A Concise Review on Interlayer Bond Strength in 3D Concrete Printing

Interlayer bond strength is one of the key aspects 3D concrete printing. It a well-established fact that, similar to other printing process material designs, parameters and environment can significantly affect between layers printed concrete. The first section this review paper highlights importance strength, which mechanical durability properties structures. next summarizes all testing measurement methods adopted in literature, including microstructure characterization. Finally, last two sections focus on influence critical different strategies employed literature for improving via strengthening interlocking tailoring surface as well interface reactions. This concise work will provide holistic perspective current state art interlayer process.
