Farklı katkılarla zemin stabilizasyonu uzun yıllardan beri geoteknik mühendislerinin ilgisini çekmektedir. Zemin stabilizasyonu ile zayıf zeminin taşıma kapasitesi arttırılmakta, toplam oturmalar azaltılmakta, dolgu ve şevlerin stabilitesi sağlanmakta, istinat duvarları desteklenmekte ve potansiyel sıvılaşma riskleri azaltılmaktadır. Bu metotlardan biri de zeminlerin katkı maddesi ile iyileştirilmesidir. Deney programında atık malzemenin değerlendirilmesi kapsamında stabilizasyon amacı ile polipropilen elyaf kullanılmıştır. Düşük ve yüksek plastisiteli killi zemine %0, %0.1, %0.5, %1.0, %1.5 polipropilen elyaf eklenmiştir. Çalışmada, hidrometre deneyi, özgül ağırlık deneyi, Atterberg limitleri, Standart proktor deneyi ve tek eksenli basınç dayanım deneyi yapılmıştır. Birleştirilmiş zemin sınıflandırma sistemine göre CL ve CH olarak belirlenen kil zemine elyaf ilave edilmesi, farklı kür süreleri sonunda mukavemet değerlerinde artışa neden olmuştur.

The Influence of Polypropylene Fiber on High and Low Plasticity Clay

Öz

Soil stabilization with different additives has attracted the attention of geotechnical engineers for many years. With soil stabilization, the bearing capacity of weak soil is increased, total settlements are reduced, the stability of fills and slopes is ensured, retaining walls are supported and potential liquefaction risks are reduced. One of these methods is the improvement of soils with additives. Polypropylene fiber was used for stabilization purposes within the scope of evaluation of waste material in the experimental program. 0%, 0.1%, 0.5%, 1.0%, 1.5% polypropylene fiber was added to low and high plasticity clay soil. In the study, hydrometer test, specific gravity test, Atterberg limits, Standard proctor test and uniaxial compressive strength test were performed. Adding fiber to the clay soil, designated as CL and CH according to the unified soil classification system, caused an increase in the strength values at the end of different curing periods.
