Análise do processo de recomposição em vigas de concreto armado com reforço de fibra de carbono

Abstract

Reinforced concrete structures can suffer pathologies during their useful life, due to design flaws, inadequate execution of the work, incorrect use, among other reasons. Among the pathologies, the most common on site is reinforcement corrosion. With this occurrence, measures to recover the damaged structure must be executed. For the recovery of the structural element, the most used technique is the treatment of the reinforcement and subsequent repair of the structural element and, when necessary, reinforcement should also be made. The following work presents a study with the objective of evaluating the process of recomposition of structural elements in reinforced concrete, as well as the performance of the materials: concrete, grout and structural adhesive in the recomposition of beams. The effectiveness of carbon fiber as a structural reinforcement will also be tested. To carry out the analyses, tests will be carried out in the laboratory on reinforced concrete beams, divided into groups, where each group uses a different type of material or process. After the analyses, conclusions will be made about each material.
