Abstract: A hydraulic cement composition is effectively dispersed with use as a dispersion agent of a reaction product obtained by oxidizing and polymerizing a condensate between formaldehyde and a naphthalenesulfonic acid salt or an alkylnaphthalenesulfonic acid salt to have a constitutional unit derived by cutting of the methylene group, that derived by hydroxyzation and condensation polymerization and that derived by the oxidation and the ring-opening of the naphthalene ring.

Abstract: Cement Dispersant The cement dispersant comprises a macromolecular lignosulfonic acid or a salt thereof. It may be a composition which comprises (a) said macromolecular lignosulfonic acid or a salt thereof and (b) a condensate of beta-naphthalenesulfonic acid and formaldehyde or a salt thereof. It prevents the slump loss in the cement composition.
