碱处理纤维增强界面相容性是地聚合物纤维复合材料的关键。然而，碱处理后的黑液污染和地聚合物与天然纤维之间的相容性差，极大地限制了天然纤维在GFC中的应用。本研究通过将CaCl 2溶液（1 mol/L）浸入碱处理红麻纤维和回收作为再生活化剂的黑液中，获得了改善GFCs相容性、弯曲强度（增加69.1%）、韧性（增加473%）和韧性破坏模式的GFCs。这一结果可作为低成本和生态友好型全球气候中心筹备工作的基础。
Interfacial compatibility enhanced by alkali-treated fiber is the key to the geopolymer-fiber composites (GFCs). However, applications of natural fibers in the GFCs are greatly limited by the black liquid pollution and weak compatibility between geopolymer and natural fibers after alkali-treatment. In this study, the improved compatibility, flexural strength (increased by 69.1%), toughness (increased by 473%), and ductile failure mode of the GFCs were obtained by CaCl2solution (1 mol/L) immerged into the alkali-treated kenaf fiber and black liquid recycled as a regenerated activator. This outcome could be served as a basis for the low-cost and eco-friendly preparations of the GFCs.
