“…It was also observed that UHPC mixtures incorporating long steel fibers exhibited enhanced performance under impact loading compared to that incorporating short fibers (Yu et al 2014). Aoude et al (2015) tested UHPC columns under simulated blast loading using a shock tube testing facility. It was observed that the concrete type, fiber type and dosage, longitudinal reinforcement ratio and spacing between transverse reinforcement were the important parameters that effect the failure pattern of UHPC columns subjected to blast loading (Aoude et al 2015).…”

In this study, an extensive literature review has been conducted on the material characterization of UHPC and its potential for large-scale field applicability. The successful production of ultra-high performance concrete (UHPC) depends on its material ingredients and mixture proportioning, which leads to denser and relatively more homogenous particle packing. A database was compiled from various research and field studies around the world on the mechanical and durability performance of UHPC. It is shown that UHPC provides a viable and long-term solution for improved sustainable construction owing to its ultrahigh strength properties, improved fatigue behavior and very low porosity, leading to excellent resistance against aggressive environments. The literature review revealed that the curing regimes and fiber dosage are the main factors that control the mechanical and durability properties of UHPC. Currently, the applications of UHPC in construction are very limited due to its higher initial cost, lack of contractor experience and the absence of widely accepted design provisions. However, sustained research progress in producing UHPC using locally available materials under normal curing conditions should reduce its material cost. Current challenges regarding the implementation of UHPC in full-scale structures are highlighted. This study strives to assist engineers, consultants, contractors and other construction industry stakeholders to better understand the unique characteristics and capabilities of UHPC, which should demystify this resilient and sustainable construction material.

An overall review of the structural behaviors of ultra-high-performance fiber-reinforced concrete (UHPFRC) elements subjected to various loading conditions needs to be conducted to prevent duplicate research and to promote its practical applications. Thus, in this study, the behavior of various UHPFRC structures under different loading conditions, such as flexure, shear, torsion, and high-rate loads (impacts and blasts), were synthetically reviewed. In addition, the bond performance between UHPFRC and reinforcements, which is fundamental information for the structural performance of reinforced concrete structures, was investigated. The most widely used international recommendations for structural design with UHPFRC throughout the world (AFGC-SETRA and JSCE) were specifically introduced in terms of material models and flexural and shear design. Lastly, examples of practical applications of UHPFRC for both architectural and civil structures were examined.

“…UYDFKB'ın basınç dayanımları 150-200 MPa değerleri arasında, çekme dayanımları ise 10 MPa'dan yüksektir ve geleneksel beton ile karşılaştırıldığında düşük porozite, düşük geçirgenlik ve üstün dayanıklılık özelliklerine sahip olduğu gözlenmiştir [8,9]. Tayeh'e [10] göre günümüzde pek çok akademisyen, bilim adamı ve mühendisler; UYDFKB'ın geleneksel betona göre, betondan istenilen performansa daha iyi cevap verdiğini kabul etmişlerdir.…”

Özet. 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.Anahtar Kelimeler: Ultra yüksek dayanımlı fiber katkılı beton, UYDFKB, Basınç dayanımı, Çelik lif The Effects of Fiber Length and Water/Cement Ratio on Compressive Strength of Ultra High Strength Fiber Reinforced ConcreteAbstract. 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 7 th , 14 th and 28 th 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.
