EARLY STRENGTH ENHANCEMENT OF CEMENTS

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 R.sup.1, R.sup.2, and R.sup.3 as well as R.sup.10, R.sup.20, and R.sup.30 are provided herein.
