Abstract Fibre reinforced concrete (FRC) has gained increasing interest in recent years due to its superior mechanical properties compared to normal concrete. To apply FRC in civilian and strategically important buildings and other infrastructures, fire resistance is an inevitable matter of concern. According to the existing test results, different fibre types, fibre dosages and cementitious matrix designs would affect the fire resistance of FRC. This paper presents a comprehensive review of the recent research works on the fire resistance of FRC. In particular, the temperature-dependent mechanical properties of steel fibre reinforced concrete, polypropylene fibre reinforced concrete and hybrid fibre reinforced concrete are discussed, including permeability, spalling, compressive strength, tensile strength, elastic modulus, toughness and mass loss. In addition, the currently available predicting equations for FRC residual properties are summarised and compared.

纤维增强混凝土高温力学性能综述

摘要 近年来，纤维增强混凝土 (FRC) 因其与普通混凝土相比具有优异的机械性能而受到越来越多的关注。将 FRC 应用于民用和具有重要战略意义的建筑物和其他基础设施，耐火性是一个不可避免的问题。根据现有的测试结果，不同的纤维类型、纤维用量和胶凝基体设计会影响 FRC 的耐火性。本文对近期关于 FRC 耐火性的研究工作进行了全面回顾。特别讨论了钢纤维混凝土、聚丙烯纤维混凝土和混合纤维混凝土的温度相关力学性能，包括渗透性、剥落、抗压强度、抗拉强度、弹性模量、韧性和质量损失。
