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