Bu çalışmada kil bir zemine kireç katılmasının dayanıma etkisi araştırılmıştır. Çalışmanın amacı doğrultusunda katkı malzemesi olarak kullanılan kireç, kil zemininin içine ağırlıkça farklı yüzdelerde eklenmiştir. Hazırlanan karışımlarda, kil içine kilin ağırlığının %2,5, %5, %7,5, %10, %15 ve %20 oranlarında kireç eklenmiştir. Farklı oranlarda hazırlanan numuneler homojen olarak karıştırıldıktan sonra kıvam limitleri, kompaksiyon, serbest basınç ve Kaliforniya taşıma gücü oranı (CBR) deneyleri uygulanmıştır. Deneysel çalışmalar sonucunda, karışımdaki kireç artışına bağlı olarak numunelerin plastisite indeksi ve maksimum kuru yoğunluğu azalmış, optimum su muhtevası artmıştır. Ayrıca, 7 ve 28 günlük kür sürelerine tabi tutulan numuneler içerisinde en yüksek serbest basınç mukavemeti değeri %5 kireç oranında elde edilmiştir. Bu oranda yine aynı kür sürelerine tabi tutulan numunelerin CBR değerleri saf kil zemine göre sırasıyla 1,37 ve 2,08 kat yüksek sonuç vermiştir.
In this study, the impact of the resistance of the partition of a thick ground was studied. According to the purpose of the study, the curtain used as a additive material, was added to the curtain floor in different percentages of weight. In the prepared mixture, it was added to the flame with a percentage of 2.5%, 5%, 7.5%, 10%, 15% and 20% of the flame weight. The samples prepared in different proportions were mixed homogeneously, and the compaction limits, free pressure and California transportation power ratio (CBR) experiments were applied. As a result of experimental studies, due to the increase in curl in the mixture, the plasticity index of the samples and maximum dry intensity have decreased, the optimal water intake has increased. In addition, the highest freedom pressure strength value in the samples subject to 7 and 28 day curriculum periods was obtained at a rate of 5%. The CBR values of samples subject to the same curve period were 1,37 and 2,08 times higher, respectively, compared to the pure curve ground.
In this study, the effect of adding lime to clay soil on strength was investigated. For the purpose of the study, lime, which is used as an additive, was added to the clay soil in different percentages by weight. In the prepared mixtures, lime was added in 2.5%, 5%, 7.5%, 10%, 15% and 20% of the weight of clay. The samples prepared in different proportions were homogeneously mixed, and then compaction, unconfined compression and California bearing ratio (CBR) tests were performed. As a result of experimental studies, as the lime content in the mixture increased, the plasticity index and maximum dry density decreased while the optimum water content increased. In addition, the highest unconfined compressive strength value of the samples cured for 7 and 28 days was obtained at the rate of 5% lime. For this additive ratio, the CBR values of the samples cured at the same time were 1.37 and 2.08 times higher than the additive-free clay soil, respectively.
