Resumen:
The objective was to know the fire performance of wooden panels (Pinus radiata) impregnated with silica nanoparticles in several silica/alkali molar ratio solutions. Two series of impregnated panels were prepared with diverse penetrations and retentions: after drying/curing at laboratory conditions until reaching constant weight and after finishing this stage with prior distiller water immersion for seven days and a later air exposition for attaining moisture balance. Panels were tested in a limiting oxygen chamber and in a two-foot tunnel. Some results displayed a high fire retardant efficiency.
