HIGHLY THIXOTROPIC 3D PRINTING CONCRETE AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2019/237970

A1

A highly thixotropic 3D printing concrete and a manufacturing method therefor, the weight percentage of each component calculated per cube of concrete being: 35-40% of cement, 0.1-0.4% of polycarboxylate water-reducing agent, 0.1-0.4% of polypropylene fibre, 1.0-3.0% of special thixotropic agent for 3D printing concrete, and 12.5-14.5% of water, the remainder being sand. The special thixotropic agent for 3D printing concrete is used to prepare a highly thixotropic 3D printing concrete that has good rheological properties, strong foam stabilising capability, pumpability, extrudability, and constructibility, and does not crack during printing, having early strength performance and shortening the 3D printing condensing time, and obvious deformation not occurring after loading multiple layers of coverage.
