Bu çalışma, silisyum dioksit (SiO2) nanoparçacıkları ile yüksek fırın cürufu karışımının ince daneli zemin stabilizasyonundaki etkisini araştırmaktadır. Bu çalışmanın ana amacı, SiO2 nanoparçacıkları ve yüksek fırın cürufu kullanarak stabilize edilmiş ince daneli zeminin kompaksiyon özelliklerini (maksimum kuru yoğunluk ve optimum su içeriği) değerlendirmektir. Stabilize edilmiş ince daneli zeminlerin kompaksiyon özelliklerini elde etmek için standart proktor testleri yapılmıştır. Zeminin farklı yüksek fırın cüruf yüzdeleri (%10, %20,%30 ve %40) ve küçük miktarlarda (%1 ve %1.5) SiO2 nanoparçacıkları ile karıştırıldığı iki farklı tip numune hazırlanmıştır. Yüksek fırın cürufunun etkisi ve SiO2 nanoparçacıklarının yüksek fırın cürufu ile karışımının etkisi ayrı ayrı incelenmiştir. Test sonuçları, yüksek fırın cüruf içeriğindeki artışla birlikte maksimum kuru yoğunlukta bir düşüş olduğunu ortaya koymuştur. Ayrıca, zemine yüksek fırın cüruflu ile SiO2 nanopartiküllerinin eklenmesi maksimum kuru yoğunluğu arttırmıştır. Elde edilen sonuçlar küçük miktarlardaki SiO2 nanopartiküllerinin genellikle kompaksiyon özelliklerini iyileştirdiğini göstermektedir.

Effects of the mixture of nanoparticle silicon dioxide (SiO2) with blast furnace slag on the compaction characteristics

Öz

This study investigates the effect of using the mixture of silicon dioxide (SiO2) nanoparticles with blast furnace slag in fine grained soil stabilization. The main motive of this study is to evaluate the compaction characteristic (maximum dry density and optimum water content) of stabilized fine-grained soil using SiO2 nanoparticles and blast furnace slag. The standard proctor tests were conducted to obtain compaction characteristics for stabilized fine-grained soils. Two different types of samples were prepared in which soil was mixed with different blast furnace slag percentages (10%, 20%, 30%, and 40%) and small amounts (%1 and 1.5%) of SiO2 nanoparticles. The effect of the blast furnace slag and the mixture of SiO2 nanoparticles with blast furnace slag were investigated, separately. The test outcomes revealed that a decrease in maximum dry density with the increase in blast furnace slag content. Moreover, the addition of SiO2 nanoparticles with blast furnace slag to the soil increased the maximum dry density. The obtained results show that the small amount of SiO2 nanoparticles generally improves compaction characteristics.
