Concrete mixtures with large content of fly ash as a bi nder were selected for large scale exp eriments whereas cubes were made of cement based mixtures as w ell as of alkali activated fly ash mixtures. The influence on polypropylene fibres, added into half of the specimens, on the fire resistance is also described. Second part of the paper is focused on the numerical modelling of the effect of fire using a simplified numerical approach. Experimental data are used for calibration of the models as well as for the comparison of results. The loading is governed by RWS Curve which assumes 50 cubic meters of petrol or oil fire in the tunnel.
