An ab initio approach for thixotropy characterisation of (nanoparticle-infused) 3D printable concrete

This paper presents a novel rheological thixotropy model that specifically appertains to the characterisation of materials that are suitable for 3D printing of concrete (3DPC). The model accounts for both physical and chemical influences on a material’s microstructure, denoted by Rthix (re-flocculation) and Athix (structuration) respectively. Rheological analyses are performed on a reference material with varying superplasticizer (SP) and...
