METHOD FOR TENSION- SHEAR STRENGTH (BOND STRENGTH) TESTING OF ANCHORAGE USED FAST CURE ADHESIVES

In the paper several factors which have significant influences in identifying fast cure adhesive (FCA) bond strength as specified in the new version of the "Design code for strengthening concrete structures" are carefully studied through tension test. Totally 51 specimens with two typical FCA materials were tested to explore the influence of rebar and rod, thread detail of the inner surface of sleeve, and curing time. The failure mode identification is also discussed based on the test results. The findings could be helpful for achieving a more accurate test identification of bond strength of FAC materials.
