Fine-grained soils present engineering challenges. Stabilization with marble powder has shown promise for improving engineering properties. Understanding the temporal evolution of Unconfined Compressive Strength (UCS) and geotechnical properties in stabilized soils could aid strength assessment. This study investigates the stabilization of fine-grained clayey soils using waste marble powder as an alternative binder. Laboratory experiments were conducted to evaluate the geotechnical properties of soil–marble powder mixtures, including Atterberg’s limits, compaction characteristics, California Bearing Ratio (CBR), Indirect Tensile Strength (ITS), and Unconfined Compressive Strength (UCS). The effects of various factors, such as curing time, molding water content, and composition ratios, on UCS, were analyzed using Exploratory Data Analysis (EDA) techniques, including histograms, box plots, and statistical modeling. The results show that the CBR increased from 10.43 to 22.94% for unsoaked and 4.68 to 12.46% for soaked conditions with 60% marble powder, ITS rose from 100 to 208 kN/m2 with 60–75% marble powder, and UCS rose from 170 to 661 kN/m2 after 28 days of curing, molding water content (optimum at 22.5%), and composition ratios (optimum at 60% marble powder). Complex modeling yielded R2 (0.954) and RMSE (29.82 kN/m2) between predicted and experimental values. This study demonstrates the potential of utilizing waste marble powder as a sustainable and cost-effective binder for soil stabilization, transforming weak soils into viable construction materials.

“…Elde ettikleri sonuçlar atık mermer tozları ile stabilize edilen kırmızı çöl kumlarının plastisitesinin düştüğünü ve CBR değerlerini yükseldiğini göstermiştir. Bu çalışmanın üzerinden 20 yıldan uzun bir süre geçmesine rağmen günümüzde dünya çapında 100 milyon tonluk üretim kapasitesine ulaşan mermer endüstrisinin ortaya çıkardığı atıklar nedeniyle mermer toz atıklarının tek başlarına veya başka malzemelerle karıştırılarak zayıf zeminlerin mühendislik özelliklerini iyileştirmek için kullanımıyla ilgili araştırmalar halen sürmektedir [18]. Saygılı [19] araştırmasında şişen killerin stabilizasyonu için atık mermer tozunun kullanılma olasılığını, kesme mukavemeti parametreleri ve mikro yapısal değişimleri inceleyerek ele almıştır.…”

Mermer kullanımının artmasına bağlı olarak, ortaya çıkan mermer atıkları dünya çapında önemli bir çevre sorunu haline gelmiştir. Sürdürülebilirliğin önemli olduğu günümüzde bu tür atıklar inşaat işlerinde çeşitli amaçlar için kullanılmaktadır. Sürdürülebilirliğe en büyük katkı, atık maddelerin yeniden kullanımıdır. Yapılan deneysel ve hesaplamalı çalışmada, üç farklı atık mermer tozunun zemin stabilizasyon malzemesi olarak kullanılabilirliği araştırılmıştır. Çalışmanın deneysel kısmında atık mermer tozları % 0-10-20-30 ve 40 oranlarında iki farklı CL sınıfı killi zemine eklenmiş ve zeminlerin mukavemet özelliklerindeki değişiklikler Atterberg limitleri, standart Proctor sıkıştırma, kesme kutusu, ve Kaliforniya taşıma oranı (CBR) testleri ile izlenmiştir. Hesaplamalı kısımda ise CBR ve AASHTO-93yöntemleri kullanılarak yapılan stabilizasyonun üstyapı kalınlığına etkileri belirlenirken, KENPAVE yazılımı ile Mekanistik-Amprik tasarım metoduna uygun olarak mermer tozu iyileştirmesinin üstyapının yorulma ömrüne olan katkısı araştırılmıştır. Elde edilen test sonuçları mermer toz atıklarıyla stabilize edilen düşük plastisiteli killerin dayanım özelliklerinin iyileştiğini göstermiştir. CBR ve AASHTO-93 metotları ile bu iyileştirmenin gereken üstyapı kalınlığını azaltabileceği, SN sayısındaki azalma ile karayolu imalatında yüzlerce metreküp malzeme kazancı sağlanabileceği hesaplanmıştır. Mekanistik-Amprik yöntem ile yapılan hesaplar da atık mermer tozu stabilizasyonu ile üstyapının kritik tekerlek izi oturması ömrünün ortalama %86’ya kadar artabileceğini öngörmektedir.

“…During the last few decades, scholars have conducted extensive investigations on the mechanical properties of frozen–thawed soils and summarized the variation rules of different soil mechanical properties under varying conditions. The results show that the compressive strength 7 , cohesion 1 , friction angle 8 and other soil properties are greatly changed after freezing and thawing and that the variations in soil characteristics are affected by many factors, such as the freezing temperature 9 , strain rate 10 and number of freeze‒thaw cycles 11 – 13 . However, these experiments are costly and time-consuming, especially when the number of freeze‒thaw cycles is large.…”

Seasonally frozen soils are exposed to freeze‒thaw cycles every year, leading to mechanical property deterioration. To reasonably describe the deterioration of soil under different conditions, machine learning (ML) technology is used to establish a prediction model for soil static strength. Six key influencing factors (moisture content, compaction degree, confining pressure, freezing temperature, number of freeze‒thaw cycles and thawing duration) are included in the modelling database. The accuracy of three typical ML algorithms (support vector machine (SVM), random forest (RF) and artificial neural network (ANN)) is compared. The results show that the ANN outperforms the SVM and RF. Principal component analysis (PCA) is combined with the ANN, and the PCA–ANN algorithm is proposed, which further improves the prediction accuracy. The deterioration of soil static strength is systematically researched using the PCA–ANN algorithm. The results show that the soil static strength decreased considerably after the first several freeze‒thaw cycles before the strength plateau occurred, and the strength reduction increased significantly with increasing moisture content and compaction degree. The PCA–ANN model can generate a reasonable prediction for the static strength or other soil properties of seasonally frozen soil, which will provide a scientific reference for practical engineering.
