Original Abstract

Several very large and tragic fires of buildings have occurred recently, drawing attention to the issues of fire resistance of buildings (especially high-rise buildings and tunnels) and of building materials. For cement-based composites, it is essential to comprehensively understand the behaviour of their internal structures when exposed to high temperatures. This paper deals with the changes of the physical properties of concrete with different aggregate grain sizes when exposed to high temperatures. The emphasis is placed on the changes of the static and dynamic modulus of elasticity as an important parameter in assessing the behaviour of structures or their parts. During the test of the static modulus of elasticity, the acoustic emission method was also used as its results may reveal the behaviour of the internal structure of the material during mechanical loading.
