Temiz ve kirletilmiş numuneler üzerinde dane boyu dağılımı, özgül ağırlık, likit limit, kompaksiyon ve direk kesme deneyleri gerçekleştirilmiştir. Sonuçlar, bakır kirliliğinin zeminin mikro yapısını ve mühendislik davranışını önemli ölçüde etkilediğini göstermektedir. Kirlenme sonucu özgül ağırlıkta hafif bir artış, likit limitte azalma, optimum su içeriğinde azalma ve maksimum kuru birim hacim ağırlıkta artma gözlemlenmiştir. En dikkat çekici değişiklik, içsel sürtünme açısındaki önemli düşüş olup, bu durumun bakır iyonlarının daneler arası sürtünmeyi azaltmasından kaynaklandığı düşünülmektedir. Elde edilen bulgular, ağır metal kirliliğine maruz kalan sahalarda mühendislik uygulamaları planlanırken dikkatli olunması gerektiğini ortaya koymaktadır.

Laboratory tests including grain size distribution, specific gravity, liquid limit, compaction, and direct shear were performed on both clean and contaminated samples. Results indicate that copper contamination significantly influences the microstructure and engineering behavior of the soil. A slight increase in specific gravity, a decrease in liquid limit, a decrease in optimum moisture content, and an increase in maximum dry unit weight were observed. The most notable change was a considerable decrease in internal friction angle, which is attributed to the lubricating effect of copper ions reducing interparticle friction. These findings emphasize the need for caution when designing engineering structures in copper-contaminated areas. CR - Akkoca, D. B., Yıldırım, I., & Al-Juboury, A. I. (2024).
