On the mapping of reinforced concrete pillars with pathological manifestations: Case in buildings belonging to a public university

Abstract

This work is a case study through the mapping of pathological manifestations identified in reinforced concrete pillars of buildings belonging to the Faculty of Science and Technology at UNESP (FCT/UNESP), located in Presidente Prudente, São Paulo. In the field, a survey of anomalies in the buildings under study was carried out using digital images. The information obtained was gathered and organized with the respective locations on campus of the collected images and captions that indicate the type of anomaly present – ​​crack, stain, spalling, exposure of corroded reinforcement or niche –, through different shapes and colors. It was then analyzed, with the aid of a quantitative graph, that the types that appeared most frequently were exposed reinforcement with corrosion, cracking and spalling, showing that maintenance and/or repair programs must be carried out.
