<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic mortar which provides excellent flow performance in a short period of time when a hydraulic composition is kneaded with water, having excellent material separation resistance, small temperature dependency of flow performance of prepared hydraulic mortar (slurry), free from the material separation even when the prepared hydraulic mortar is forcibly sent by a slurry pump to a distant narrow operation place through a slurry hose and having excellent filling property. <P>SOLUTION: The hydraulic composition contains a hydraulic component and inorganic fine powder, wherein the inorganic fine powder has 4,000-15,000 cm<SP>2</SP>/g Blaine specific surface area,≤10.0μm average particle diameter, an average circularity of 0.915-1.000 and 25-45 mass% inorganic fine powder per 100 mass% in total of the hydraulic component and the inorganic fine powder. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
