Özet:

 The use of additives such as slaked lime, fly ash, silica fume, tuff, marble dust to stabilize low strength clays is a very old and traditional practice. However, with the emergence of new technological products, these traditional stabilization methods have begun to give way to reinforcement methods, especially with products such as artificial fiber. One of these eco-friendly, natural and abundant materials used in soil reinforcement is basalt fiber, and its use is becoming more common day by day. The success of using basalt fiber in soil reinforcement is related to the size and ratio of the basalt fiber used, and scientific studies have focused on these issues. The aim of this study is to examine the effects of basalt fiber ratio on strength in high plasticity bentonite clay reinforced with basalt fiber. For this purpose, a number of experimental studies have been carried out. Unconfined compressive tests were carried out on cylindrical samples prepared by adding 6 mm long basalt fibers to clay at different rates and compressing them at optimum water content, and the changes in the strength of the soil were determined. The results of the study showed that the maximum strength was obtained at the rate of 4 basalt fiber in bentonite clay reinforced with basalt fiber of 6 mm length, while there was a decrease in strength at basalt fiber ratios higher than this ratio.

 Düşük dayanımlı killeri stabilize etmek amacıyla sönmüş kireç, uçucu kül, silis dumanı, tüf, mermer tozu gibi katkı malzemelerinin kullanımı oldukça eski ve geleneksel bir uygulamadır. Ancak yeni teknolojik ürünlerin ortaya çıkışıyla birlikte bu geleneksel stabilizasyon yöntemleri yerini özellikle yapay fiber gibi ürünlerle yapılan güçlendirme yöntemlerine bırakmaya başlamıştır. Zemin iyileştirmede kullanılan, çevre dostu, doğal, doğada bol miktarda bulunan bu malzemelerden biri de bazalt fiberdir ve kullanımları gün geçtikçe yaygınlaşmaktadır. Zemin güçlendirmede bazalt fiber kullanımının başarısı kullanılan bazalt fiberin boyutu ve oranı ile ilgilidir ve yapılan bilimsel çalışmalar bu konularda yoğunlaşmıştır. Bu çalışmanın amacı, bazalt fiber ile güçlendirilen yüksek plastisiteli bentonit kilinde bazalt fiber oranının dayanıma olan etkilerinin incelenmesidir. Bu amaçla bir dizi deneysel çalışma gerçekleştirilmiştir. 6 mm uzunluğundaki bazalt fiberlerin kile farklı oranlarda eklenmesi ve optimum su içeriğinde sıkıştırılmasıyla hazırlanan silindirik örneklerde serbest basınç deneyleri gerçekleştirilmiş ve zeminin dayanımında meydana gelen değişimler belirlenmiştir. Çalışmanın sonuçları, 6 mm uzunluğundaki bazalt fiber ile güçlendirilen bentonit kilinde maksimum dayanımın 4 bazalt fiber oranında elde edildiğini, bu orandan daha yüksek bazalt fiber oranlarında ise dayanımda azalmalar oluştuğunu göstermiştir.
