<p>A hydraulic composition which comprises (A) 100 parts by weight of a cement having a Blaine specific surface area of 2,500 to 5,000 cm2/g, (B) 10 to 40 parts by weight of fine particles having a BET specific surface area of 5 to 25 m2/g and (C) 15 to 55 parts by weight of inorganic particles having a specific surface area which is 2,500 to 30,000 cm22/g and greater than that of the cement (A), wherein the inorganic particles (C) preperably comprises 10 to 50 parts by weight of inorganic particles A having a Blaine specific surface area of 5,000 to 30,000 cm2/g and 5 to 35 parts by weight of inorganic particles B having a Blaine specific surface area of 2,500 to 5,000 cm2/g. The hydraulic composition exhibits self-compacting property and is greatly excellent in workability before hardening, and also provides a hardened product having excellent mechanical strength.</p> |
