Evaluation of Mechanical Properties in Concrete Structure Reinforced with Carbon Fiber Coating

Abstract:

In this study, it was possible to evidence the efficiency of the use of carbon fiber coating in concrete structures and its application to promote the protection and maintenance of these materials, seeking to prolong the useful life of this type of structure. From mechanical tests, such as compressive strength, it was possible to observe an increase of 37% in the breaking load, as well as an increase of about 40% in compressive strength, when compared to tests with pure concrete. Therefore, the results pointed to the optimization of the mechanical properties of the structure, coated with carbon fiber and cured with epoxy resin. In other words, the use of this external load combined with epoxy resin was an important element in concrete reconstruction and reinforcement. Another interesting point was the issue of the high fiber rigidity observed in the AFM, allowing an excellent interaction with the resin in the coating of the specimen. The study showed that this type of coating can be used for the recovery of structures, as well as a reinforcement element, since many projects have difficulties with the high maintenance cost, as well as the daily monitoring of concrete structures.
