САЖЕТАК / ABSTRACT:
The subject of the tests presented in this paper is the examination of the influence of the applied test method on the adhesion of concrete and reinforcement. In addition to the detailed characterization of concrete and reinforcement, adhesion tests were performed according to the stretching method and according to the modified Pull-out method, developed at the Faculty of Civil Engineering in Belgrade. The test were conducted on concrete samples, with centrally anchored bars with a diameter of 10 mm. The test results show that by eliminating the lateral pressures in the concrete, the achieved adhesion between the concrete and the reinforcement is significantly reduced.
