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.Read moreRead less

This project aims to investigate the electro-mechanical behaviours of carbon nanotube reinforced polymer composite structures. Such structures demonstrate considerable potential in structural health monitoring and strengthening due to their unique electro-mechanical behaviours. However, the electro-mechanical behaviours of these composites remain unclear due to the multiscale nature of the problems and the constraint of current techniques to capture nanoscale features that underpin the macroscopic behaviours. This project aims to investigate the electro-mechanical behaviours of these composites and their structures via atomistic simulation and continuum mechanics modelling. The outcomes are intended to enhance the application of these multifunctional composites and improve the performances and sustainability of engineering structures.Read moreRead less
