- 摘要:
- 为实现废弃碳纤维的资源化利用并提升混凝土力学性能，将废弃碳纤维与混凝土相结合，分析废弃碳纤维的纤维长度、体积掺量对不同水胶比混凝土的抗压强度、劈裂抗拉强度的影响；采用数字图像相关(Digital image correlation method，DIC)法对混凝土表面应变场的损伤演变过程进行监测，并结合正交实验法，对混凝土试件的抗压强度、劈裂抗拉强度试验结果进行极差分析，以确定废弃碳纤维混凝土的最佳配比；通过场发射扫描电镜对废弃碳纤维混凝土微观结构进行表征。结果表明：废弃碳纤维通过桥接裂缝和物理填充效应提升混凝土密实度，28 d 抗压强度和劈裂抗拉强度最高分别提高19.5%和44.7%；影响废弃碳纤维混凝土抗压强度及劈裂抗拉强度的因素，按影响程度由大到小依次为水胶比、体积掺量、纤维长度，最优配比为水胶比0.45、体积掺量0.2%与纤维长度6 mm；抗压条件下，试件表面存在明显的端部效应以及回弹效应，劈裂抗拉条件下，试件表面的最大横向应变集中于试件中部。该研究结果可为废弃碳纤维的绿色再生利用及高性能混凝土开发提供数据支撑。
