    Abstract

    Mineral fiber compositions for spray-applied fire resistive coatings to buildings are factory mixed products consisting of manufactured inorganic fibers and proprietary binders. Air setting, hydraulic setting, and ceramic binders are used singly or in varying combinations and quantities depending on the use for which the product is designated.

    The fibrous materials most commonly used for fireproofing generally range in applied density from 0.2 to 0.6 g/cm3 and range in applied thicknesses from 1.0 to 6.0 cm on decks and up to 8.0 cm on beams and columns. The spraying process is generally performed with a specially designed machine that feeds the dry mineral fiber composition to a spraying nozzle where the fiber mixture is enveloped with water as it is sprayed onto the surface to be protected. Fire resistant characteristics and other important properties such as insulation and acoustics, and resistance to air erosion and corrosion are discussed.
