Time-controlled 3D printing of high-ductility cementitious composites with circumferential printing path for coating of prestressed concrete cylinder pipe

Cracking of the protective layer of prestressed concrete cylinder pipe (PCCP) induces steel wire corrosion and pipe bursts, threatening water conveyance safety. High-ductility cementitious composites (HDCC) offer excellent strain hardening and multi-cracking behavior, but convent...
