Publication number: 20140312517Abstract: Refrigerated hydraulic cement compositions comprise a mixture of (a) ?-tricalcium phosphate powder, (b) monocalcium phosphate comprising monocalcium phosphate anhydrous (MCPA), monocalcium phosphate monohydrate (MCPM), or a combination thereof, wherein a 0.1 g/ml saturated aqueous solution of the monocalcium phosphate has a pH less than 3.0, (c) non-aqueous water-miscible liquid, and (d) an aqueous hydrating liquid. The aqueous hydrating liquid is included in an amount of about 1-50 volume percent, based on the combined volume of the non-aqueous water-miscible liquid and the aqueous hydration liquid, and the refrigerated hydraulic cement composition is storage stable for greater than one day, without setting. Methods of forming hardened cements in vivo and/or for forming implants for use in vivo employ the hydraulic cement compositions.Type: ApplicationFiled: September 10, 2012Publication date: October 23, 2014Applicant: OSSDSIGN ABInventors: Håkan Engqvist, Jonas Åberg

Publication number: 20140272376Abstract: Disclosed are cementitious product, as well as cementitious slurry, and method of forming the product. To reduce density in the cementitious product, foam is included in the slurry and in the method of forming the product. The slurry includes cementitious particles, water, and air bubbles such as from compressed air. Instead of using detergent chemistry at the gas/water interface of bubbles, the present invention uses a surface modifying agent for the cementitious particles in the slurry. The modified particles act to produce stable foam in the slurry. As an example mode of introduction, the surface modifier can be added (e.g., as solid or solution) directly into a bulk cementitious slurry that forms the product. As another example, the surface modifier can be added in a separate solution with water, air bubbles, and cementitious particles that serve as additive to the main cementitious slurry, where the separate solution is then added to the main cementitious slurry.Type: ApplicationFiled: September 18, 2013Publication date: September 18, 2014Applicant: United States Gypsum CompanyInventors: Naser ALDABAIBEH, Kumar NATESAIYER, Ashish DUBEY
