Effects of Early-Age rheology and printing time interval on Late-Age fracture characteristics of 3D printed concrete

•Fracture of 3D printed concrete is strongly affected by rheology and printing process.•Increasing printing time interval changes rheology and decreases fracture toughness.•Time effect is stronger on fracture characteristics of interlayers than filaments.•Dynamic oscillation sweep method reveals tim...
