Abstract: A method of making a cement composition, comprising grinding a cement clinker and a strength-enhancing agent, thereby producing a hydraulic cementitious powder, wherein the strength-enhancing agent is present in the hydraulic cementitious powder in an amount of from 0.001% to 0.09% based on dry weight of the hydraulic cementitious powder. The strength-enhancing agent is a compound represented by the following structural formula (I). The definitions of variables R1, R2, and R3 as well as R10, R20, and R30 are provided herein.

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 Fe203 content of greater than one percent (1%). Also disclosed are exemplary additives and methods for enhancing strength of cement and/or limestone compositions.

Abstract: A method of forming a cement composition. The method comprises adding to a hydraulic cementitious material a first strength-enhancing agent and a second strength-enhancing agent, wherein the content of total alkali (Na2O equivalent) in the hydraulic cementitious material is less than or equal to 0.7% by weight of the cementitious material. The first strength-enhancing agent includes a compound represented by structural formula (I): and the second strength-enhancing agent is sodium sulfate, potassium sulfate, or a mixture thereof. The example values of the variables in structural formula (I) and the example amounts of the first and second strength-enhancing agents being added are defined 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: 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: (I), (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: 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.
