The durability and mechanical properties of High-Performance Fiber Reinforced Concrete, HPFRC, are experimentally investigated in this study after being exposed to four different media. Those media were air, water, sodium chloride, and magnesium sulfate with 7% concentration for both chloride and sulfate. Hooked-end galvanized steel fiber 50 mm length with three different fiber volume fractions, Vf, as follows 0.5%, 1% and 1.5% and polypropylene fiber with, Vf, 0.1%, 0.3%, and 0.5% were invoked in concrete containing macro silica fume, SF. Compressive, indirect tensile, and flexural tests were conducted on HPFRC specimens after exposing them to previous media after 28 and 180 days of exposure. The test results in the present work indicated that the HPFRC containing steel fiber is more durable than the other one containing polypropylene fiber, especially when exposed to sodium chloride and magnesium sulfate media. Moreover, the optimum values for compressive strength of HPFRC are obtained when Vf equals 1% for steel fiber and 0.3% for polypropylene fiber. On the other hand, the optimum values for indirect tensile and flexural strengths of HPFRC are obtained when Vf equals 1.5% for steel fiber and 0.5% for polypropylene fiber.

Bu çalışmada, Yüksek Performanslı Elyaf Takviyeli Beton (HPFRC) dört farklı ortama maruz bırakıldıktan sonra mekanik ve durabilite özellikleri deneysel olarak incelenmiştir. Bu ortamlar hava, su, her ikisi de %7 konsantrasyonda sodyum klorür ve magnezyum sülfattır. 50 mm uzunluğunda kanca uçlu galvanizli çelik lif %0.5, %1.0 ve %1.5 olmak üzere üç farklı hacim fraksiyonunda (Vf), makro silis dumanı (SF) içeren betonda ise polipropilen lif %0.1, % 0.3 ve %0.5 hacim fraksiyonlarında kullanılmıştır. HPFRC numuneleri önceki ortamlara 28 ve 180 maruz kaldıktan sonra, basınç dayanımı, dolaylı çekme ve eğilme deneyleri gerçekleştirilmiştir. Mevcut çalışmadaki deney sonuçları, çelik lif içeren HPFRC'nin, özellikle sodyum klorür ve magnezyum sülfat ortamına maruz kaldığında, polipropilen lif içeren diğerine göre durabilitesinin daha iyi olduğunu göstermiştir. Ayrıca, HPFRC'nin basınç dayanımı için optimum değerler, Vf, çelik fiber için %1.0 ve polipropilen fiber için %0.3'e eşit olduğunda elde edilmiştir. Bununla birlikte, HPFRC'nin dolaylı çekme ve eğilme dayanımları için optimum değerler, Vf, çelik elyaf için %1.5 ve polipropilen elyaf için %0.5'e eşit olduğunda elde edilmiştir.
