摘    要:对常温20℃及200~600℃高温后高性能混凝土进行单轴抗压强度力学性能试验,测其抗压强度,并建立了高温后高性能混凝土抗压强度随温度变化的公式。试验结果表明:伴随温度升高,高温200~300℃后高性能混凝土抗压强度有所升高,400℃左右是抗压强度明显变化的临界温度。

关 键 词:高性能混凝土  高温  力学性能

Abstract:It is attempted to generate information on the compressive strength behavior of plain high-performance concrete(HPC) after 20℃(normal temperature),200℃,300℃,400℃,500℃and 600℃ levels of high temperatures.The compressive strengths were measured.The formula of plain HPC with the temperature parameters is proposed.The experimental results show that the compressive strength of plain HPC after 200℃~300℃ is increased with the increase of temperature and its critical temperature is around 400℃.
Keywords:high-performance concrete(HPC)  high temperatures  mechanical properties
