PATOLOGIAS E INSPEÇÃO DE UMA CONSTRUÇÃO EM CONCRETO ARMADO: estudo de caso em um tanque de armazenamento de solução sulfato de zinco

Abstract

In the industrial sector, reinforced concrete is a widely used material, offering great benefits in terms of costs, safety, durability and aesthetics. Like all construction materials, it requires conservation and maintenance, and one of the biggest challenges related to it is to

reduce repair costs and avoid losses in the construction's durability, aesthetics and safety. Reinforced concert constructions are subject to pathologies during and after completion, some of which can be visualized by the human eye. In the industrial environment, the durability of concrete structures tends to be due to the less aggressiveness of the agents present in these environments. The work comes as a way of showing the importance of identifying and acting on the pathologies found in the reinforced concrete tank used to store zinc sulfate solution, minimizing major future problems. The methodology used to visualize and identify pathologies in the tank was through visual inspection and recorded via photographic survey. Registered as pathological manifestations, they were scientific and given a technical opinion on the probable causes of the appearance, then corrective and preventive maintenance actions were proposed based on the fundamental cause seen on site. The manifestations were cracks, reinforcement corrosion, efflorescence, infiltration stains and disintegration. The main causes for the manifestations were low surface recognition, low design fck, high aggressive environment, lack of waterproofing and leaks. As a result, the importance and need for corrective and preventive practices were highlighted before they became more serious.
