Retração e secagem do concreto : estudo da retração do concreto e o aparecimento de patologias

Abstract

Since the reinforced concrete structures are the most used constructive method in Brazil, there are a large number of Brazilian buildings that present pathologies. This work aims to analyze the most frequent pathologies in reinforced concrete structures, focusing on the pathology caused by concrete retraction, the main features of this pathology, and the methods used to cure it, based on publications and scientific works, as well as experiences of professionals specialized in the subject in order to contribute to the technical knowledge regarding the pathologies in the structures of reinforced concrete. The pathological manifestations cause inconveniences not only for the client, but also for the constructor, since the costs of an eventual intervention after a work delivery are greater compared to the costs of a well-executed execution. In this way, this work sought to identify the most common pathologies in reinforced concrete structures, passing through linear cracks arising from concrete retraction, reinforcement corrosion and thermal variations.
