Abstract

Abstract

The cooperative work of high ductility cement-based composites and hyperelastic shape-memory alloy (SMA) can improve the energy-dissipation capacity and self-repair capacity of structure. The use of shape-memory alloy fiber can effectively solve some problems of shape-memory alloy bars or cables, so it has a broader application prospect. Several groups of test specimens were fabricated by embedding superelastic shape-memory alloy fibers with different diameters and end shapes into high-ductility cement-based materials with up to 3% tensile strain, some of which had different embedded depths. The pull-out tests of specimens were conducted by displacement-controlled loading, the stress-strain curves of pull-out for specimens were obtained, and the effects of various factors on the bonding properties between shape-memory alloy fiber and high-ductility cement-based composites were analyzed. The results showed that the knotted end could greatly improve the bond strength of shape-memory alloy fibers in the high-ductility cement matrix and provide sufficient anchoring forces for shape-memory alloy fibers to exert its superelasticity. The maximum tensile stress of all types of knotted specimens was above 900 MPa, and the maximum could reach 1 142.52 MPa. Among them, the specimen with knotted SMAF with diameter of 1.2 mm and embedded depth of 40 mm had better mechanical properties and fiber utilization ratios.
