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 ... -
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 ...
