Abstract:

To enhance the toughness of ferroaluminate cement-based materials, this research presented the design of a multi-scale hybrid fiber composite system through the incorporation of polyoxymethylene (POM) fiber and polypropylene (PP) fiber. The impact of this system on the fundamental mechanical properties of ferroaluminate cement mortar, including fluidity, flexural strength, compressive strength, ultimate tensile strength, and bending strength was examined. Furthermore, scanning electron microscopy was employed to examine its microstructure. The results indicate that the impact of hybrid fibers on the fluidity of ferroaluminate cement is less significant than that of single type fiber. POM fiber can significantly enhance the flexural strength of cement when two types of fiber are mixed. Both single and composite fiber incorporations can markedly enhance the deflection capacity of ferroaluminate cement-based materials. When the volume fractions of PP fiber and POM fiber are both 0.3%(mass fraction), the hybrid fiber system demonstrates a remarkable “positive hybrid effect”, resulting in the maximum enhancement of equivalent bending strength. Microscopic examination reveals that POM fiber and PP fiber can synergistically operate across various dimensional scales to collectively impede fracture propagation, thereby enhancing the toughness of ferroaluminate cement-based materials.
