Abstract

Non-aqueous hydraulic cement compositions comprise a non-aqueous mixture of (a) a non-hydrated powder composition comprising calcium silicate powder or calcium aluminate powder, and (b) non-aqueous water-miscible liquid. Hardened cements are formed from such hydraulic cement compositions, and methods of producing hardened cements, kits, and articles of manufacture employ such hydraulic cement compositions.
