The paper deals with the case study of a fire involving a 600 m reinforced concrete roof slab area that was less than two days old at the time of the fire. Little is known about the effect of fire on extremely green concrete in actual structures, hence this paper represents a contribution to the state of know-ledge on this topic. The paper briefly introduces the structural layout and reviews the extent of the damage. The main sectionof the paper deals with material investigations which were carried out to assess the degree of damage to the reinforcing steel and the concrete. Results of the investigation show that the very young concrete was able to withstand the fire with only minor damage.
