<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic composition from which a large product and a product with excellent durability can be produced even if produced by pressure molding or pressure molding with vibration. <P>SOLUTION: The hydraulic composition contains at least cement, a pozzolan fine powder, fine aggregate and water and can contain an inorganic particle having a Blaine specific surface area of 2,500-30,000 cm<SP>2</SP>/g and having larger Blaine specific surface area than that of the cement. The inorganic particle is comprised of an inorganic particle A having the Blaine specific surface area of 5,000-30,000 cm<SP>2</SP>/g and an inorganic particle B having the Blaine specific surface area of 2,500-5,000 cm<SP>2</SP>/g. The hydraulic composition can contain a water reducing agent, coarse aggregate and at least one or more kinds of fibers selected from a metal fiber, an organic fiber and a carbon fiber. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
