PURPOSE:To obtain a dispersing agent for an inorganic hydraulic composition having excellent dispersing performances, by copoymerizing acrylic acid with maleic acid, maleic anhydride or fumaric acid. CONSTITUTION:The dispersing agent for an inorganic hydraulic composition, is obtained by copolymerizing acrylic acid with a monomer (a) selected from maleic acid, maleic anhydride or fumaric acid, or copolymerizing a monomer copolymerizable therewith with the monomers. As the monomers copolymerizable with the monomer (a), hydroxyethyl (meth)acrylate, N-vinylpyrroridone, sodium styrene sulfonic acid, etc., are cited. This hydraulic composition is obtained by blending a latently hydraulic material, a super fine powdery material, a curing stimulator, and the dispersing agent. This hydraulic composition can be used in a wide field such as architecture, construction or scenic material, since it has good fluidity property, and is excellent in compression, bending and stretching strength.
