Behaviour of Concrete Under Direct Fire

Abstract

Behaviour of concrete structures in fire relies upon several elements. These consist of change of material property because of fire, temperature distribution in the elements of the buildings, details of reinforcement, severity of exposure and duration. This paper discusses the outcomes of increased temperatures on concrete. The goal of this paper is to provide a high-level view of results at improved temperature of the behaviour of concrete elements and systems. The main goal of this research work is to summarize the properties of concrete at rising temperature. The properties of conventional concrete and the properties of high strength concrete subjected to elevated temperatures compared. Fire reaction of concrete structural participants is depending on the thermal, mechanical, and deformation properties of concrete. These properties vary drastically with temperature and additionally rely on the composition and characteristics of concrete batch mix in addition to heating rate and different environmental situations. The variation of thermal, mechanical, deformation, and spalling residences with temperature are defined
