Highlights SMA-FRCC has demonstrated pre-stressing effects after a short period of heating. A short period of heat treatment successfully activated the shape memory effects. Heat treatment of SMA-FRCCs enhanced the Young’s modulus of the SMA-FRCCs.
Abstract We demonstrated the pre-stressing capability of short shape-memory-alloy (SMA) fiber-reinforced cementitious composites (SMA-FRCC) by performing direct tensile tests after heat treatment. Two types of SMA fibers were added by 1.5% volume content in a mortar matrix with 55MPa compressive strength. After 10min of heat treatment on the tensile specimens of SMA-FRCCs, the length of specimen was noticeably shortened due to shape-memory effects, which consequently generated pre-stressing effects. Furthermore, heat treatment noticeably increased the Young’s modulus of SMA-FRCCs in tension due to shape-memory effects.
