PURPOSE:To obtain a high-strength hardenable material capable of controlling the hardening reaction by blending a hardenable material containing tetracalcium phosphate powder with an inorganic or an organic hardening modifier and forming a surface coating layer. CONSTITUTION:The hardenable material is obtained by adding and blending an inorganic hardening modifier and/or an organic hardening modifier with a hardenable material containing power, having a surface coating layer and consisting essentially of tetracalcium phosphate. Respective oxides, hydroxides, fluorides, chlorides, carbonates, phosphates, sulfates, silicates, etc., of lithium, sodium, potassium, magnesium, calcium, aluminum, zinc, bismuth or tin are cited as the inorganic hardening modifier used. Collagen, chitosan, tannic acid, ethanol, propylene glycol, etc., are cited as the organic hardening modifier. |
