Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders
Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...
