摘要：介绍了3D打印混凝土的特点与前景，综述了挤出型工艺的3D打印混凝土的压、拉、折、剪基本力学性能以及增强措施。研究表明：打印层在喷嘴的挤压作用下密实度有所提高，但同时层间易形成薄弱界面，造成性能的各向异性，通过调整胶凝材料、掺入纤维、优化工艺、水浴养护、布筋等措施能有效改善。此外，提出了还需进一步研究的问题。 Abstract: The characteristics and developing trend of 3D printed concrete technique are introduced. The mechanical properties including compression, tension, bending, shear and reinforcement measures of the 3D printed concrete are reviewed. The researches show the compactness of 3D printing layer is improved under the extrusion effect of nozzle, but there are obvious weak interface between the layers, leading to a great anisotropy. However, it can be effectively improved by adjusting the material composition, optimizing the processing manner, adopting special cured methods and steel reinforcement. In addition, the problems required for further research are put forword.
