Thermal and mechanical performance of 3D-printed excavated soil wall solidified by alkali-activated slag

Key Points

• Enhanced thermal performance correlates with alkali-activated slag as a solidifying agent, improving insulation.
• Mechanical performance shows a notable increase by 25% when utilizing specific printing techniques over traditional methods.
• Assessment using advanced fabrication techniques focuses on the properties of 3D-printed structures made from excavated soil.
• Highlights the possibility of sustainable construction practices through effective soil solidification with geopolymer technology.
