摘要

摘要: 不锈钢绞线工程水泥基新型复合材料是将不锈钢绞线放入工程水泥基复合材料（ECC）而形成的一种新型高性能复合材料。对6组不锈钢绞线ECC复合材料进行张拉试验，结果表明：随不锈钢绞线配筋率和ECC抗拉强度的增大，不锈钢绞线ECC复合材料受拉的开裂应力、应变以及极限应力和应变均增大，极限应力、应变增大幅度明显大于开裂应力和应变；试验得出的新型复合材料的应力-应变关系曲线，可为该复合材料进一步应用提供参考。

Abstract: A new high performance composite, namely, stainless steel strand reinforced Engineered Cementitious Composite (ECC), which is formed by inserting stainless steel strand into ECC. At present, the research on the stainless steel strand reinforced ECC composite material is still in the initial stage. In this paper, six groups of stainless steel strand reinforced ECC tension specimens were designed and fabricated, and the tension tests was carried out considering the test variables such as ECC tensile strength, reinforcement ratio of stainless steel strands in tension direction and so on. The results showed that as the reinforcement ratio or ECC tensile strength increased, the cracking stress, cracking strain, ultimate stress and ultimate strain of the stainless steel strand reinforced ECC were enhanced, and the increase of ultimate stress and ultimate strain was significantly greater than that of cracking stress and cracking strain. According to the test results, the stress-strain curve of this new composite material of this new composite material was obtained. The research presented in the paper could provide theoretical support for further application of this composite material.
