Ultra-early strength and carbon benefits alkali-activated materials based on carbonation steel slag

Key Points

• Ultra-early strength improves significantly with alkali-activated materials made from steel slag, impacting construction timelines.
• The carbon benefits demonstrate a promising avenue for carbon dioxide capture through carbonation processes in these materials.
• Analysis of carbonation and material performance indicates substantial gains in both durability and sustainability metrics over traditional methods.
• Supporting the transition to greener construction practices, these findings highlight the potential of steel slag in reducing carbon footprints.
