Abstract

fetched live from OpenAlex

While increasing studies have incorporated carbonation into chemical stabilization of soils, a scarcity of research has focused on carbonation progress, carbonation effects on pH, dynamic properties, and brittleness of stabilized soils. None of these studies has been concerned with loess. To address these issues, this study proposes a novel and sustainable approach, which used lignin–MgO to integrate mineral carbonation into loess stabilization. This integrated approach enabled realizing mechanical property enhancement, alkalinity reduction, and CO 2 sequestration. A comprehensive experimental program was conducted to evaluate the efficacy of this method. The results revealed that the proposed method could mineralize approximately 6% of CO 2 relative to the dried mass of loess–binder mixture within 24 h of carbonation; addition of CO 2 reduced pH values in stabilized loess from 10.3 to 8.2, and carbonation increased the early strength of stabilized loess by 50%. Furthermore, addition of lignin was found to reduce the brittleness and improve the freeze–thaw durability of stabilized loess. Finally, based on comprehensive mineralogical and microstructural analyses, a conceptual model was proposed to explain the mechanisms of carbonation and stabilization for loess.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
