Özet:

 In this study, the effect of sodium alginate biopolymer and the effectiveness of sodium alginate biopolymer combined with lime in improving a high-plasticity clay soil were investigated. For this purpose, 0, 0.5, 1, and 1.5 biopolymers and 0, 2, 4, and 6 lime were added to the clay soil. At the end of the 7 and 28 day curing period, the strength results were evaluated with unconfined compressive strength tests. In order to examine the effects of environmental factors, the improved soil samples were exposed to freeze-thaw cycles for 5 and 10 cycles. As a result, it was observed that sodium alginate biopolymers had higher unconfined compressive strengths compared to pure samples at the end of the curing periods. As a result of freeze-thaw cycles, it was determined that the biopolymer additive improved the strength results. When using biopolymer with lime, it was determined as a result of strength tests and freeze-thaw cycles that biopolymer increased the effectiveness of lime in soil improvement. As a result, it has been evaluated that sodium alginate, an environmentally friendly biopolymer, may have positive contributions to engineering applications in the improvement of clay soils.

 Bu çalışmada yüksek plastisiteli bir kil zeminin iyileştirilmesinde sodyum aljinat biyopolimerinin ve kireçle birlikte sodyum aljinat biyopolimerinin etkinliğinin iyileştirmeye etkisi araştırılmıştır. Bu amaçla kil zemine 0, 0,5, 1 ve 1,5 oranlarında biyopolimer ve 0, 2, 4 ve 6 oranlarında kireç ilave edilmiştir. 7 ve 28 günlük kür süresi sonunda mukavemet sonuçları serbest basınç mukavemeti deneyleri ile değerlendirilmiştir. Çevresel etkilerin etkisinin incelenebilmesi amacıyla da iyileştirilen zemin örnekleri 5 ve 10 döngü olarak donma-çözülmeye maruz bırakılmıştır. Sonuç olarak kür süreleri sonunda sodyum aljinat biyopolimerinin katkısız numunelere kıyasla daha yüksek serbest basınç mukavemetlerine sahip olduğu görülmüştür. Donma çözülme döngüleri sonucunda da biyopolimer katkısının mukavemet sonuçlarını iyileştirdiği belirlenmiştir. Kireçle birlikte biyopolimer kullanımında ise biyopolimerin zemin iyileştirmede kirecin etkinliğini artırdığı mukavemet deneyleri ve donma çözülme döngüleri sonucunda belirlenebilmiştir. Sonuç olarak çevre dostu bir biyopolimer olan sodyum aljinatın kil zeminlerin iyileştirilmesindeki mühendislik uygulamalarına olumlu katkılarının olabileceği değerlendirilmiştir.
