Anisotropic Behavior of 3D-Printed Concrete: Interlayer Bonding, Pore Architecture, Reinforcement Limitations, and Durability Mechanisms

The structural use of three-dimensional concrete printing remains limited by the directional weakness introduced during extrusion and layer-by-layer deposition. Although 3DPC offers major advantages in formwork elimination, architectural freedom, and automated construction, its printed architecture produces interfaces,...

Interface-Controlled Structural Behaviour of 3D Printed Concrete: Lessons from Masonry for Anisotropy, Print-Path Design and Standardisation

The structural application of 3D printed concrete (3DPC) is still constrained by the difficulty of qualifying a layered, process-dependent material using standards developed mainly for cast concrete and conventional masonry. This review examines 3DPC through masonry construction to clarify how interface-controlled beha...

Optimizing the Composition of Fiber-Reinforced Concrete Airfield Pavements to Improve Performance and Prevent Cracking

Concrete airfield pavements often experience premature failure due to extensive cracking under repeated loading and environmental exposure. Traditional single-scale fiber reinforcement methods have proven inadequate in controlling both micro- and macro-cracks, prompting the need for hybrid solutions. This study investi...
