<p>Hydraulic composition which comprises 100 parts by weight of a cement having a Blaine specific surface area of 2,500 to 5,000 cm 2>/g, 10 to 40 parts by weight of fine particles having a BET specific surface area of 5 to 25 m 2>/g and 15 to 55 parts by weight of inorganic particles having a specific surface area which is 2,500 to 30,000 cm 2>/g and greater than that of cement, where the inorganic particles preferably comprise 10 to 50 parts by weight of inorganic particle having a Blaine specific surface area of 5,000 to 30,000 cm 2>/g and 5 to 35 parts by weight of inorganic particles having a Blaine specific surface area of 2,500 to 5,000 cm 2>/g. The hydraulic composition exhibits self-compacting property and is greatly excellent in workability before hardening.</p> |
