Abstract

3D concrete printing gains great attention in recent years because it is labor-saving and free of formwork. The workability of printable concrete is of vital importance because it would change during 3D printing process. The printable concrete should be easy to convey in pipelines and well set in a short period of time after extrusion. The paper simulates the process of mixing and extrusion of printable concrete, with the means of CFD approach. Mixing processes are modelled on a predefined concrete mixture. The rheological behavior of the fresh mixture is expected to be given. For modelling extrusion flow of pumped fresh concrete is supposed through Archimedes auger. Where liquid Flash Setting Admixture (FSA) in liquid state is merged in. Simulating the distribution of liquid FSA aims at finding the way to inject it uniformly before printing concrete out of jet head. This study could provide hints to the design of printing schedule.
