Abstract: Efectis Nederland is developing a mobile furnace, which is capable of determining the concrete spalling sensitivity of existing concrete tunnel linings. The aim of this mobile furnace is to qualify and quantify the spalling sensitivity of the concrete under typical tunnel fire loads, such as the RWS fire curve.
This paper describes the minimum requirements of a mobile furnace based on the fundamental background of the phenomenon of concrete spalling. Furthermore, the design of the mobile furnace is shown in combination with the spalling results achieved with different concrete mixes. In addition a calculation is shown which compares the internal concrete temperatures achieved with the mobile furnace and with the RWS fire curve.
