HIGH FLOW FIRE RESISTIVE COATING MATERIAL AND FIRE RESISTIVE COATING METHOD MAKING USE THEREOF

PROBLEM TO BE SOLVED: To provide an economical fire resistive coating material without wasting the material and a fire resistive coating method obtaining fire resistance efficiency equal to or higher than fire resistive coating by the conventional spraying method and integration with a fire resisting object and obtaining the fire resistive coating having a uniform thick and smooth surface excellent in workability without making a site dirty. SOLUTION: A form 5 is assembled around a steel frame 1, the fire resistive coating material having high flowability developed for the method is poured inside of the form 5, and it is solidified to form a fire resistive coating layer. The fire resistive coating material is so formed that water is added to a premixed material having inorganic light aggregate such as vermiculite foam, perlite or the like, hydraulic binder such as various cements, etc., and admixture as main ingredients, and the material having high flowability with the extent of 4 to 30 seconds as a J funnel falling time for flowability in the time from direct after the mixing up to the injection is used.
