Abstract:
A series of tests was made of the effect of age on the factors controlling bond resistance in the adhesive and frictional stages. Test specimens of the pull-out type utilizing machined polished bars were employed together with some specimens in which the bond resistance was broken down by the application of a torque to the steel. It was found that bond resistance grows rapidly and at a much greater rate than the compressive strength of concrete. It is suggested that bond resistance is dependent only to a minor degree on the strength of the concrete.
