蓄熱材の製造方法及び水硬性組成物

<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an inorganic matter-deposited heat storage material simply and inexpensively, without discharging a harmful matter, that permits controlling a temperature rise upon setting a hydraulic composition and being uniformly mixed with the hydraulic composition. <P>SOLUTION: This inorganic matter-deposited heat storage material of an average particle diameter of 5-100 μm, in which a water-insoluble inorganic fine particle is melt fixed on a surface of a latent heat storage material, is manufactured by way of mixing the latent heat storage material containing at least a ester-structural compound of a melting point of 40-80°C with the water-insoluble inorganic fine particle, at a temperature higher than a melting temperature of the latent heat storage material in presence of water. <P>COPYRIGHT: (C)2009,JPO&INPIT
