The project aims to develop a new rheological model for 3D printable concrete for construction. 3D concrete printing is an innovative and promising construction technique, but the main impediment to progress is lack of suitable material technology. In this study, a new stress and time dependent flow model will be formulated and implemented as a computational model. The model will facilitate the study of the effect of different concrete formulations, pumping and printer parameters on the primary printing properties, namely, pumpability, extrudability and buildability. The new model will also enable active control and modification of rheological parameters on-the-fly during large-scale printing, which is not currently possible.

该项目旨在为建筑用3D打印混凝土开发一种新的流变模型。3D混凝土打印是一种创新且有前途的建筑技术，但主要障碍是缺乏合适的材料技术。在这项研究中，一个新的应力和时间相关的流动模型将制定和实施的计算模型。该模型将有助于研究不同的混凝土配方，泵送和打印机参数对主要打印性能，即，可泵性，可挤出性和可构建性的影响。新模型还将在大规模打印过程中对流变参数进行主动控制和修改，这在目前是不可能的。
