Abstract In the present study, various amounts of glass microfibres were introduced into a geopolymer for reinforcement purposes. The influence of these microfibres on the performance of the geopolymer composites was investigated. Results show that the appropriate addition of glass microfibres can improve the mechanical properties of geopolymer composites. In particular, the flexural strength, flexural modulus and impact strength increase at an optimum fibre content of 2 wt%. Further, adding glass microfibres to a plain geopolymer matrix has a significant effect on the pre-cracking behaviour. It substantially enhances the post-cracking response.

添加玻璃微纤维对粉煤灰基地质聚合物复合材料力学性能的影响

摘要 在本研究中，为了加固目的，将不同数量的玻璃微纤维引入地质聚合物中。研究了这些微纤维对地质聚合物复合材料性能的影响。结果表明，适当添加玻璃微纤维可以提高地质聚合物复合材料的力学性能。特别是，在 2wt% 的最佳纤维含量下，弯曲强度、弯曲模量和冲击强度增加。此外，在普通地质聚合物基体中加入玻璃微纤维对预开裂行为有显着影响。它大大增强了开裂后的响应。
