Özet:

 The use of basalt fiber has become quite common in soil reinforcement works, which emerged as an alternative to traditional soil improvement methods and are carried out using different types of fibers. Basalt fiber, whose raw material is basalt rock, is preferred in soil reinforcement works due to its features such as high strength, economical, environmentally friendly, natural and abundant. In this study, the effects of basalt fiber reinforcement on the compressibility of high plasticity bentonite clay were examined. Bentonite clay was reinforced with 24 mm long basalt fiber at different rates between 0.5 and 5.0, and standard proctor tests were carried out on these mixtures. With experimental studies, maximum dry density γdmax and optimum water content Ꞷopt values were determined and the effects of basalt fiber reinforcement on these parameters were evaluated. According to the test results, while γdmax values increased up to 2.5 basalt fiber reinforcement ratio, Ꞷopt values decreased. In samples with basalt fiber ratio greater than 2.5, γdmax values decreased and Ꞷopt values increased. The results obtained showed that the basalt fiber ratio at which bentonite can be compressed best is 2.5, and basalt fiber reinforcement at rates greater than this ratio negatively affects the compressibility.

 Geleneksel zemin iyileştirme yöntemlerine alternatif olarak ortaya çıkan ve farklı türdeki fiberler kullanılarak yapılan zemin güçlendirme çalışmalarında bazalt fiber kullanımı oldukça yaygın hale gelmiştir. Hammaddesi bazalt kayası olan bazalt fiber, yüksek dayanımlı, ekonomik, çevre dostu, doğal ve bol miktarda bulunması gibi özelliklerinden dolayı zemin güçlendirme çalışmalarında tercih edilmektedir. Bu çalışmada bazalt fiber takviyesinin yüksek plastisiteli bentonit kilinin sıkıştırılabilirliğine olan etkileri incelenmiştir. Bentonit kiline 24 mm uzunluğunda ve 0.5 ile 5.0 arasında farklı oranlarda bazalt fiber takviyesi yapılmış ve bu karışımlarda standard proktor deneyleri gerçekleştirilmiştir. Deneysel çalışmalar ile maksimum kuru yoğunluk γdmax ve optimum su içeriği Ꞷopt değerleri belirlenmiş ve bazalt fiber takviyesinin bu parametrelere olan etkileri değerlendirilmiştir. Deney sonuçlarına göre, 2.5 bazalt fiber takviye oranına kadar γdmax değerleri artmakta iken, Ꞷopt değerleri ise azalmıştır. Bazalt fiber oranının 2.5dan daha fazla olduğu örneklerde ise γdmax değerleri azalmış, Ꞷopt değerleri ise artış göstermiştir. Elde edilen sonuçlar, bentonitin en iyi sıkıştırılabildiği bazalt fiber oranının 2.5 olduğunu ve bu orandan daha büyük oranlardaki bazalt fiber takviyesinin sıkıştırılabilirliği olumsuz yönde etkilediğini göstermiştir.
