Abstract
In the method of the invention, a storable hydraulically-active cementitious slurry is made and used to cement within subterranean foundations for oil and gas wells. The slurry is made from hydraulically-active, cementitious material suitable for oil field purposes and can be stored until needed. During storage, the slurry remains liquid. The slurry is activated when needed for cementing. After pumping the activated slurry into the wellbore, the set cement has properties acceptable for well cementing.
