Article Synopsis
- The study explores the activation of stainless steel refining slag using alkali-silicate solutions to create a high-value cementitious binder, focusing on the impacts of different activators.
- Higher concentrations of alkali-silicate correlate with increased heat generation and greater compressive strength, with sodium-based activators showing better early strength than potassium ones, though long-term strengths remain comparable.
- Analysis reveals that using potassium activators results in lower heavy metal leaching compared to sodium, suggesting that alkali type and solution composition significantly affect hydration and mechanical properties, promoting recycling of slag that would typically be discarded.
