    摘要： A method of servicing a wellbore comprising contacting a metal oxide, a soluble chloride or phosphate salt, water, and a liquid retarder to form a cement composition via a continuous process, wherein the liquid retarder is an aqueous solution having a concentration of less than about 25 w/v %, placing the cement composition into the wellbore, and allowing the cement composition to set. A method of servicing a wellbore comprising (a) contacting an aqueous solution with a soluble salt to form a salt solution, (b) contacting an aqueous solution with a solid retarder to form a liquid retarder wherein the liquid retarder has concentration of less than about 25 w/v %, (c) contacting water, the salt solution, and the liquid retarder to form a mixture, (d) contacting the mixture with a metal oxide to form a cement slurry, wherein the cement slurry is produced with an output rate of from about 0.5 barrels per minute to about 20 barrels per minute, (e) placing the cement slurry into the wellbore, and (f) allowing the cement slurry to set.
