摘要
就国内外的研究结果,总结普通高强混凝土、钢纤维高强混凝土和聚丙烯高强混凝土高温后的强度和耐久性、渗透性能恶化的规律。综合阐述高强混凝土的耐火性能,并深入探讨高强混凝土高温爆裂机理,影响爆裂的主要因素及防治方法,并对高强混凝土耐火性能的研究方向提出建议。
According to research results in China and other countries, the laws of strength, durability and permeability deterioration after high temperature of normal high strength concrete, steel and polypropylene fiber reinforced high strength concrete were concluded. The fire resistance of high strength concrete was generally described. The mechanism of high-strength con- crete high temperature burst, main factors impacting burst and control methods were discussed. The research topic of high strength concrete fire resistance was suggested.
