污染尾矿,例如，铁尾矿,可以用低碳地质聚合物稳定，作为路基回收利用，但是可持续性尚未得到全面评估。本研究从生命周期的角度建立了一个可持续的框架，由环境定量指标组成，社会,和经济,评估五个稳定案例(即，M1、M2、C1、C2和水泥)。此外，采用改进的AHP（层次分析法）-CRITIC（标准间相关性的标准重要性）-TOPSIS（通过与理想解决方案相似的偏好顺序技术）模型来选择最可持续的稳定方法。使用地质聚合物的四个案例的可持续性得分高于水泥案例（0.22），与C2（0.75），C1(0.64),M1（0.56），和M2(0.54)，分别。敏感性分析证实，评估结果相对稳定，特别是当经济的主观权重不是最高的时候(水泥对应方具有经济优势)。这项研究构成了一种新的方法来补充可持续稳定案例的选择，弥合了专注于绿色稳定性能的差距。
Contaminated tailings, e.g., iron tailings, could be stabilized by low-carbon geopolymers for recycling as road base, but the sustainability has yet to be evaluated comprehensively. This study developed a sustainable framework from the life cycle perspective, consisting of quantitative indicators in environment, society, and economy, to assess five stabilization cases (i.e., M1, M2, C1, C2, and cement). Moreover, a modified AHP (Analytic Hierarchy Process)-CRITIC (CRiteria Importance Through Inter-criteria Correlation)-TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) model was applied to select the most sustainable stabilization method. The sustainability scores of four cases using geopolymers were higher than that of the cement
case (0.22), with C2 (0.75), C1 (0.64), M1 (0.56), and M2 (0.54), respectively. Sensitivity analysis confirmed that the assessment results were relatively stable, especially when the subjective weight of the economy was not the highest (the cement counterpart had economic advantages). This study constituted a novel approach to complement the selection of sustainable stabilization cases, bridging the gap of focusing exclusively on green stabilization performance.
