Implication

This evaluation shows improved printability and thermal conductivity in 3D concrete printing mixtures with recycled materials, suggesting a sustainable pathway.

Key Points

Narrow particle size distributions improved extrudability in 3D concrete printing mixtures.
Incorporating recycled aggregates boosted compressive strength levels up to 6%, enhancing overall material performance.
Lightweight fillers effectively reduced thermal conductivity while varying effects on compressive strength depended on the filler used.
All tested mixtures retained printability, demonstrating the feasibility of integrating recycled materials without significant loss of performance.
