Estilhaçamento do concreto em situação de incêndio: o estado da arte

Abstract

Modern concretes are increasingly prone to a failure phenomenon known as concrete spalling, induced by heat. This phenomenon is characterized by the sudden loss of material during intense thermal exposures, such as those occurring during fires. Typically, this type of failure is violent and can result in significant loss of the structure’s cross-sectional area, direct exposure of internal steel reinforcement, and, in extreme cases, structural collapse. The present study is dedicated to the analysis of this phenomenon, exploring the knowledge available in the literature. Initially, the goal is to understand spalling, its dynamics, and the main theories that address it. Subsequently, recently published works are explored to understand the directions in which research is advancing and to identify possible solutions to mitigate this problem.
