Abstract

Interest in 3D construction method has been increasing rapidly in recent years due to its advantages compared to conventional method of reinforced concrete building. The fresh state rheological properties (viscosity, yield stress, thixotropy etc.) of mixtures composed via "layer-by-layer" forming technique gain importance in 3D construction. The influence of fresh state rheological properties on pumpability, extrudability and buildability have been comprehensively evaluated based on recent literature. The role of material ingredients and mixture proportions on the rheological behavior of extrusion mortar is discussed and finally their influence on 3D printing performance is classified.
