| 摘 要： | 搜集了国内外高性能砼材料试验结果,通过对试验资料分析得出在砼中掺加某些化学物质可以在高性能砼中形成许多微裂缝,能够防止其构件在火灾中发生爆裂反应,进而使其抗火性能与普通砼结构相同。

| Abstract: | Based on a lot of test results for high performance concrete, this paper shows that the splitting of high performance concrete structures on fire can be prevented on the condition of mixing a certain kind of chemical substance into concrete, which may produce micro cracks in concrete . So, high performance concrete structure will get as well as general concrete ones on fire. |

| Keywords: | high performance splittng micro crack |
