摘要


开发具有减少碳足迹的可持续、环保绝缘材料正引起越来越多的关注。传统绝缘材料的一种替代品是泡沫
地质聚合物。与泡沫混凝土类似,泡沫地质聚合物的力学性能也可以通过使用纤维加固来提高。本文概述了纤维增
强泡沫地质聚合物混凝土领域的最新研究成果,特别关注天然纤维增强。此外,报告了天然纤维和泡沫地质聚合物
的一些基本和背景信息。在大多数研究中,泡沫是通过用过氧化氢或铝粉进行化学发泡或通过包含发泡剂的机械发
泡来生产的。然而,以前的评论还没有充分解决通过复合泡沫制造泡沫地质聚合物的问题。最后,讨论了最近为减
少地质聚合物混凝土中的纤维降解所做的努力,以及天然纤维增强泡沫地质聚合物混凝土面临的挑战。
