PROBLEM TO BE SOLVED: To provide a hydraulic composition (mortar or concrete) which exhibits a sufficient water preserving property, viscosity and fluidity by adding with a usual quantity of a water reducer even if a high performance water reducer or a high performance AE water reducer is used. SOLUTION: The hydraulic composition has the essential components such as (I) a water soluble polymer with a bunch hydrophobic group, (II) the high performance water reducer or the high performance AE, (III) an inorganic hydraulic powder and (IV) a fine aggregate.
