Advanced Concrete for 3D Printing: Material Development and Structural Integrity

Additive manufacturing of buildings is an emerging method of construction technology, which has potential to manufacture concrete structures. It encompasses investigation into novel concrete designs aspiring for suitability in 3D printing, with consideration given to their physical properties and the structural necessities surrounding the load-bearing requirements they must possess. Different additives, such as polymers and nanoparticles, are investigated to improve printability as well as mechanical characteristics and endurance and to overcome major issues in extrusion behavior, interlayer adhesion, and post-print curing mechanisms. Moreover, the research examines how deviations in mix design affect the mechanical properties of 3D printed concrete constructs, specifically, in terms of structural durability across varying environmental parameters. By grasping the relationship between these components, the discoveries offer further comprehension of how the plan of materials impacts the printability and long-term performance of the concrete used in 3D-printing, providing important data to direct what might happen uses of development.
