Abstract
Process for maintaining the fluidity of hydraulic cement compositions, characterized in that it comprises the operations of adding to the hydraulic cement composition, over an extended period of time, a non-retarding agent, which does not entrain air, cement disperser, selected of the group consisting of (a) water-soluble salts of condensates, obtained by condensation with formaldehyde, of sulfonates of benzenoid aromatic hydrocarbons, monocyclics or polycyclic melts, having from 1 to 12 benzene rings, said condensates having a molecular weight of at least 1500, and (b) water-soluble salts of polycyclic melted aromatic benzene hydrocarbon sulfonates having from 3 to 13 benzene rings; said agent being added, either continuously, over an extended period of time, or in doses, at intervals of time, spaced over an extended period of time, to maintain the fluidity of the cement composition above a value predetermined throughout the entire extended period of time.
