Análise das manifestações patológicas em estruturas de concreto armado na cidade de Guamaré-RN

Abstract

The present work aims to investigate the motivation of the main pathological manifestations resulting from the influence of the marine environment on the buildings of the seaside county called Guamaré / RN. Salt air is a characteristic feature of coastal regions and needs to be taken into account when building. Formed by a humid mist composed of salts from the sea and carried by the winds, the sea air settles on the building surfaces, generating chemical reactions. This phenomenon is the main generator of pathologies by corrosion of the reinforcement, due to the large chloride content present in the water particles. This work uses bibliographic surveys in articles, monographs and norms of the Brazilian Association of Technical Standards, in order to obtain the proper theoretical basis. Through photographic analysis, on-site testing and verification of the coverings of structures with exposed reinforcement, the importance of the technological control of the materials when building was verified, as well as following the recommendations of the Brazilian Association of Technical Standards, in order to guarantee the durability of the buildings, thereby reducing repair costs.
