Manifestações patológicas no Estádio Municipal Carmelito Barbosa Alves, Cruz das Almas-Ba

Abstract

Concrete structures and buildings in general are subject to the action of several agents that accelerate the degradation process. Identifying these factors and acting to mitigate the harmful process on buildings is essential to ensure their durability. In civil engineering, the pathology of buildings is the field that studies the symptoms, mechanisms, causes, origins and consequences of pathological manifestations in buildings. In this perspective, the present work presents a verification of the pathological manifestations that affect the Municipal Stadium Carmelito Barbosa Alves, Cruz das Almas. The evaluation was carried out by means of semi-destructive tests using phenolphthalein and non-destructive solutions such as Unmanned Aerial Vehicles (UAVs), or drones, to obtain images in difficult to access places (such as metal towers) and direct observation of the structure. This observation was guided by a list with the main pathological manifestations that affect the concrete, among them: segregation, leaching of hydrated compounds, cracks, signs of corrosion of the steel in the slabs, beams and columns, concrete detachment, reinforcement exposure and verification of the reinforcement cover in beams, columns and slabs. The results indicate the presence of beams with cracks associated with the flexion of the part, exposure of reinforcement in slabs and columns, insufficient covering with carbonation reaching and de-sparing the steel, as well as inadequate reinforcement spacers.
