Abstract

To optimize the fiber mix ratio and simplify the compressive constitutive model, thereby enhancing the practicality of Engineered Cementitious Composite (ECC) materials, this study conducts an analysis through uniaxial compression experiments. The experiments combine both macro and micro perspectives to observe the cross-section and analyze the effects of fiber length and replacement ratio on the compressive strength of ECC materials. The results indicate that the addition of POM fibers can improve the dispersion of PVA fibers, leading to enhanced compressive performance; the toughness index increases with the fiber length. When the replacement ratio is at 50%, the impact of fiber length on the material's toughness is minimal. Finally, based on the stress-strain curves obtained from the experiments, a recommended model for the compressive stress-strain curve is proposed.
