Beschreibung
Zusammenfassung:	The present invention provides improved well cement compositions useful for performing a variety of cementing applications in subterranean formations and particularly for cementing in subterranean zones having a temperature of about 65 ~F or less. A cement composition of this invention basically comprises a hydraulic cement, an effective amount of an iron compound selected from the group of ferric chloride, ferrous chloride or mixtures thereof to reduce the transition time of the composition, and sufficient water to form a slurry.
