工程水泥基复合材料(ECC)的高拉伸应变能力对于水泥基材料来说是非常特殊的。本文对影响ECC拉伸性能的因素，特别是纤维性能、试件尺寸和几何尺寸以及应变速率进行了全面综述。ECC的耐久性能，包括长期拉伸性能、高温冲击下的力学行为以及循环和疲劳载荷下的力学行为，也受到了特别的关注。结果表明：(1)纤维性能对ECC的拉伸性能有决定性影响；(2)拉伸试验中存在尺寸和几何效应，有待进一步研究；(3)高速加载导致ECC拉伸性能发生明显变化；(4)为了更好地应用ECC材料，应进一步研究其拉伸性能的耐久性。
The high tensile strain capacity of engineered cementitious composites (ECC) is exceptional for cementitious material. In the present paper, a comprehensive review is conducted to summarize the fundamental information of factors that influence the tensile properties of ECC, specifically the fiber properties, specimen size and geometry, and strain rate. The extended durability of ECC, including the long-term tensile properties, the mechanical behaviors under the high temperature impact and the cyclic and fatigue loading, is also paid special attention. It is concluded that (1) fiber properties have a decisive effect on the tensile performance of ECC; (2) size and geometry effect exists in tensile test and needs further study; (3) high rate loading leads to a noticeable changes in the tensile properties of ECC; and (4) durability of tensile properties should be further investigated for the better application of ECC material.
