摘要
应变硬化水泥基复合材料(SHCC)是近20年发展起来的一种新型纤维增强水泥基复合材料,而混杂纤维SHCC通过调节不同纤维的比例关系,可便捷的获得满足工程需要的强度、变形、动态力学性能或经济性等要求。本文对混杂纤维SHCC的临界纤维掺量理论、准静态力学性能试验研究、动态力学性能试验研究进行了综述,最后就混杂纤维SHCC的研究存在的不足和发展方向进行了评述和展望。
Strain hardening cementitious composites（ SHCC） is a new type of fiber reinforced cementitious composites being developed in recent 20 years. By adjusting the proportion of different fibers,hybrid fiber SHCC can meet the needs of engineering strength,deformation,dynamic mechanical properties and economical demands conveniently. In this paper,the critical fiber theory of hybrid fiber SHCC,experimental study on quasi-static and dynamic mechanical properties are summarized. Finally,the deficiencies and development of the study in hybrid fibers SHCC are reviewed and prospected.
