Patent ID: 8865791

Claim:
A composition comprising: a solid phase comprising at least one calcium derivative, at least one radioopacifier, and at least one polymer; wherein said at least one calcium derivative is selected from one or more of: calcium silicate, calcium aluminate, tetracalcium aluminoferrite, calcium phosphate, calcium sulfate, calcium oxide, and calcium hydroxide; wherein said at least one radioopacifier is selected from one or more of: bismuth oxide, bismuth carbonate, yttrium, strontium carbonate, strontium phosphate, barium sulfate, tantalum oxide, cerium oxide, tin oxide, a zirconium oxide compound, and a radioopaque glass containing one or more of tantalum, barium, and strontium; wherein said at least one polymer is selected from one or more of: polyvinyl alcohol, polyvinyl-pyrrolidone (PVP), partially hydrolyzed polyvinyl acetate (PVAc), polyacrylic acid (PAA), polymethacrylic acid (PMA), acrylic based polymer, alginate, and non-water soluble polymer; wherein said at least one calcium derivative, said at least one radioopacifier, and said at least one polymer are present in an amount ranging from 30 to 80%, 1 to 50%, and 1 to 20% in weight to the weight of the solid phase; and an aqueous phase comprising water, at least one water-reducing agent, and at least one set accelerator; wherein said at least one water-reducing agent is selected from one or more of: polycarboxylate and a modified polycarboxylate; and wherein said water, said at least one water-reducing agent and said at least one set accelerator are present in an amount respectively ranging from 50 to 85%, 5 to 15% and 10 to 50% in weight of the weight of the liquid phase; and wherein the ratio of solid phase to liquid phase is from 1.0 to 2.5 and, wherein the composition has a compressive strength from about 1 to about 15 MPa after setting.
