摘要： 混凝土结构在遭受火灾作用后,在决定修复受损结构之前,必须估算结构的残余承载能力,这需要了解结构在高温作用后的性能,对相同配合比的混凝土试件在温度作用后的力学性能进行了初步的试验研究,包括抗压强度和横纵向应变,并分析了其变化规律,为高温后混凝土的温度时效研究提供了参考。

Abstract: When it comes to repairing damaged structure, it requires estimating the capability of concrete after being exposed to fire.The structure will keep integrity because of good fire resisting capability. The preliminary research on the mechanical properties of the same optimum mix concrete after temperature was conducted, including compressive strength, transverse strain and longitudinal strain, and its regularity was also analyzed.The reference for the investigation on temperature aging of concrete after high temperature is proposed.

Key words: concrete, aging, strength, mechanical property
