In order to study the impacts of aggregate size and fiber length on the mechanical properties of basalt fiber concrete, three aggregate sizes and basalt fiber lengths have been taken into account, and 108 concrete test blocks (including 72 cubic test blocks and 36 prism test blocks) have been designed and made. Furthermore, axial compression test, splitting tensile test as well as bending test have been carried out to analyze each parameter influence on compression strength, splitting tensile strength and bending strength. On the basis of random fiber script, ABAQUS finite element modeling analysis is carried out, and the corresponding strength calculation has been proposed. The results show that with the increase of aggregate size, the mechanical properties of matrix concrete are improved. While with the adding of basalt fibers, the concrete mechanical properties rise higher than aggregate size increase. The concrete mechanical properties present good performance when 30mm aggregate size mixes with 18 mm and 24 mm basalt fibers. The result of designed random fiber script in ABAQUS finite element modeling matches with the experiment well, and the calculation method considering two-parameter influence of aggregate size and basalt fiber length has good applicability.

为研究骨料粒径及纤维长度对玄武岩纤维混凝土力学性能的影响,考虑了三种骨料粒径和三种玄武岩纤维长度,设计并制作了108个混凝土试件(立方体试件72个,棱柱体试件36个),并对其进行了轴压试验、劈裂抗拉试验和抗折试验,分析了各参数对抗压强度、劈裂抗拉强度及抗折强度的影响规律,使用随机纤维脚本进行了ABAQUS有限元建模分析,并提出了相应强度计算方法。结果表明,随着骨料粒径的增长,基体混凝土的力学性能有所提升。而掺入玄武岩纤维后,混凝土的力学性能增大幅度较骨料粒径提升大。30 mm骨料粒径的混凝土在掺入18、24 mm玄武岩纤维时的力学性能相对较好。所编写的随机纤维脚本在ABAQUS有限元建模结果与试验结果吻合较好,考虑骨料粒径和玄武岩纤维长度的双参数影响的计算方法具有较好的适用性。

为研究骨料粒径及纤维长度对玄武岩纤维混凝土力学性能的影响,考虑了三种骨料粒径和三种玄武岩纤维长度,设计并制作了108个混凝土试件(立方体试件72个,棱柱体试件36个),并对其进行了轴压试验、劈裂抗拉试验和抗折试验,分析了各参数对抗压强度、劈裂抗拉强度及抗折强度的影响规律,使用随机纤维脚本进行了ABAQUS有限元建模分析,并提出了相应强度计算方法。结果表明,随着骨料粒径的增长,基体混凝土的力学性能有所提升。而掺入玄武岩纤维后,混凝土的力学性能增大幅度较骨料粒径提升大。30 mm骨料粒径的混凝土在掺入18、24 mm玄武岩纤维时的力学性能相对较好。所编写的随机纤维脚本在ABAQUS有限元建模结果与试验结果吻合较好,考虑骨料粒径和玄武岩纤维长度的双参数影响的计算方法具有较好的适用性。

In order to study the impacts of aggregate size and fiber length on the mechanical properties of basalt fiber concrete, three aggregate sizes and basalt fiber lengths have been taken into account, and 108 concrete test blocks (including 72 cubic test blocks and 36 prism test blocks) have been designed and made. Furthermore, axial compression test, splitting tensile test as well as bending test have been carried out to analyze each parameter influence on compression strength, splitting tensile strength and bending strength. On the basis of random fiber script, ABAQUS finite element modeling analysis is carried out, and the corresponding strength calculation has been proposed. The results show that with the increase of aggregate size, the mechanical properties of matrix concrete are improved. While with the adding of basalt fibers, the concrete mechanical properties rise higher than aggregate size increase. The concrete mechanical properties present good performance when 30mm aggregate size mixes with 18 mm and 24 mm basalt fibers. The result of designed random fiber script in ABAQUS finite element modeling matches with the experiment well, and the calculation method considering two-parameter influence of aggregate size and basalt fiber length has good applicability.
