Abstract

This research was carried out to determine the strength changes in the freeze-thaw test result of clay soil reinforced with goat hair fibers, a natural material. 0.5%, 1%, 1.5%, and 2% Goat Hair fibers were added to the clayey soil used in this study. Strengthening of fine and coarse-grained soils with natural additives with weak geotechnical properties has been the main subject of many studies in recent years. In this study, curing times of 1, 7, and 28 days and 12 freeze-thaw cycles were applied to the mixture samples. A cycle was completed by placing the samples in a 24-hour adjustable freeze-thaw cabinet at -21°C and then at +21°C for 24h.It has been determined that the additive added with the uniaxial compressive strength test increase the resistance of clayey soil before and after freezing-thawing. The most suitable mixture was determined as clay+1.5% Goat hair fiber after 28 days of curing.

Özet

Bu araştırma, doğal bir malzeme olan keçi kılı lifleri ile takviye edilmiş killi zeminin donma-çözülme testi sonucundaki dayanım değişikliklerini belirlemek amacıyla yapılmıştır. Bu çalışmada kullanılan killi zemine % 0.5, %1, %1,5 ve %2 Keçi Kılı lifleri ilave edilmiştir. İnce ve iri taneli zeminlerin doğal katkı maddeleri ile zayıf jeoteknik özellikleri güçlendirilmesi son yıllarda birçok çalışmanın ana konusu olmuştur. Bu çalışmada karışım numunelerine 1, 7 ve 28 günlük kür süresi ve 12 donma-çözülme döngüsü uygulanmıştır. Numuneler 24 saat ayarlanabilir dondurma-çözdürme kabinine -21°C'de ve +21°C'de 24 saat yerleştirilmesiyle bir döngü tamamlanmıştır. Tek eksenli basınç dayanımı testi ile eklenen katkı maddesinin killi zeminin donma-çözülme öncesi ve sonrası direncini artırdığı belirlenmiştir. En uygun karışım 28 günlük kür sonrasında Kil +%1.5 Keçi kılı lifi olarak belirlenmiştir.
