Çok ince taneli yüksek fırın cüruflu çimento ile stabilize edilmiş düşük plastisiteli killi zeminin mühendislik özellikleri

Bu deneysel çalışmada, çok ince taneli yüksek fırın cüruflu çimento (Spinor A6) ile stabilize edilmiş düşük plastisiteli killi zeminin bazı mühendislik özelliklerinin belirlenmesi amaçlanmıştır. Öncelikle, %8, %10 ve %12 oranlarında Spinor A6 karıştırılarak elde edilen killi zemin numunelerinin temel geoteknik özellikleri deneysel olarak tespit edilmiştir. Daha sonra, optimum su muhtevası ve maksimum kuru birim hacim ağırlığında sıkıştırılmış Spinor A6 katkılı killi zemin numuneler üzerinde tek eksenli serbest basınç, sıkışabilirlik ve şişme deneyleri yapılmıştır. Deneysel veriler, düşük plastisiteli killi zeminin Spinor A6 ile stabilize edilme sonrası, 90. gün sonunda dayanımının açık ortamda bekletilen numunelerde 9 ile 14 kat, streçe sarılı halde bekletilmiş numunelerde 9 ile 12 kat arasında arttığını göstermiştir. Ayrıca 90. gün sonunda sıkışabilirliğin açık ortamda bekletilen numunelerde 18,3 ile 19,2 kat arasında, streçe sarılı halde bekletilmiş numunelerde ise 17,6 ile 18,5 kat arasında azaldığı tespit edilmiştir. Son olarak, şişme potansiyelinin ise 90. gün sonunda açık ortamda bekletilen numunelerde 67,5 ile 270,0 kat arasında, streçe sarılı halde bekletilmiş numunelerde ise 54,0 ile 101,2 kat arasında azaldığı belirlenmiştir.

Anahtar Kelimeler:

Spinor A6, stabilizasyon, killi zemin, dayanım, sıkışabilirlik, şişme
