摘要/Abstract

摘要： 为研究极端环境下高性能水泥基材料的性能,本研究利用分离式霍普金森压杆(SHPB)装置,系统研究了高强高延性水泥基复合材料(HS-ECC)在循环冲击荷载下的动态压缩性能,重点分析了不同冲击速度和钢纤维体积掺量对动态压缩性能的影响。结果表明:钢纤维掺量为0.6%(体积分数)的HS-ECC试件,在承受6次冲击速度5 m/s的循环冲击后发生破坏,且随着冲击次数增加,HS-ECC试件的应变率增加;动态压缩强度、应变率和冲击韧度均随冲击速度显著增长;钢纤维掺入显著提高了HS-ECC的冲击极限承载力和韧性,当钢纤维掺量由0%增至0.6%时,试件的动态压缩强度提升23.4%,试件动态冲击韧度提升达52.9%,充分证明钢纤维掺量对HS-ECC动态力学性能的正向调控作用。HS-ECC在防爆抗冲击领域如军事防护或核电站防护墙等极端环境具有广阔的应用前景。

Abstract: In order to study the performance of high-performance cementitious materials under extreme environments, this study systematically investigated the dynamic compression performance of high strength and high ductility engineered cementitious composites (HS-ECC) under cyclic impact loading using a split Hopkinson pressure bar (SHPB) device, focusing on the effects of different impact velocities and steel fiber volume doping on the dynamic compression performance. The results show that, HS-ECC specimens with steel fibers doping of 0.6%(volume fraction) are damaged after six cyclic impacts with an impact velocity of 5 m/s, and the strain rate of HS-ECC specimens increases with the increase of the number of impacts. Dynamic compressive strength, strain rate and impact toughness all increase significantly with impact velocity. Steel fiber doping significantly improves the impact ultimate load carrying capacity and the toughness of HS-ECC, when the content of steel fiber increases from 0% to 0.6%, the dynamic compressive strength of the specimen increases by 23.4%, and the dynamic impact toughness of the specimen increases by 52.9%, which fully proves that the content of steel fiber has a positive regulatory effect on the dynamic mechanical properties of HS-ECC. HS-ECC has a wide range of application prospects in the field of anti-explosive and anti-impact areas, such as the extreme environment of military protection or the protection wall of the nuclear power plant.
