Behaviors of Chemical Anchors Installed in Different Types of Concrete

Chemical anchors are widely used in additional installations of construction irons, repair and reinforcement work. Due to the increasing diversity of materials and the improved awareness of waste products, it has become possible to produce different types of concrete with various characteristics. In this study, class B420C ribbed bars with 16 mm diameter were installed in four different concrete types by using four different chemical adhesives, and a tensile force was applied. The stiffness, displacement ductility ratio, energy-absorbing capability and tensile force values were determined and the failure modes were interpreted from the load-displacement curves obtained as a result of the experiments. It was observed that tensile force and energy-absorbing capacity had increased as a result of installing anchor and applying a tensile force to the concrete that was obtained by adding admixture materials to the reference concrete. In the analytical part of the study, the formulation provided in ACI 318 was used, capacity and design strengths were identified, and their safety levels were determined in comparison with the test results.
