It is expected that trade-offs between composite tensile strength and tensile ductility are
needed. For example, higher composite strength may be reached by engineering the mortar matrix to have a higher toughness and/or smaller initial flaws, at the expense of ductility. The optimal mix of strength and ductility depends on the particular structural application. For the link-slab, it is clear that tensile ductility is more important to sustain the large imposed deformation, and is given priority over strength. The mix composition of the ECC described in Table 1 provides all the necessary properties required of the link-slab application [11]. In particular, the tensile strength of 3.5 MPa, a yield strain εty of 0.02% .(corresponding to a Young’s modulus E of 17.5 GPa), with a tensile ductility εtu of 2% (minimum), and a steady state crack width wss
Of 60lm, meet the target composite property requirements specified above. A typical stress–strain curve of this material is given in Fig. 2.These material properties have been obtained from a uniaxial tension test [13]. The 28-day compressive strength and strain capacity εc of this mix is about 75 MPa and 0.43%.

据预计,需要在复合材料的抗拉强度和拉伸延展性之间进行权衡.例如,较高的复合材料强度可通过工程设计砂浆基体具有较高的韧性和/或较小的初始缺陷来达到,但代价是延性要减小.强度和延展性的最佳组合取决于具体的结构应用.对于链接桥板来说,很显然,拉伸延展性对于承受施加的大的变形来说更加重要,并且相对于强度给予更大的优先权.在表1中记载的ECC混合组成提供了所有的链接桥板应用[11]所需的必要性能.特别是,3.5MPa的抗拉强度,0.02％的屈服应变εty（相应于17.5 GPA的杨氏模量E）,以及2％（最小）的拉伸延展性εtu,和60lm的稳态裂缝宽度,满足上述规定的复合材料性能的目标要求.这种材料典型的应力 - 应变曲线在图2中给出.这些材料性质已经从单轴拉伸试验[13]中获得.这种混合组合的 28天抗压强度和应变能力εC约为75MPa和0.43％.
