A method for grinding a solid in a vertical roller mill (VRM), comprising grinding at least one solid in the presence of a grinding stabilizing additive, wherein the grinding stabilizing additive comprises an alkanol amino acid compound or a disodium or dipotassium salt thereof having the structural formula (I): The definitions of variables R, R, and Rare provided herein.

Grinding stabilizing additive for vertical roller mills

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 (NaO 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): andthe 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.
