Estudo patológico de edificações em concreto pré-moldado em Salvador-BA

Abstract

Currently, modern constructions significantly favor the emergence of pathological manifestations due to unqualified labor, lack of knowledge about the behavior of materials and the lack of preventive maintenance. Given this, pathology consists of a science that studies pathological manifestations and their respective diagnoses, prognoses, treatment and even therapy. From this, to carry out this work, bibliographic research was carried out on the state of the art and literature on civil construction pathologies through bibliographies, technical standards, scientific articles, academic works, among others. Therefore, the present work aims to present the main pathological manifestations found primarily in facades and other structural elements in precast concrete, located in the city of Salvador-BA. Consequently, the methodology used to prepare this work consists of technical inspections of precast concrete buildings to identify the pathological manifestations found in their structures, photographs and cataloging with the aim of identifying the main anomalies present in the city studied and their possible diagnoses. Thus, it was possible to identify that the most common pathological manifestations occurring in precast concrete buildings in the city of Salvador-BA were mold, mildew and slime with the highest incidence, followed by red algae, efflorescence, carbonation, corrosion, stalactite, fissures, humidity and leaching. Finally, we concluded that the cause of most pathological manifestations may have been a consequence of humidity and lack of preventive maintenance, while the city's climatic and geographical conditions proved to be the main aggravating factors for the incidence of such pathological manifestations.
