Abstract (2. Language): 
In this study, the effect of using different length of fiber (16 mm and 30 mm) and different ratio of water/cement (0.21 and 0.31) on compressive strength of ultra-high strength fiber reinforced concrete (UHSFRC) was examined. The UHSFRC samples were subject to compressive strength experiment on the 7th, 14th and 28th days. The compressive strength values for different fiber lengths and different water/cement ratios were evaluated. The results of study was shown, the results for samples prepared using steel fibers with length of 16 mm and 0.21 water/cement ratio was obtained better results than samples prepared using steel fibers with length of 30 mm and 0.31 water/cement ratio.

Abstract (Original Language): 
Bu çalışmada, farklı lif boylarının (16 mm ve 30 mm) ve farklı su/çimento oranlarının (0.21 ve 0.31) ultra yüksek dayanımlı fiber katkılı betonların (UYDFKB) basınç dayanımlarına olan etkileri incelenmiştir. Basınç dayanımı testleri numunelerin 7., 14. ve 28. yaşlarında yapılarak, değerler farklı lif boyları ve farklı su/çimento oranları için değerlendirilmiştir. Su/çimento oranı arttıkça basınç dayanımlarının azaldığı, lif boylarındaki artışın basınç dayanımında önemli olmayacak miktarda düşürdüğü gözlenmiştir. Çalışma sonucunda, 16 mm uzunluğunda çelik lifli ve 0.21 su çimento oranına sahip karışımın, 30 mm uzunluğunda çelik lifli ve 0.31 su/çimento oranlı karışımla üretilen numunelerden daha iyi sonuçlar elde edilmiştir.
