Recuperação de estrutura de concreto armado : ETA Duque de Caxias/RJ

Abstract

Concrete structures have a useful life, as do all materials incorporated in civil construction. There are numerous factors that influence the loss of performance of reinforced concrete structures, which can result in major problems. The structural elements under study suffered, over the years of work stoppage, problems of corrosion of exposed reinforcement without adequate protection, infiltration processes, humidity and cracks, deficiencies in the design and execution of the work, in addition to factors caused by third parties, not anticipated when carrying out the work. The study of the pathology of engineering structures is extremely important and aims to improve the performance of reinforced concrete structures throughout their useful life. To recover the concrete structure and continue the work, specific procedures must be carried out in order to increase the safety and useful life of these structures, in addition to preventing the deterioration of the concrete and reinforced reinforcement.
