| Abstract: | The factors which affect the strength of concrete during the heat cyle,including the constitution of material and environmental factors are analysed and summarized in this paper.Change of microstructure with temperature and destructive mechanism are analysed too.The nature behavior of concrete at temperatures and after cooling are explained.Conclusions of this paper provied a foundation for fire resistance design of reinforced concrete structure and retrofit after fire. |
