摘要

使用新型原材料开发建筑材料是目前社会和行业的需求。其目的是为了降低生产成本，改善性能，并获得
越来越多的可持续发展过程和产品。在这方面，这项工作旨在评估新型加固材料对水泥基板材的物理机械和热性能
的影响。作者对用松木、咖啡壳废料、稻壳和聚对苯二甲酸乙二醇酯（PET）加固的水泥基板材进行了评估。这些
板材是以 1.30g.cm-3的名义密度；1：2.5的加固材料：水泥比例；1：1.5的水：水泥比例；0.25的水泥水化率，使用
波特兰ARIV水泥和 3%的氯化钙（CaCl2）作为添加剂。在加速老化之前和之后，作者对板材的物理、机械和热性
能进行了评估。PET瓶废料显示出用于水泥基板材生产的巨大潜力，获得了最好的物理和机械结果，并显示出优于
松木板材的性能。用咖啡壳和稻壳废料加固的水泥基板材获得了较低的物理机械性能，呈现出使用上的局限性，然
而，其热导率值最低。
