摘要：
A cementitious composition is provided comprising a hydraulic cementitious material, iron chloride and sufficient water to form a pumpable slurry. The iron chloride predictably enhances the rheology and performance of the composition. Methods of cementing subterranean wells are accomplished by mixing together the hydraulic cementitious material, iron chloride and sufficient water to form a pumpable slurry; pumping the slurry to a selected location within the wellbore; and then allowing the slurry to solidify within the well.
