Manual de boas práticas para recuperação estrutural em peças submetidas à corrosão

Abstract

Armor corrosion is a pathological manifestation that compromises the building's durability and performance. The present work addresses the activities related to structural recovery in parts subjected to corrosion, such as beams, columns, slabs and reservoirs, with the objective of recognizing the pathological manifestation caused by it, which can arise from various factors such as poor execution of the work, lack of maintenance, design error, among others, identify means of treatment for reinforcement that presents corrosion and point out prevention and maintenance techniques applied to reinforcement parts that are in the process of corrosion for those structures that are compromised. Even with technological advances, the pathological manifestation remains present, causing damage to the building's useful life. The basic steps for the recovery and repair of structures with corrosion of armatures are: preliminary inspection, detailed inspection, delimitation of the area, removal of deteriorated material, cleaning, reinforcement lining, restoration of the structure and structure lining. It was observed that the time between the identification of the problem and the corrective intervention is decisive in the complexity of the procedure adopted for the recovery, requiring immediate maintenance to be carried out after the damage is identified and the repair needs to be effective and not only aesthetic for that does not compromise the residual useful life period, ensuring that the structure will still be able to perform its function.
