A non-aqueous hydraulic cement composition comprises a non-aqueous mixture of (a) β-tricalcium phosphate powder, (b) monocalcium phosphate comprising monocalcium phosphate anhydrous (MCPA), monocalcium phosphate monohydrate (MCPM), or a combination thereof, and (c) non-aqueous water-miscible liquid, wherein a 0.1 g/ml saturated aqueous solution of the monocalcium phosphate has a pH less than 3.0. Methods of producing a hardened cement, hardened cements, kits, and articles of manufacture employ such compositions.
