long-term durability — chloride penetration, freeze-thaw resistance — and cyclic performance under seismic loading. It is concluded that the use of fibers and fly ash in combination causes a significant improvement in the mechanical behavior and durability properties of concrete. A 20% fly ash replacement level, along with hybrid fiber reinforcement, offers the best combination of strength, ductility, and sustainability. The results suggest that providing inexpensive, yet highly suitable concrete mixes for future construction projects can be achieved.
