Nano-CuO İle Hazırlanan Kompozit Kil Karışımlarının Kıvam Limitleri, pH ve Elektrik İletkenlik Özelliklerinin İncelenmesi

Öz

Nano malzemelerin kullanım alanları her geçen gün artmaktadır. Günümüzde birçok alanda olduğu gibi inşaat mühendisliğinde de nano partiküllerin kullanılabilirliği araştırmacıların dikkatini çekmektedir. Çalışma kapsamında, % 0.5, %1, %2 ve %3 oranlarında nano-CuO, yüksek plastisiteli kil ile interkalasyon yöntemi kullanılarak karıştırılmış ve elde edilen kompozit kil örneklerinin kıvam limitleri, pH ve elektrik iletkenlik özelliklerinin nano-CuO oranı ile değişimi incelenmiştir. Nanopartikülün eklenmesi likit limit değerlerini arttırırken, plastik limit değerlerinde göreceli olarak bir düşüşe neden olmuştur. Diğer taraftan, nano-CuO katkı oranı arttıkça pH ve elektrik iletkenlik değerlerinin arttığı tespit edilmiştir.

Investigation of Liquid Limit, pH and Electrical Conductivity Properties of Composite Clay Mixtures Prepared With Nano-CuO

Öz

The usage areas of nano materials are increasing day by day. As in many other fields, the availability of nano-particles in civil engineering attracts the attention of researchers. In this study, 0.5%, 1%, 2% and 3% nano-CuO was mixed with high plasticity clay by using intercalation method and the changes of consistency limits, pH and electrical conductivity properties with nano-CuO ratio of the composite clay samples were investigated. The addition of the nanoparticle increases the liquid limit values, also resulting in a relative decrease in the plastic limit values. On the other hand, as the ratio of nano-CuO additives increases, pH and electrical conductivity values increase.
