Characterizing mechanical and multiscale porosity features of cementitious high sulfur tailings backfill using CT technology
He, Qianru; Cao, Shuai; Yılmaz, Erol (Elsevier, 2025)Since cementitious high sulfur tailings backfill (CHSTB) produces acidification during mine filling, it severely affects the environment of underground mining and filling strength in a timely manner. Therefore, the current ... -
Compression performance and microscopic mechanism of cemented high-sulfide tail fills under varying pH levels: The role of alkaline agents
He, Qianru; Cao, Shuai; Yılmaz, Erol (Elsevier, 2025)Sulfur-rich tailings are highly susceptible to acid generation during the filling process, which can adversely affect the pH and compressive properties of cementitious backfill. Hence, this study conducted an exploratory ... -
Influence of alkaline agents with different contents on strength features, energy dissipation and microscopic behavior of cement-based high‑sulfur tailings fill
He, Qianru; Yılmaz, Erol; Sun, Lijuan; Cao, Shuai (Elsevier, 2024)As high‑sulfur tails encompass abundant pyrite (FeS2), it is easy to form acidic/leachate waters under the action of water and air, which is opposed to cement-based tail fill (CTF)’s strength development. Therefore, the ...
