The repair and maintenance sector of the construction industry has become a growing sector in recent years. In the market there are many repair systems which has made the choice of the appropriate system very difficult. As far as the repair is concerned, chieving a good bond between the repair and the original concrete is essential. To date a few methods of testing the bond strength between the repair and original concrete have been suggested but mainly these are tests which must be carried out under laboratory conditions. In addition there is the question of the applicability of laboratory test results to actual site conditions. This paper describes insitu testing methods which can be used to determine the tensile and shear bond strengths between the repair and original concrete. Comparisons have been made between these methods and a compression/shear method.
