Mechanical properties and fractional-order creep constitutive model of steel fiber-reinforced coal gangue-based CLSM
To promote the high-value utilization of coal gangue, this study developed a steel fiber-reinforced coal gangue-based controlled low-strength material (CLSM) as a green backfill material. The effects of fiber content (0%–2.0%) on its mechanical properties were investigated, and a fractional-order creep constitutive mod...
