CEMENT COMPOSITIONS COMPRISING HIGH ALUMINA CEMENT AND CEMENT KILN DUST AND METHOD OF USING THEM

摘要

The present invention provides cement compositions that comprise water, high alumina cement, a soluble phosphate, and cement kiln dust. The cement compositions optionally may be foamed with a gas. Methods of cementing also are provided that comprise: providing the cement composition; introducing the cement composition into a location to be cemented; and allowing the cement composition to set therein. The location to be cemented may be above ground or in a subterranean formation.
