Abstract: Compositions and methods for grinding inorganic particles, such as cement, cement clinker, limestone, or other inorganic particles, involving a grinding efficiency enhancing additive comprising a crude glycerin byproduct, obtained through the use of heterogeneous catalyst processes in biodiesel fuel production. The molecules generated through the use of such heterogeneous catalytic processes result in a crude glycerin that confers good additive formulation stability, while avoiding or minimizing large quantities of undesirable compounds such as fatty acids, fatty acid esters, and salts.

Abstract: The present invention discloses cementitious compositions which contain hydratable cement, limestone, or mixture thereof, having improved strength properties due to the presence of calcined clay and certain higher alkanolamines, wherein the calcined clay has an Fe2O3 content of greater than one percent (1%). Also disclosed are exemplary additives and methods for enhancing strength of cement and/or limestone compositions.

Abstract: The present invention provides a method and system for manufacturing cement wherein ground particles of cement and calcium sulfate are subjected to infrared sensors, laser sensors, or both, so that emanated, irradiated, transmitted, and/or absorbed energy having wavelengths principally within the range of 700 nanometers to 1 millimeter can be monitored and compared to stored data previously obtained from ground cement and sulfate particles and preferably correlated with stored strength, calorimetric, or other data values, such that adjustments can be made to the mill processing conditions, such as the form or amounts of calcium sulfate (e.g., gypsum, plaster, anhydride), or cement additive levels. The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.

Abstract: 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.

Abstract: Method for grinding a solid in a vertical roller mill (VRM) and a cement composition prepared by the disclosed methods. A method comprises grinding a solid comprising a cement clinker under a water spray in the presence of a grinding stabilizing additive, wherein the grinding stabilizing additive comprises: (i) an alkanol amino acid compound or a disodium or dipotassium salt thereof having the structural formula:




(ii) a glycol; or a mixture of (i) and (ii), wherein the water spray level is reduced by at least 5% compared to a control. Cement compositions prepared by the disclosed methods have the pre-hydration level (Wk) equal to or less than 1.5%. The values and preferred values of R1-3 are disclosed herein.

Abstract: Disclosed are exemplary method and system for manufacturing cement in a vertical roller mill (VRM) using humidity sensor readings. This enables adjustment of operational variables such as material feed, water, grinding additives, air flow, temperature, and their combinations. Exemplary embodiments allow manufacturers to predict and to improve cement properties, such as strength and setting time, by monitoring and managing humidity of air in the VRM and/or its air flow system.

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.
