Abstract

Bu çalışmada, benzer işlenebilirliğe sahip farklı boyut (makro ve mikro) ve narinlikteki çelik lif takviyeli kendiliğinden yerleşen beton (KYB) karışımların mühendislik ve işlenebilirlik özellikleri araştırılmıştır. Bu amaçla, lifsiz, sadece makro lif ve karma lif içeren KYB olmak üzere toplamda üç adet karışım tasarlanmıştır. Lifli KYB karışımları, EFNARC (2002) komitesi tarafından önerilen kriterlere göre mümkün olan benzer işlenebilirlik esas alınarak elde edilmiştir. Bu sebeple, çökme-yayılma, t500 ve J-halkası işlenebilirlik testleri yapılmıştır. Elde edilen lifli KYB karışımlarından 3, 28 ve 90 günlük basınç, yarmada çekme ve eğilmede çekme dayanımlarının belirlenmesi için numuneler hazırlanmış ve standartlara uygun şekilde test edilmiştir. Sonuç olarak, karışıma hem tekli hem de karma lif ilave edilmesi, karışımların işlenebilirlik özelliklerini olumsuz etkilemiştir. Bunun yanında, KYB karışımlarına narinliği 87 olan düz mikro çelik liflerin ilave edilmesinin basınç ve yarmada çekme dayanımlarında, narinliği 65 olan kancalı uçlu makro çelik liflerin ilave edilmesinin ise eğilmede çekme dayanımı değerlerinde olumlu bir etkiye sahip olduğu bulunmuştur.

Investigation of Workability and Engineering Properties of Hybrid Fiber Reinforced SCC Mixtures

Abstract

In this study, the engineering and workability properties of different size (macro and micro) and aspect/ratio steel fiber reinforced self-compacting concrete (SCC) mixtures with similar workability was investigated. For this purpose, a total of three SCC mixtures were designed: control with no fiber, only macro and hybrid fiber reinforced SCC. Based on possible similar workability, fiber reinforced SCC mixtures were obtained according to criteria recommended by the EFNARC (2002) committee. Therefore, slump-flow, t500 and J-ring workability tests were performed. Specimens obtained from SCC mixtures with fiber were prepared for 3, 28 and 90-day and compressive, splitting tensile and flexural tensile strengths tests were carried out. In conclusion, the inclusion of both single and hybrid fiber to SCC mixtures negatively affected the workability properties of the mixtures. Besides, it was found that the addition of straight micro steel fibers with an aspect ratio of 87 to mixtures had a positive effect on the compressive and splitting tensile strengths while the addition of hook-end macro steel fibers with an aspect ratio of 65 had a positive effect on the flexural tensile strength values.
