Modelling explosive spalling and stress induced thermal strains of HPC exposed to high temperature
Institute for Construction Materials, University of Stuttgart, Germany
Permeability of concrete without and with polypropylene fibres is experimentally measured at temperatures up to 300 °C by employing a new test setup. To investigate explosive spalling of concrete cover numerical modelling is carried out using coupled Thermo-Hygro-Mechanical model oriented towards multi-scale modelling approach. Load induced thermal strains are investigated at meso-scale and it is found that the most part of these strains can be captured by a meso-scale model.
