초록

Concrete structures built by 3D printing technology is formed as the several concrete layers. Thus, 3D printing technology for concrete structure could have less strength than the design. In this study, fracture energy (fracture toughness) tests for layered concrete in various condition was performed. depending on required time for stacking new layer. Based on the results of performed tests, it was found that fracture energy was decreased due to increased non-bonded time.
