Abstract

To minimize or to eliminate the swelling potential of an expansive soil, some chemicals such as lime, cement, fly ash and organic materials can be used. Lime is commonly adopted for stabilization of expansive soils, because of its effectiveness in utilization. This paper briefly describes swelling soils and the factors acting on the swell mechanism, discusses the lime mixture for controlling the swell potential and introduces the results of a study applied to investigate the performance of the mixture of hydrated lime-clay, belonging to samples collected from the campus area of Eskişehir Osmangazi University in Eskişehir. In this study, the samples belonging to three different locations were compacted at the standard and modified compaction efforts, and then swell tests were carried out by considering lime mixture at different percentages (0,1,3 and 5 percent of dry soil weight). For this purpose, 88 specimens were used to measure the free swell percent. As a result of this study, the stabilization of high plasticity clay can be sufficiently provided by the hydrated lime mixture, the significant effect on the mixtures is possible after 3 percent of the hydrated lime. It is also seen from the study that the effect of lime mixture is more effective on the specimen series prepared as considering the modified energy input.

Özet

Şişme potansiyeline sahip temel zemininin stabilizasy onunda kireç, çimento, uçucu kül ve bazı organik bileşikler gibi katkı maddeleri kullanılmaktadır. Bunlardan kireç katkısı; etkili kullanımı nedeniyle yaygın uygulama alanı bulmuştur. Bu çalışmada; Eskişehir Osmangazi Üniversiteni kampus alanında yer alan yüksek şişme potansiyeline sahip Meşelik killerinin kireç katkısı ile stabilizasyonu araştırılmıştır. Araştırmada sönmüş kireç katkısı-şişme yüzdesi ilişkisi, şişme yüzdesinin zamanla-değişimi ve şişme yüzdesi-nihai su muhtevası değişimi incelenmiştir. Bu amaçla üç ayrı lokasyondan alınan, standart ve modifiye enerji seviyelerinde ve farklı sönmüş kireç katkı yüzdelerinde (% O, 1, 3 ve 5) hazırlanmış 88 ayrı numune üzerinde klasik ödometre cihazı ile serbest şişme yüzdesi deneyleri yapılmıştır. Deneyler sonunda, sönmüş kireç katkısının killerin şişme potansiyelinin kontrolünde başarıyla kullanılabileceği, bu katkının % 3 seviyesinden sonra etkili olduğu ve etkinin yüksek enerji seviyesinde nispi olarak daha yüksek görüldüğü belirlenmiştir.
