ABSTRACT:
Cement compositions with improved corrosion resistance, and methods of using the compositions in a subterranean formation, are provided. The cement composition comprises a high alumina cement, vitrified shale, a soluble phosphate, and water sufficient to form a slurry. Optionally, other additives may be included, such as accelerants, retardants, dispersants, and the like.
