Overview

Review reveals recycled aggregates and by-products can enhance performance in 3D concrete printing, indicating sustainability benefits.

Key Points

  • Recycled-based 3D printable concretes can maintain or enhance structural performance while reducing environmental impact.
  • Mix-level life-cycle analyses report CO2 reductions typically ranging from 20% to 50%, largely influenced by recycled constituents.
  • Focus on mechanical strength, rheology, and fire resistance demonstrates the feasibility of using recycled materials in 3D printing.
  • The integration of recycled aggregates supports pathways toward durable and environmentally responsible construction methodologies.
