The fire resistance of a sprayed concrete inner lining for tunnels has been investigated experimentally. During the experiment the cross section, hanging from rods from a supporting system, was exposed to the hydrocarbon fire curve for three hours. The test results show that the insulation and integrity criteria were maintained for the whole test period. As 2kg/m3 or polypropylene fibres were included in the concrete mix only a limited amount of surface spalling was observed. The thermal properties of the tested concrete were measured with the transient plane source method. The thermal properties of the sprayed concrete were shown by experiments to be in the bounds of what is defined in the Eurocode 1992-1-2.
