AB  - Bu çalışmada, yüksek plastisiteli kil (CH) zeminlerin sentetik vollastonit (SV) katkısı ile stabilize edilerek mühendislik özelliklerindeki değişim deneysel olarak araştırılmıştır. Stabilizasyon amacıyla laboratuvar ortamında %25 Na-bentonit ve %75 kaolinit içeren yapay zemin hazırlanmış; %0, %2, %4, %6, %8 ve %10 oranlarında SV katkısı ilave edilerek zemin numuneleri oluşturulmuştur. Zeminlerin kıvam limitleri ve serbest basınç dayanımı (UCS) belirlenmiş, katkının etkisi karşılaştırmalı olarak değerlendirilmiştir. Ayrıca katkının mikroyapısal etkilerini incelemek amacıyla SEM ve EDS analizleri gerçekleştirilmiştir. Deneysel bulgular, SV katkısının plastisite indeksinde %33 oranında azalma sağladığını, UCS değerlerinde ise katkısız zemine göre %203’e varan artışa neden olduğunu göstermektedir. Mikroyapı analizleri, sentetik vollastonitin fiziksel özellikleriyle zemin davranışını olumlu yönde etkileyerek stabilize edici bir katkı malzemesi olarak kullanılabileceğini ortaya koymaktadır.

N2  - In this study, the effects of synthetic wollastonite (SV) on the engineering behavior of high-plasticity clay (CH) soils were experimentally investigated. For stabilization purposes, an artificial clayey soil composed of 25% Na-bentonite and 75% kaolinite was prepared in the laboratory, and synthetic wollastonite was added at varying dosages of 0%, 2%, 4%, 6%, 8%, and 10% by weight. Atterberg limit tests and unconfined compressive strength (UCS) tests were conducted to evaluate the impact of SV addition. Furthermore, SEM and EDS analyses were performed to assess microstructural changes in the stabilized soils. The experimental results indicated that the plasticity index decreased by up to 33%, while UCS values increased by approximately 203% compared to the untreated soil. Microstructural analyses revealed that synthetic wollastonite positively influences the behavior of the soil through its physical characteristics, indicating its potential as an effective stabilizing additive.
