Implication

Experimental study demonstrates steel fibers enhance abrasion resistance in fly ash concrete while flexural strength strongly correlates with wear, suggesting flexural capacity drives durability.

Key Points

To evaluate how fly ash, steel fibers, and polypropylene fibers influence the abrasion resistance of concrete and to determine its relationship with compressive and flexural strength.
Prepared 28 concrete mixtures with a constant 0.35 water-binder ratio, testing fly ash cement replacement (0–45%), steel fibers (0.25–1.5% by volume), and polypropylene fibers (0.05–0.2% by volume).
Tested 28-day Bohme surface abrasion alongside compressive and flexural tensile strength.
Assessed relationships between abrasion loss and mechanical strength properties using linear regression R² values on a logarithmic scale.
Fly ash replacement of cement reduced concrete abrasion resistance, whereas steel fiber inclusion improved abrasion resistance across mixtures.
Polypropylene fiber reinforcement failed to improve abrasion resistance in concrete with or without fly ash.
Abrasion resistance correlated more strongly with flexural tensile strength than with compressive strength across concrete mixtures containing fly ash and fibers.
