FORMED BODY OF HYDRAULIC COMPOSITION

PROBLEM TO BE SOLVED: To simultaneously impart mechanical processability and wear resistance by press forming a hydraulic composition comprising a hydraulic powder, a non-hydraulic powder having an average particle size smaller by at least one figure than that of the hydraulic powder and an agent capable of improving processability, and hardening it by being cured so as to form a metal coating or the like on the surface of the cured material. SOLUTION: The hydraulic composition is prepared by incorporating 2 to 18 pts.wt. an agent (vinyl acetate or the like) capable of improving processability into 100 pts.wt. of a mixed powder comprising 50 to 90 wt.% a hydraulic powder (calcium silicate, portland cement or the like, an average particle size is in the range of about 10 to 40 μm, and the plain specific surface area is >= about 2,500 cm2/g) and 10 to 50 wt.% of a non-hydraulic powder (calcium hydroxide or the like) having an average particle size of
