Abstract
Cements or hydraulic binders may be prepared by adding an aqueous suspension comprising a ground mineral filler and at least one grinding aid agent to a cement or hydraulic binder. The resulting cement or hydraulic binder has very appreciably improved mechanical properties, particularly the property of “strength at young ages.” The grinding aid agent may be a natural or synthetic homopolymer and/or copolymer.
