DILUTION-STABLE CEMENT GRINDING ADDITIVE COMPOSITION
The present invention provides cement grinding additive compositions and methods which allow a powerful, robust defoamer to be uniformly dispersed throughout a broad concentration range while retaining storage stability even in cases wherein the defoamer is highly diluted. Exemplary cement grinding additive compositions comprise at least one amine cement grinding additive; a tri-iso-butylphosphate defoamer; a biopolymer polysaccharide gum selected from the group comprising Diutan, Whelan, Xanthan, or mixtures thereof; and water in the amount of 0.10 to 95.0 percent based on total weight of composition. Methods for manufacturing cement using the cement grinding additive compositions are also described.
