本文综述了应变硬化纤维增强水泥基复合材料的各种耐久性能。已发表的研究结果表明，由于与普通混凝土和普通纤维混凝土相比，其裂缝宽度较小，SHFRCC显著抵抗侵蚀性物质向混凝土中的迁移，并提高了钢筋混凝土（RC）的耐久性。由于应变硬化和多重开裂特性，SHFRCC满足不同设计规范提出的钢筋混凝土结构耐久性的严格裂缝宽度限制。基于审查的耐久性性能，它认为，SHFRCC材料可以使用在选定的位置的钢筋混凝土结构构件，以提高其整体耐久性能。(c)2007爱思唯尔有限公司保留所有权利。
This paper reviews and presents various durability properties of strain hardening fibre reinforced cementitious composites (SHFRCC). Published research results show that, due to its tight crack width properties compared to ordinary concrete and ordinary fibre reinforced concrete, SHFRCC significantly resists the migration of aggressive substances in to the concrete and improves the durability of reinforced concrete (RC). It is also reported that, due to the strain hardening and multiple cracking behaviours, SHFRCC meets the tight crack width limits for durability of RC structures proposed by different design codes. Based on the reviewed durability properties it is argued that SHFRCC materials can be used in selected locations of RC structural members to improve their overall durability performances.
