砂浆是常见的水泥基体,为了对比研究不同玄武岩纤维制品对水泥基复合材料力学性能的增强效果,将短切玄武岩纤维及玄武岩纤维土工格栅分别以掺入和铺层的方式加入到水泥基体中,掺量为0.2%,铺层数为3层,并进行了抗压和抗折力学性能实验。结果表明,短切玄武岩纤维和玄武岩纤维土工格栅均能够对砂浆起到增强效果,且玄武岩纤维土工格栅对砂浆增强效果更佳,抗压强度和抗折强度最高分别提高45.93%和51.03%,说明具有交织结构的玄武岩纤维格栅对砂浆力学性能具有积极作用。
Mortar is a common cement matrix.In order to compare the effects of different basalt fiber products on the mechanical properties of cement-based composites,the chopped basalt fiber and basalt fiber grilles were added to the cement matrix by incorporation and layering.The amount and layup were 0.2% and 3 layers,respectively,and the compressive and flexural mechanical properties were tested.The results showed that the chopped basalt fiber and basalt fiber grilles could enhance the mortar,and the basalt fiber grilles had better reinforcement effect,and the compressive strength and flexural strength could be increased by 51.59% and 51.03%.It shown that the basalt fiber grille with interwoven structure can play a positive role in the mechanical properties of the mortar.
