摘要:

为探索植物纤维在3D打印水泥基材料领域中的应用,本研究以稻草纤维为外掺纤维,探讨了沸煮处理和高锰酸钾溶液处理对稻草纤维的改性效果,以及两种改性方法对3D打印稻草纤维水泥基复合材料性能的影响。结果表明,沸煮处理后稻草纤维表面变得干净且粗糙,但吸水率增加;高锰酸钾溶液处理后稻草纤维吸水率降低,同时稻草纤维表面粗糙度和结晶度增加。两种改性方法均显著提升了3D打印稻草纤维水泥基复合材料的力学性能、层间结合强度、条间结合强度,其中高锰酸钾改性效果更优。本研究为3D打印稻草纤维水泥基材料的设计和性能优化提供了新思路,扩大了稻草纤维在建筑领域的应用范围。

Abstract:

To explore the application of plant fibers in 3D printing cement-based materials, this study used rice straw fiber as an additive and investigated the modification effects of boiling treatment and potassium permanganate solution treatment on rice straw fiber, as well as their impact on the performance of 3D printing rice straw fiber cement-based composite. The results show that boiling treatment makes fiber surface clean and rough but increases their water absorption.Potassium permanganate solution treatment reduces water absorption while increasing surface roughness and crystallinity. Both modification methods significantly improve the mechanical properties, the interlayer bonding strength and interstrip bonding strength of 3D printing rice straw fiber cement-based composites, with the potassium permanganate modification superior. This work offers new idea for design and performance optimization of 3D printing rice straw fiber cement-based materials and broadens the application of rice straw fiber in the construction field.
