3D　concrete　printing　(3DCP)　is　used　to　manufacture　freeform　components　by　digitally　controlling　the　distribution　of　concrete　materials　without　requiring　additional　formwork.　Recurring　issues　associated　with　3DCP　are　low　tensile　strength　and　poor　ductility　of　the　nonreinforced　structures.　In　this　paper,　a　reconciliation　printing　methodology　is　presented　for　manufacturing　reinforced　geopolymer　structures　by　simultaneously　embedding　micro-cables　during　the　printing　process.　Structural　arched　beam　and　spiderweb-like　structures　were　3D　printed　and　used　to　verify　the　feasibility　of　the　proposed　reinforcing　method　by　evaluating　their　shape-based　structural　performance.　A　self-developed　loading　device　was　used　to　simulate　the　natural　tension-only　stress　condition　of　a　real　spiderweb.　The　loading　capacity　of　the　cable-reinforced　web　structure　was　calculated　and　compared　to　the　test　results,　which　verified　the　bonding　and　the　reconciliation　between　the　micro-cable　and　the　geopolymer　matrix.　As　compared　to　the　nonreinforced　structures,　the　failure　mode　of　the　reinforced　structures　changed　from　brittle　to　ductile　with　multiple　cracks,　and　the　micro-cable　reinforcement　altered　the　strain　evolution　patterns.　This　study　demonstrates　that　the　strength　of　the　reinforced　structure　was　substantially　increased.　Further,　both　the　method　of　reinforcement　and　the　specific　configuration　of　the　3D　printed　structures　play　a　crucial　role　in　resisting　deformation　and　damage.　(C)　2020　Elsevier　Ltd.　All　rights　reserved.
