分析了混杂纤维混凝土的纤维混杂类型、混杂效应以及工程应用情况,从强度和韧性、耐久性方面介绍了国内外二元及多元纤维混杂混凝土的研究进展。从规范指导、研究方法、增强机理和施工工艺等方面讨论了其研究和应用过程中存在的问题和不足,并提出了未来的发展趋势。
The fiber types, hybrid effect and the engineering applications of hybrid fiber reinforced concrete(HFRC) were analyzed. An overview of research progress in China and other countries regarding the performance of the HFRC of binary and multicomponent hybrid fibers were presented, such as strength, toughness and durability. Also the problems and insufficiencies of research and application such as the specification guide, research methods, reinforced principle and construction technology were dis- cussed, and then the future development trends were put forward.
