POLYACRYLIC ACID GRINDING AID FOR ENHANCED CEMENT POWDER FLOWABILITY
A method for grinding cement clinker particles, comprising: introducing to a composition comprising dry cement clinker particles, in a ball mill or roller mill, whereby said particles are ground to have a finer average particle size, an aqueous grinding additive composition comprising: from about 0.1 to about 15% by weight of at least one polyacrylic acid or a salt thereof; and water; and grinding the dry composition comprising the cement clinker particles and the aqueous grinding additive composition to produce a cement product having a pack set index (PSI) greater than that obtained when the polyacrylic acid is not present in the grinding additive.
