摘要
This invention relates to enhancing the compressive strength of cements after 1, 3, 7 and 28 days following hydration and to improving porosity and finished surfaces of the hardened cements and concretes made therefrom. The improved cements are prepared using certain hydroxylamine additives in amounts of up to 0.1% which preferably are added during grinding of the cement in which case the amines further act as grinding aids.
