Abstract
A cement composition is shown for use in preparing a pumpable slurry capable of setting and developing compressive strength at low temperatures. The cement composition includes a hydraulic cement, gypsum, calcium chloride and a setting time retarding agent. The cement composition also includes an additive blend comprising sodium metasilicate, lime and hydroxyethyl cellulose. The cement slurries of the invention are prepared by adding mixing water to the dry cement composition in an amount ranging from about 8 to about 13 gallons of water per 89 pounds of dry cement composition.
