聚丙烯纤维对高性能混凝土高温性能的影响

Investigation of Influence of PP Fiber on Performances of HPC under High Temperature

摘要:

研究了聚丙烯纤维对高温下高性能混凝土性能的影响．结果表明，聚丙烯纤维可在较小程度上提高高温下的混凝土抗折强度，降低高温下的混凝土动弹性模量损失率，而对改善混凝土的抗爆裂性能尤其有效．

Abstract:

The influence of PP fiber on concrete properties under high temperature was studied. Test results show that PP fiber can improve flexural strength of concrete to a little extent, reduce loss percentage of concrete dynamic elastic modulus and has significant improvement on anti-spalling of concrete.
