活性粉末混凝土抗冲击性能的研究及进展

Research and development of impact resistance of reactive powder concrete

活性粉末混凝土是近30年来发展起来的一种超高性能混凝土,因其具有超高强度、超高韧性以及优异的耐久性等优点,受到行业的广泛关注,并在重大工程中得到应用和推广。但在实际工程中,不可避免受到撞击、爆炸、地震等动态荷载的冲击作用,对军工领域来说,更加考验活性粉末混凝土的抗侵彻性能。首先简要分析活性粉末混凝土的工程应用现状,然后重点对国内外研究学者在活性粉末混凝土抗冲击性能的试验方法、试验结论和数值模拟的研究进行综合论述。

Reactive powder concrete is a kind of ultra-high performance concrete developed in the past 30 years.Because of its advantages of ultra-high strength,ultra-high toughness and excellent durability,it has been widely concerned by the industry,and has been applied and promoted in major projects.However,in practical engineering,it is inevitable to be impacted by dynamic loads such as impact,explosion and earthquake.For the military industry,the anti-penetration performance of reactive powder concrete is even more tested.First of all,the current situation of engineering application of reactive powder concrete is briefly analyzed,and then the research methods,test conclusions and numerical simulation of impact resistance of reactive powder concrete by domestic and foreign researchers are comprehensively discussed.
