High-ductility self-recovery cement-based material and preparation method thereof
The invention discloses a high-ductility self-recovery cement-based material and a preparation method thereof, the cement-based material comprises cement mortar, SMA fibers and carbon black, and the mass ratio of SMA fibers to carbon black is 32: 5-96: 10. The preparation method of the high-ductility self-recovery cement-based material comprises the following steps: mixing the cement mortar with the carbon black, and adding the SMA fibers to obtain the high-ductility self-recovery cement-based material. The cement-based material disclosed by the invention has high ductility, can sensitively monitor the cracking condition, and can be self-recovered after cracking; the SMA fibers are uniformly dispersed by changing the feeding sequence, so that the prepared cement-based material has the characteristics of high ductility and multi-crack development of a common fiber cement-based material, and also has the capability of recovering part of cracks.
本发明公开了一种高延性自恢复水泥基材料及其制备方法，该水泥基材料包括水泥砂浆，SMA纤维和炭黑，所述SMA纤维与炭黑的质量比为32:5～96:10。上述高延性自恢复水泥基材料的制备方法，先将水泥砂浆中和炭黑混合，后加入SMA纤维，得到所述高延性自恢复水泥基材料。本发明的水泥基材料具有高延性、能够灵敏监控开裂情况，且开裂后能够自恢复；通过改变加料顺序使得SMA纤维均匀分散，制得的水泥基材料既具有普通纤维水泥基材料的高延性和多裂缝开展的特性，又具有可以恢复部分裂缝的能力。
