Abstract

An experimental program was carried out to investigate the behaviour of high performance concrete (HPC) thin plates in fire for use in sandwich panels. To reveal the influence of moisture two initial moisture contents for wet and dry samples were examined. In addition, two thicknesses were used to disclose the temperature distributions during the test. A non-linear coupled model for time dependent heat and mass transfer in concrete thin plates was used for temperature and pore pressure computations. Results from modelling and tests are compared and discussed. Moisture content was found to be a critical parameter in the spalling process. The calculated pore pressure induced too low tensile stresses in the matrix to trigger failure, suggesting a major role played by thermal stresses
