Uçucu Kül, Kireç ve Deniz Suyu ile Stabilize Edilen Bir Zeminin Dayanım Değerleri

Abstract

Sunulan bu çalışmada, uçucu kül (FA) ve kireç katkıları uygulanan bir zeminin dayanım değerleri, deneysel olarak incelenmiştir. Çalışmada katkıların etkilerinin yanında, yoğurma suyu olarak deniz suyu kullanılmasının etkisi de irdelenmiştir. Deneysel çalışmalarda, numuneler üzerinde Elek analizi, Kıvam limitleri, Proctor Deneyi, Serbest basınç (UCS) ve Kaliforniya taşıma oranı (CBR) deneyleri uygulanmıştır. Ayrıca FA'nın yapısal özelliklerini belirlemek için X-ışın kırılımı (XRF), Fourier dönüşümü kızılötesi (FT-IR) ve Taramalı Elektron Mikroskobu (SEM) analizleri uygulanmıştır. Deney sonuçları, zeminin UCS ve CBR değerlerinin sırası ile 134 kPa ve %3,1 olduğunu, 28 günlük kür sonucunda tüm katkıların birlikte kullanıldığı karışımda bu değerlerin sırası ile 846 kPa ve %16,3 değerine yükseldiğini göstermiştir.

Strength Values of a Soil Stabilized with Fly Ash, Lime, and Sea Water

Abstract

In this study, the strength values of a soil to which fly ash (FA) and lime additives treated were examined experimentally. In addition to the additives, the effect of using sea water as kneading water was also examined. In experimental studies, Sieve analysis, Consistency limits, Proctor Test, Unconfined compression (UCS) and California bearing ratio (CBR) tests were carried out on the samples. In addition, X-ray fluorescence (XRF), Fourier transform infrared (FT-IR) and Scanning Electron Microscopy (SEM) analyses were carried out to describe the structural properties of FA. Test results showed that the UCS and CBR values of the soil were 134 kPa and 3.1% respectively. After 28 days of curing, these values increased to 846 kPa and 16.3%, respectively, in the mixture which all additives were used together.
