ABSTRACT A dry cement composition for use in preparing a pumpable slurry capable of setting and developing good compressive strength at low temperatures. The composition includes Portland cement, gypsum cement, calcium chloride as a freezing point depressant, and a setting time retarding agent. Also, a pumpable slurry including components of the foregoing dry composition and water for cementing pipe, such as well casing, in well drilled through low temperature earth formations. Further, a process for cementing such pipe in a well which penetrates a low temperature earth formation involving depositing such slurry in the space between the pipe and the formation, and thereafter allowing the slurry to set. Still further, a process of preparing the foregoing slurry wherein the freezing point depressant and the setting time retarding agent are dissolved in at least a portion of the water for the slurry prior go mixing the water with Portland cement and gypsum cement to form the slurry.
