| 摘 要： | 高性能混凝土与传统混凝土相比,结构密实,脆性更大,渗透性低,尤其是在火灾高温状态下发生爆裂现象因而造成其抗火性差。为此,提出在高性能混凝土中混掺聚丙烯纤维和钢纤维、外加减水剂及骨料两种技术措施,以提高高性能混凝土的耐火性能。

| Abstract: | High performance concrete is more solid in structure,more brittle in performance and lower permeability.It is easy to crack and split in high temperature caused by a fire.This paper suggests the way to improve the fire resistant performance of high performance concrete by adding polypropylene fiber and steel fiber in addition to water-reducers and aggregate. |

| Keywords: | high performance concrete fire resistance performance crack and split technical measures |
