Current Projects

In this project we develop a coupled simulation approach for the shotcrete process to predict the performance of a specific shotcrete nozzle geometry and the resulting jet dynamics as a function of the additive mixing within the nozzle and during the jet propagation. The model includes multiple components and phases as well as individual grains which are being advected with the mixture. A realistic stress-strain relationship is being developed to recover the correct non-Newtonian behaviour of the mixture including its thixotropic properties. The fully coupled simulation will serve to predict the behaviour of the shotcrete printer to be developed in Institute of Building Materials, Concrete Construction and Fire Safety.
