这项研究通过结合子废料纤维,飞灰和碳纳米管来增强混凝土,以提高结构性能. 最佳的混合物显著提高了压缩和屈曲强度,同时减少了水的吸收.
科学领域:
- 材料科学 材料科学 材料科学
- 土木工程 土木工程是指土木工程.
- 可持续建筑 可持续建筑
背景情况:
- 混凝土的收缩,低强度与重量比,以及易受裂纹的可能性是重大挑战.
- 使用废物作为沙子替代品为混凝土生产提供了经济和环境的好处.
研究的目的:
- 为了减轻收缩,增强混凝土的压缩和屈曲强度.
- 研究子废料切碎纤维 (wCF),废物飞灰 (wFA) 和碳纳米管粉 (CNT) 对混凝土性能的影响.
主要方法:
- 开发的混凝土混合物含有5重%的wCF,10重%的wFA,以及不同的CNT含量 (0,5,10,15重%).
- 通过X射线衍射,散密度,压缩强度,屈曲强度和吸水测试来评估混凝土的性能.
主要成果:
- X射线衍射证实了wCF,wFA,CNT和混凝土矩阵的组成.
- 在28天的固化后,最佳混合物 (5重%wCF,10重%wFA,15重%CNT) 显示出最大的压缩强度 (47±1.8MPa) 和屈曲强度 (4.9±0.19MPa).
- 优化的混凝土混合物表现出一个低的吸水率 (2.8 ± 0.05%).
结论:
- 联合使用wCF,wFA和CNT有效地提高了混凝土的机械性能,并减少了水的吸收.
- 这项研究表明,使用废物生产混凝土的可持续方法可以提高结构完整性.
