A methodology is proposed for the characterization of
fire resistive materials with respect to thermal
performance models. Typically in these models, materials
are characterized by their densities, heat capacities,
thermal conductivities, and any enthalpies (of reaction
or phase changes). For true performance modelling, these
thermophysical properties need to be determined as a
function of temperature for a wide temperature range
from room temperature to over 1000DG C. Here, a combined
experimental/theoretical/modelling approach is proposed
for providing these critical input parameters.
Particularly, the relationship between the
three-dimensional microstructure of the fire resistive
materials and their thermal conductivities is
