HYDRAULIC COMPOSITION FOR CENTRIFUGAL MOLDING
To provide a hydraulic composition for centrifugal molding with low viscosity of discharged sludge, and a method for producing a cured hydraulic composition.SOLUTION: A hydraulic composition for centrifugal molding comprises a following component (A), cement, aggregate, and water, with a ratio of water/cement of 15 mass% or more and 25 mass% or less, and with a content of the component (A) being 1.5 kg or more and 3.0 kg or less in the hydraulic composition for centrifugal molding 1 m3. The component (A) is: a copolymer comprising, as constituent monomers, at least one monomer (A1) selected from a fumaric acid, a (anhydrous) maleic acid, and salts thereof, a monomer (A2) represented by a general formula (A2), and a monomer (A3) represented by a general formula (A3). In the constituent monomers of the copolymer, a content of the monomer (A1) is 1 mass% or more and 30 mass% or less, a content of the monomer (A2) is 1 mass% or more and 20 mass% or less, and a content of the monomer (A3) is 50 mass% or more and 90 mass% or less.SELECTED DRAWING: None
