Abstract:
The present invention provides cement grinding additive compositions and methods which allow a PVC-safe, powerful, and robust defoaming agent to be uniformly dispersed throughout a broad concentration range while retaining storage stability even in cases wherein the defoaming agent is highly diluted. Exemplary cement grinding additive compositions comprise at least one amine cement grinding additive; an air detrainer selected from the group consisting of (i) ethoxylated, propoxylated fatty alcohol or alkylphenol, (ii) polyalkoxylated polyalkylene polyamine, or (iii) a mixture thereof.
