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.
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.
