Admixture effects on the rheological/mechanical behavior and micro-structure evolution of alkali-activated slag backfills
Ji, Xubo; Gu, Xiaozhong; Wang, Zhuoran; Xu, Shuai; Jiang, Haiqiang; Yılmaz, Erol (MDPI, 2023)Recently, alkali-activated slag (AAS) has attracted extensive attention in cemented paste backfill (CPB) due to its low cost/CO2 emissions and high strength benefits. However, a comprehensive analysis of the mechanical/rheological ... -
Effect of mineral admixtures on flow properties of fresh cemented paste backfill: Assessment of time dependency and thixotropy
Jiang, Haiqiang; Fall, Mamadou; Yılmaz, Erol; Li, Yuanhui; Yang, Lei (Elsevier, 2020)Cemented paste backfill (CPB), an engineered mix consisting typically of tailings, cement and water, has become a regularly used structural material in most mines worldwide. the performance of the CPB structure is dependent ... -
Rheological properties of cemented paste backfill with alkali-activated slag
Kou, Yunpeng; Jiang, Haiqiang; Ren, Lei; Yılmaz, Erol; Li, Yuanhui (Mdpi, 2020)This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have ... -
Slag-based stabilization/solidification of hazardous arsenic-bearing tailings as cemented paste backfill: Strength and arsenic immobilization assessment
Jiang, Haiqiang; Zheng, Jingru; Fu, You; Wang, Zhuoran; Yılmaz, Erol; Cui, Liang (Elsevier, 2024)The widespread occurrence of toxic arsenic in sulfidic and non-ferrous waste tailings hinders its disposal as cement paste backfill (CPB). Alkali activated slag (AAS) has recently begun to be practiced as an alternative ... -
Strength analysis and optimization of alkali activated slag backfills through response surface methodology
Dai, Xinghang; Ren, Lei; Gu, Xiaozhong; Yılmaz, Erol; Fang, Kun; Jiang, Haiqiang (Frontiers Media, 2022)The significant difference in water-to-binder ratio, activator type and concentration between alkali-activated slag (AAS) paste/mortar/concrete and AAS-based cemented paste backfill (AAS-CPB) means that previous results ... -
Study of early-age performance of cementitious backfills with alkali activated slag under internal sulfate attack
Jiang, Haiqiang; Han, Jing; Ren, Lei; Guo, Zhenbang; Yılmaz, Erol (Elsevier, 2023)The vulnerability to internal sulfate attack of calcium-rich ordinary Portland cement (OPC) and its relative high cost force mines to explore technically effective and low cost alternative binders to solidify sulfate-containing ...
