Abstract: A ready-mixed composition, which sets when mixed with an activator for the reaction of calcined gypsum with water to form set gypsum, is disclosed. The composition comprises water and calcined gypsum in a weight ratio of water to calcined gypsum of from about 0.15 to about 0.5, as well as a set preventer comprising a polyacrylic acid and/or a salt thereof. The composition has a viscosity of from about 5,000 centipoise to about 48,000 centipoise. Also disclosed is a kit that comprises separately packaged components. One of the components is a composition comprising calcined gypsum and a polyacrylic acid and/or a salt thereof, and, optionally, water. Another component of the kit comprises an activator which, when mixed with the composition, permits the composition to set.

Abstract: The present invention provides a setting solution for calcium phosphate cement as well as a calcium phosphate cement composition. The setting solution does not cause disintegration of the composition when the composition is used immediately after preparation. The content of the pectin in the setting solution is 0.5-10% by weight per 100% by weight of the solution. The setting solution has a pH of 3-5, and a viscosity of not more than 200 dPa.multidot.s. The calcium phosphate may be selected from the group consisting of tetracalcium phosphate, calcium hydrogen phosphate, tricalcium .alpha.-phosphate, tricalcium .beta.-phosphate, and hydroxyapatite.

Abstract: A method of forming complex shapes from soft solvent-containing batches and maintaining the integrity of such formed bodies. The formed bodies are made self-supporting immediately after forming or soon thereafter by contacting the shaped body with a drying or hardening liquid in which the solvent is soluble. A method is also disclosed for simultaneously drying a formed body and creating or increasing the porosity of the body by adding solid particles which are soluble in the drying liquid.
