A cement additive contains industrial waste and has the effect of inhibiting formation of monosulfate in a hardened cementitious material. The cement additive contains specifically calcium carbonate, gypsum and coal ash and/or blast-furnace slag powder. This enables efficient use of industrial waste, allows inhibiting monosulfate formation in the hardened cementitious material, and allows producing a hardened cementitious material having good durability (sulfate resistance).

109	Macroporous, resorbable and injectible calcium phosphate-based cements (MCPC) for bone repair, augmentation, regeneration, and osteoporosis treatment	US11054623	2005-02-09	US20050199156A1	2005-09-15	Ibrahim Khairoun; Racquel LeGeros; Guy Daculsi; Jean-Michael Bouler; Jerome Guicheux; Olivier Gauthier
A composition and method for producing interconnective macroporous, resorbable and injectable calcium phosphate-based cements (MICPCs). The composition of the invention sets to poorly crystalline apatitic calcium phosphate after mixing a powder component and an aqueous solution. The multiphasic calcium phosphate components in the cement resorb at different rates allowing the timely replacement by new bone. The interconnected macroporosity in the cement allows for vascularization, entrapment of growth factors, cell colonization and tissue ingrowth. This MICPC can be used for dental and medical applications relating to bone repair, augmentation, reconstruction, regeneration, and osteoporosis treatment, and also for drug delivery, and as scaffolds for tissue engineering.
110	Efficient production of landplaster by collecting and classifying gypsum fines	US1142	1997-12-30	US5901912A	1999-05-11	Dennis B. Voorberg
A landplaster production method includes the steps of providing a supply of particulate gypsum material, drying the gypsum material by passing a stream of heated air thereby as the material is rotated, classifying and separating the dried particles into fines and coarse particles, collecting the suspended fines in a collector, passing the coarse particles to a grinder such as a roller mill for reducing the particles, and mixing the reduced particles with the collected fines for processing into landplaster. The elimination of fines from the feed to the grinder results in significantly greater production by increasing the efficiency of the grinder. Further, the dryer is modified to agitate the dried gypsum material so that it may be more easily introduced into the classifier/separator situated adjacent the drier discharge outlet.
111	Treatment of gypsum plaster	US974010	1978-12-28	US4225360A	1980-09-30	Arthur G. T. Ward
The present invention is directed to the treatment of gypsum plaster prepared from gypsum rock having a substantial content of soluble salts wherein the gypsum plaster is rendered more suitable for manufacturing processes such as the production of gypsum board by rapid and intimate mixing with a flow of cold water followed by rapid separation of the bulk of the water on a continuous filtration apparatus. A preferred form of an apparatus is a suction belt filter and it is preferred that the residence time of the wet plaster on the filter does not exceed 15 seconds. The total time elapsing between initial contact with water and recovery from the continuous filter preferably does not exceed 30 seconds. The salt content of the plaster is considerably reduced by this treatment without significant hydration occurring and the treatment is economic because cold water (up to 40.degree. C.) and no retarder or other additives are preferably employed.
112	Process for preparing calcined gypsum and gypsum board	US939624	1978-09-05	US4201595A	1980-05-06	Eugene E. O'Neill
A process for preparing calcined gypsum (stucco) which comprises treating a mass of calcined gypsum by adding, with thorough blending, small portions of water (about 1-10% by weight) to the calcined gypsum, allowing it to heal, and grinding the healed stucco to recapture the rate of strength development and the ultimate strength which are adversely affected by the water addition. The principal advantage provided by the addition of small portions of water is a reduction in water demand which is retained despite the grinding and optional drying of the healed stucco. If the treated calcined gypsum is not used shortly after the healing procedure, it should be dried to provide storage stability. The reduced water demand is particularly useful in gypsum board manufacture.
113	Manufacture of calcium sulphate alpha hemihydrate	US570946	1975-04-22	US4120737A	1978-10-17	John Sorbie Berrie; Graham Edward Woolley
A process for the manufacture of calcium sulphate alpha-hemihydrate which comprises the step of interacting an aqueous solution of calcium chloride and a source of sulphate or bisulphate ions in an aqueous system at a temperature above the calcium sulphate hemihydrate/gypsum transition temperature under the reaction conditions. The preferred reagents are the waste calcium chloride/sodium chloride effluent of the ammonia soda process and sulphuric acid (e.g. impure sulphuric acid effluent) to give hydrochloric acid as a co-product. The preferred reaction temperature is at least 20.degree. C. above the transition temperature (about 70.degree. C), e.g. at 95.degree.-100.degree. C at atmospheric pressure.
