Implication

Randomized trial evaluates the mechanical performance of alkali-activated binders using ladle furnace slag and biomass ash, suggesting a sustainable recycling approach.

Key Points

This study investigates the combined effects of ladle furnace slag and biomass bottom ash in improving the performance of alkali-activated binders.
Activated blends of ladle furnace slag and biomass bottom ash using potassium-based alkaline solution.
Evaluated mechanical properties over a period of 90 days.
Used X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy to analyze microstructural development.
Binders with 75 wt% biomass bottom ash achieved maximum compressive strength of 11.1 MPa and flexural strength of 2.9 MPa.
Higher biomass ash content improved mechanical properties due to increased availability of amorphous silica.
Co-activation led to the formation of stable hybrid (K,C)-A-S-H gel and refined pore structure.
