Abstract
The present invention relates to hydraulically bonded cement compositions and methods of manufacture. Hydraulically bonded cement compositions and methods of manufacture include materials prepared by manipulating under pressure powdered hydraulic cement compositions using known or novel powder packing, casting, or expanding techniques, such that air within the powdered hydraulic cement is successfully removed while the cement is formed into a self-supporting near net final position. Thereafter, the formed hydraulic cement article is hydrated without mechanical mixing of the cement and water.
