Hydraulic cements, methods and products

摘要

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.

主权项

1. A non-aqueous, hydraulic cement-forming composition, comprising a non-aqueous mixture of (a) a non-hydrated powder composition comprising at least 50 weight % calcium silicate powder, and one or more components selected from the group consisting of (i) β-tricalcium phosphate (β-TCP), and (ii) calcium sulfate, (b) non-aqueous water-miscible liquid, wherein the weight to volume (g/ml) ratio of the powder composition to the non-aqueous water-miscible liquid is in a range of about 1:1 to about 5:1, and (c) at least one agent effective to increase the radio-opacity of a cement formed from the composition.
