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.
