纤维种类对全轻混凝土抗冲击性能的影响

摘要

为进一步提升全轻混凝土材料的抗压强度,通过对其掺入乱向分布的纤维来进行性能改善.对全轻纤维混凝土的动态力学性能进行研究,有助于进一步了解纤维种类对全轻混凝土的改善效果.本文针对LC30全轻混凝土,单一或混合掺入聚丙烯纤维、钢纤维和碳纳米管纤维进行SHPB试验,探讨不同纤维种类对全轻混凝土抗冲击性能的影响.%In order to improve the compressive strength of all light concrete materials,the dynamic mechanical properties of all light fiber reinforced concrete can be improved by the improvement of the properties of the fi-bers mixed with the distributed distribution.In this paper,the effects of different fiber types on the impact re-sistance of LC30 concrete are studied by SHPB experiments of single or mixed polypropylene fiber,steel fiber and carbon nanotube fiber.
