İnvestigation of chemical anchorage performance of polmeric rebar

As a result of the fact that the building elements are unable to perform the carrying power in some cases, the need for reinforcement occurs. Although there are several methods in strengthening structures, one of the most commonly used stages is the method of anchoring the concrete of its equipment with what is known as sprout cultivation. Construction steel is usually used as anchorage element in retrofitting operations and is preferred for repair and strengthening existing structures due to high adhesion resistance due to ribbed effect. As an anchorelement, construction steel is used in the holes opened later on to the existing concrete, using chemical adhesives and planting sprouts. When examining the structures that need strengthening in our country, it is seen that serious problems occur in the structures due to both abnormal environmental conditions and the corrosion of steel equipment in the reinforced concrete element. For this reason, when studies in this field are examined in this field, it is important in recent years to investigate the performance of different types of composite equipment, which may be an alternative to corrosive effects, in order to be a solution. is seen. Today's civil engineering structures are preferred not only for metallic but also for their polymeric equipment, for durability reasons. However, it has not been fully demonstrated in the studies of how these materials behave in chemical anchorage applications such as steel reinforcements. In this thesis study, polymeric equipment (GFRP) of different diameters made of glass fiber, which has been used in mosques, especially coastal structures, ground and field concrete, which has been widely used in tunnels, has been with higher strength and corrosion resistant in recent years. steel (ST) and basalt equipment (BFRP) and anchor aderans resistance resistance sequentive sequentive resistance. Performance research was carried out with axial extraction experiment on experimental samples of different diameters and different depths. The adhesion strengths and stripping values of these 3 different types of equipment, which are placed on the concrete afterwards and manufactured on low-strength and normal strength dwelling concreteusing uniform adhesives, are calculated separately with graphs has been put forward. According to the findings, the aderansity resistance decreased as anchorage equipment increased during the clamping length. In addition, polymeric equipment has a better anchorstrength than the rebar. As with steel equipment, polymeric equipment has been observed to vary depending on the size of the equipment, the concrete class and the depth of the burial. On low-strength concretes, the amount of load required to remove Ø14-diameter equipment from the concrete was found to be approximately 11% less in polymeric equipment (GFRP), steel equipment (ST), and 6.4% more in Ø20-diameter equipment. Similar characteristics have been detected on normal strength dwelling concretes.
