结合可再生的高密度聚乙烯（HDPE） 混凝土的工程性能：系统评价
摘要
和经济可持续性的解决方案之一。本文全面回顾了以骨料或纤维或胶凝材料形式掺入混凝土中的再生高密度聚乙
烯（HDPE）工程性能的文献。HDPE细骨料混凝土在HDPE-10下观察到，最佳 28天抗压和抗弯强度，在HDPE-5
下观察到劈裂抗拉强度，而对于HDPE粗骨料混凝土，在HDPE掺入量的 10%至 15%范围内和在HDPE-15。同样，
HDPE纤维增强混凝土的 28天弯曲和劈裂抗拉强度分别提高到HDPE-3时 4.9MPa和HDPE-3.5时 4.4MPa的最佳值，
并且高于标准 /普通混凝土基体（HDPE-0）在所有HDPE包含水平。HDPE的疏水性、光滑的表面纹理和非反应性
导致混凝土基体与HDPE之间的结合较弱，从而随着HDPE的增加而降低HDPE混凝土的力学和耐久性性能。总体
而言，这是第一次介绍和分析再生HDPE作为可持续建筑材料的机械和耐久性性能的现状，因此，推动了HDPE混
凝土更好性能和成功应用的研究。
