摘要
超高性能混凝土(UHPC)是一种新型的水泥基材料,具有良好的裂缝自愈合潜力。对UHPC裂缝自愈合的研究进展进行了综述,归纳了UHPC基本特性及裂缝自愈合机理,讨论了裂缝自愈合行为对UHPC性能的影响,分析了最新的裂缝自愈合表征技术及自愈合理论模型,总结了目前UHPC裂缝自愈合研究中存在的关键问题,并提出了发展展望。
Ultra-high performance concrete(UHPC)is a type of cement-based material with good cracks self-healing potential.This paper reviewed the recent research progress on the cracks self-healing of UHPC.The basic characteristics of UHPC and the mechanism of cracks self-healing were summarized.The effect of cracks self-healing behavior on the performance of UHPC was discussed.The state-of-the-art characterization techniques and the theoretical models of cracks self-healing were analyzed.The major problems existing in the current research on the cracks self-healing of UHPC were summarized,and the development prospects were put forward.
