Abstract: Described are compositions and methods for controlled strength development in a hydratable cementitious material, and more particularly to the use of polymerizable monomer components, which are initiated and activated by a redox pair which are mixed in controlled fashion, for enhancing non-hydration strength within the matrix of the plastic hydratable cementitious material before setting of the cementitious material begins. Exemplary applications include minimizing pressures on formwork for high fluid ready-mix applications, enhancing support and bonding properties for integrated concrete slab work and other sequential applications, or facilitating speedy 3D printing applications, among other unique possibilities.

Abstract: 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 R1, R2, and R3 are provided herein.

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.
