One-Part Alkali-Activated Wood Biomass Binders for Cemented Paste Backfill

Minerals, Journal Year: 2025, Volume and Issue: 15(3), P. 273 - 273

Published: March 7, 2025

This study developed a one-part alkali-activated slag/wood biomass fly ash (WBFA) binder (AAS) for preparing cemented paste backfill (CPB) as an alternative to traditional cement. Through multi-scale characterizations (XRD, FTIR, TGA, rheological testing, and MIP) performance analyses, the regulation mechanisms of slag/WBFA ratios on hydration behavior, microstructure, mechanical properties were systematically revealed. Results demonstrate that high slag proportions significantly enhance slurry rheology strength, primarily through generating dense gel networks products promoting particle aggregation via reduced zeta potential. Although inert components in WBFA inhibit early hydration, long-term reactivity effectively counteracts these negative effects, achieving comparable 28-day compressive strength between slag/WBFA-based CPB (4.11 MPa) cement-based (4.16 MPa). Microstructural analyses indicate disordered gels AAS systems exhibit silicon–oxygen bond polymerization degrees (950 cm−1) cement, while regulates Ca/Si induce bridging site formation (900 cm−1), reducing porosity enhancing structural compactness. research provides theoretical support process optimization strategies developing low-cost, high-performance mine filling materials using industrial solid wastes, advancing sustainable green mining practices.
