| description | Ultra-high-performance concrete (UHPC) is an advanced, durable cementitious material with excellent mechanical
properties, which makes it an appropriate material for strengthening, repair, and retrofitting of damaged concrete structures.
The UHPC as a repair material on normal strength concrete (NSC) depends on the quality of the bond strength at the
interface. The interface behavior of UHPC-NSC concrete has a significant impact on its overall durability performance.
This paper reviews the studies conducted on the bond strength at the concrete interface to determine the effectiveness of
different bond strength testing techniques. The review has shown that the bond strength is commonly evaluated through
splitting tensile, slant shear, direct shear, pull-off, bi-surface shear, and third-point flexural tests. Slant shear and splitting
tensile test methods are the most common techniques used to evaluate the performance of bond strength between UHPC
and NSC. splitting tensile tests, stress is directly applied at the concrete interface, while in the slant shear test, the interface
surface is subjected to combined compressive stress and shear stress. Thus, Splitting tensile tests produces more accurate
results than the slant shear test. Bi-surface shear and third-point flexural tests are easy to conduct and give a result similar
to splitting and direct shear tests. However, further investigations are required on the reliability of the test methods under
different conditions. In terms of failure modes, splitting tensile tests produces a more consistent result compared to the pull-off test. |
