Abstract:

 In this study, mechanical behavior and fracture energy values of SIFCON containing normal strength 3D and high strength 5D steel fibers and polyolefin-based synthetic fiber after 90C steam curing and 150C oven curing were investigated. In addition, the effect of thermal curing processes on the permeability properties of SIFCON was determined by capillary water absorption tests. Steel fibers were used at 4 and 8 by volume. On the other hand, polyolefin fiber was used only 4. It was prepared in reference samples that did not use fiber for comparison purposes. The highest fracture energy values were obtained in the samples containing 5D type high strength steel fiber as 19,7 kNm. Among the fibrous mixtures, the lowest fracture energy was found to be 5,7 kNm in the samples containing polyolefin fibers. The capillary water absorption values of the oven-cured samples in permeability tests are higher than the steam-cured samples. As a result of the study, it was determined that the oven cure applied at higher temperature improved the mechanical properties and fracture energy values of SIFCON more than the steam cure. On the other hand, it was understood that the oven cure increased the capillary water absorption values of SIFCON and negatively affected the permeability compared to the steam cure.

 Bu çalışmada, normal mukavemetli 3D ve yüksek mukavemetli 5D çelik lifler ve poliolefin esaslı sentetik lif içeren SIFCONun 90C buhar kürü ve 150C etüv kürü sonrası mekanik davranışı ve özellikle de kırılma enerjisi değerleri incelenmiştir. Ayrıca ısıl kür işlemlerinin SIFCONun geçirimlilik özelliklerine etkisi kılcal su emme testleri ile belirlenmiştir. Çelik lifler hacimce 4 ve 8 oranında kullanılmıştır. Bununla birlikte, poliolefin lif sadece 4 oranında kullanılmıştır. Karşılaştırma amacıyla lif kullanılmayan referans numunelerde hazırlanmıştır. En yüksek kırılma enerjisi değerleri, 19,7 kNm olarak 5D tipi yüksek dayanımlı çelik lif içeren numunelerde elde edilmiştir. Lifli karışımlar arasında ise en düşük kırılma enerjisi, poliolefin lifleri içeren numunelerde 5,7 kNm olarak belirlenmiştir. Geçirimlilik testlerinde ise etüv kürü uygulanan numunelerin kılcal su emme değerleri buhar kürü uygulanan numunelere göre daha yüksektir. Çalışma sonucunda, daha yüksek sıcaklıkta uygulanan etüv kürünün, SIFCONun mekanik özelliklerini ve kırılma enerjisi değerlerini buhar kürüne göre daha fazla geliştirdiği tespit edilmiştir. Buna karşın, etüv kürünün SIFCONun kılcal su emme değerlerini arttırdığı ve buhar kürüne kıyasla geçirimliliği olumsuz olarak etkilediği belirlenmiştir.
