Synergistic enhancement mechanism of hydration and carbonation and performance optimization for steel slag-cement foam concrete: Regulatory role of CO2 injection mixing process

Key Points

• Enhanced performance results from the synergistic effects of hydration and carbonation in foam concrete.
• Key evidence shows a significant increase in material strength by up to 20% with CO2 injection.
• Analysis focused on the mixing process and its influence on the interaction between components.
• Results may inspire future innovations in sustainable construction materials using steel slag.
