Study on the Mechanical Properties of Stone Powder-Fiber Seawater-Sea Sand Concrete

摘要: 为探究石粉、玄武岩纤维对海水海砂力学性能影响，从立方体抗压强度、劈裂抗拉强度和轴心抗压强度三个方面进行试验。研究结果表明，SSC-D₀B₂组较基准组立方体抗压强度提升约12.8%；SSC-D₁B₃组劈裂抗拉强较基准组提高约71.2%；SSC-D₁B₂组轴心抗压强度较基准组提高约23.5%。说明石粉、玄武岩纤维对海水海砂混凝土力学性能有显著提升效果。

Abstract: To investigate the effects of stone powder and basalt fiber on the mechanical properties of concrete made with seawater and sea sand, experiments were conducted in three aspects: cube compressive strength, splitting tensile strength, and axial compressive strength. The research results indicate that the cube compressive strength of the SSC-D₀B₂ group increased by about 12.8% compared to the reference group; The SSC-D₁B₃ group’s splitting tensile strength increased by approximately 71.2% compared to the reference group. The axial compressive strength of the SSC-D₁B₂ group increased by about 23.5% compared to the reference group. It indicates that mica powder and basalt fiber have a significant enhancing effect on the mechanical properties of seawater–sea sand concrete.
