Abstract
A hydraulic composition of the present invention includes (A) 100 parts by weight of cement having a Blaine specific surface area of 2,500 to 5,000 cm.sup.2/g, (B) 10 to 40 parts by weight of fine particles having a BET specific surface area of 5 to 25 m.sup.2/g, and (C) 15 to 55 parts by weight of inorganic particles having a Blaine specific surface area which is 2,500 to 30,000 cm.sup.2/g and which is larger than that of the cement. The inorganic particles (C) may comprise 10 to 50 parts by weight of inorganic particles (C1) having a Blaine specific surface area of 5,000 to 30,000 cm.sup.2/g and 5 to 35 parts by weight of inorganic particles (C2) having a Blaine specific surface area of 2,500 to 5,000 cm.sup.2/g.
