The present invention provides foamed cement compositions with improved mechanical properties and methods of cementing in subterranean formations, particularly in conjunction with subterranean well operations. The foamed cement compositions comprise carbon fibers, a hydraulic cement material, sufficient water to form a slurry, an expanding additive, and optionally other ingredients including a weighting agent, a retarding or accelerating agent, or the like.
