Fire Resistance of Wood Impregnated with Soluble Alkaline Silicates

[摘要] The aim of this paper is todetermine the fire performance of woodpanels (Araucaria angustifolia)impregnated with soluble alkalinesilicates. Commercial silicates basedon sodium and potassium with 2.5/1.0and 3.0/1.0 silica/alkali molar ratioswere selected; solutions and glasseswere previously characterized.Experimental panels were tested in alimiting oxygen chamber and in a two-foot tunnel.Results displayed a highfire-retardant efficiency using somesoluble silicates.
