Abstract Weaving, a pivotal technique in human construction activities since the Neolithic era, remains unattainable modern concrete construction. Here, novel particle‐polymer coalescence strategy is proposed, which involves electrostatic, bridging, coordinating, and hydrogen bonding interactions, to establish balanced particle cohesion, enabling fabrication of stretchable cement slurry. The bending, knotting, coiling, winding, interlacing filaments for structural textiles successfully realized beyond traditional formwork casting, grouting, 3D‐printing, fabricate first‐ever Chinese knot woven with cement. Weaving builds triaxially cross‐penetrating structure that greatly promotes interlayer strength toughness by ≈208.5% 676.5% compared state‐of‐the‐art layer‐by‐layer 3D printed structure. These findings not only make breakthrough technology but also provide solutions fabricating multi‐directional structures great engineering‐application potentials.

Self-healing hydrogels can autonomously repair damage, enhancing their performance stability and broadening applications as soft devices. Although the incorporation of dynamic interactions enhances self-healing capabilities, it simultaneously weakens hydrogels’ strength. External stimuli such heating, while accelerating healing process, may also lead to dehydration. Developing a stable strategy that combines rapid high mechanical strength is challenging. Here, we introduce “salt-welding” for high-strength with room temperature self-healing. This achieved through borate ester bonds in salt-responsive poly(methacrylamide) hydrogel. The process involves “salt-fusion” convert fractures into viscous liquid swift healing, followed by “salt-concretion” toughen achieve posthealing 23 megapascals 95 minutes at temperature, near 100% efficiency. Leveraging tunable rate, hydrogel be tailored reparable wear-resistant material damping device.
