Abstract:

The importance of the bond strength of a multilayer concrete system is increased with the increase of the use of the advanced composite materials of different bases in the field of repair or strengthening. Experimental and analytical models based on different testing methods are developed in attempt to evaluate the actual bond strength of the system. The most commonly used techniques to prepare the interfacial bonding surface and the relative strength of the concrete system are considered of the dominant factors that govern the structural behaviour of the concrete system. Therefore, it was the motivation of the author to examine the influence of those two factors on the shear bond strength resulted from implementing the slant shear test. The results of the presented research work show the role of the direction of roughening the surface and the mechanical bonding on the shear bond strength. A simplified and reliable formula was presented to predict the shear bond strength in terms of the surface condition and the relative strength value.
