摘要

根据可持续发展的原则，应该使用环境友好、低排放和能源密集型的材料和技术，以及废物管理。混凝土
的生产需要消耗大量的能源和产生大量的二氧化碳；因此，有必要寻找新的解决方案，用其他材料，最好是回收材
料来代替组件。一个积极的方法是使用玻璃废料。为了确定大量玻璃渣含量对混凝土性能的影响，玻璃粉被用作填
料和 100%的玻璃骨料。水泥-玻璃复合材料的抗拉强度很低，而且是脆性破坏。为了提高抗拉强度，作者研究了添
加聚丙烯纤维对复合材料力学性能的影响。加入 300、600、900、1200和 1500克 /立方米的纤维，分别相当于水泥质
量的 0.0625%、0.1250%、0.1875%、0.2500%和 0.3125%，与基础样品相比，抗弯强度分别提高了 4.1%、8.2%、14.3%、
20.4%和 26.5%，而劈裂强度的提高分别为 35%、45%、115%、135%和 185%。此外，随着纤维的加入，与参考试样相比，
坍落度分别减少了 25.9%、39.7%、48.3%、56.9%和 65.5%。
