对近年来高强混凝土高温性能的研究成果进行了综述与分析,包括热工性、高温下和高温后力学性能以及高强高性能混凝土的爆裂性能。其中,高强混凝土热工性能方面的研究成果较少且研究结果离散性较大;高强混凝土力学性能方面的研究主要集中于抗压强度、抗拉强度、变形性能、弹性模量、泊松比、应力 应变关系等,而对高强混凝土结构、构件高温力学性能和温度场分析方面的研究较少;高强高性能混凝土爆裂方面的研究多集中于爆裂规律和爆裂抑制措施,对爆裂机理和微观结构的研究较少。本文分别从3个方面指出了高强混凝土高温性能研究中存在的问题和今后的研究方向,为深入研究高强混凝土的高温性能提供参考。 |

The recent researches on high temperature properties of high strength concrete are summarized and analyzed, including the thermal performance, mechanical properties and the spalling behavior. There are few studies on the thermal performance of high strength concrete and the results of large discrete. Research on the mechanical properties of high strength concrete has been focused on the compressive properties, tension properties, deformation properties, elastic modulus, Poisson’s ratio, stress strain relationship, etc., but few studies have been performed on the mechanical properties and temperature field of high strength concrete structures and members. A lot of researches on the spalling law and spalling inhibition of high strength concrete have been carried out, but the studies on the spalling mechanism and microstructure are not enough. In this paper, the existing problems and future research directions of the high temperature properties of high strength concrete are pointed out from three aspects, which provide a reference for further study on high temperature properties of high strength concrete. |
