Abstract:
A method of servicing a wellbore comprising preparing a composition comprising a calcium aluminate cement, water, a polyphosphate, a pozzolan, and a set retarding agent, wherein the set retarding agent comprises an alkali halide and a basic phosphate salt, placing the composition in the wellbore and allowing the composition to set. A composition comprising a calcium aluminate cement in an amount of from about 30 wt. % to about 60 wt. % and a set retarding agent in an amount of from about 0.1 wt. % to about 15 wt. % based upon the total weight of the composition, wherein the set retarding agent comprises an alkali halide and a basic phosphate salt in a ratio of from about 3:1 to about 1:3.
