from the same batch of thoseused in pull-out test were selected in this tensile strength test. Only average values were presented herein the table.In this pull-out test, the universal testing machine as shown in Figure 3 and 4 was used underdisplacement-controlled procedure. The concrete cubes were rested against steel plate and allowing therebar penetrating through the hold as shown in Figure 4. The bottom grip was used to hold the tip ofthe steel bar tight and gradually pull it down. The pulling force and bar slip at the end of the cube weremonitored throughout the test.
