Abstract/Summary An experimental analysis of the fire behavior of stone wool composites with stainless steel and gypsum plasterboard linings was performed. The focus was to characterize the micro-scale behavior of stone wool, and identify the main processes occurring in stone wool composites when exposed to heat. Thermogravimetric analysis was applied to two different wools with varying densities and binder content in air and nitrogen atmospheres at 5, 10, and 20 K/min. Results show a low percentage of mass loss that could be linked to the low fraction of organic binder contained in the wool. Intermediate-scale composite assemblies were tested using the Heat-Transfer Inducing Rate System (H-TRIS). Specimens were composed of stainless steel-stone wool, and gypsum plasterboard-stone wool. Tests were performed at (1) constant low incident heat flux (7 kW/m), (2) constant high incident heat flux (60 kW/m), and (3) simulated parametric incident heat exposure. The results of these tests help to identify the relevant phenomena that should be taken into account when modelling building assemblies with stone wool cores (i.e. pyrolysis and combustion of the binder, water transport through the cross-section, and burning of paper).
