摘要： The Invention is related to increasing of early strength and final strengths of cements classified under EN and ASTM as Portland or CEM cements and also related to all clinker employing cements and to any kinds which employ calcium sulphates for set optimization and is for composing of new cements by only assessing new methods for production and is for composing of new cements by only assessing new methods to formation and inclusion of calcium sulphate resources which are used for set optimization. A new calcium sulphate resource is obtained by employing lower heats and this input is arranged to different dehydration levels at which they can be most efficient for the selected use. These different dehydration levels are called intermediate phases of dehydrate or hemihydrates or called as monohydrate.

摘要： The invention refers to a recovery proceeding which consists in achieving a thermic transfer from slag to a calcium sulphate dihydrate rock, with the maximum dimension of the granules of 20 mm., in a temperature interval of 100-145° C., into the tank of an autoclave, to a bigger pressure than the saturation pressure of the steams, which corresponds to the temperature of the slag-rock mixture in the autoclave, obtaining, after processing, new types of binders. The installation by which the proceeding is achieved is endowed with equipment that consists in a slag pot (s), the inclined slag runner (1), the bunker (2) with feeding and dosing equipment (3), the drain (4), designed to attain, for the raw materials, impact speeds of 4-6 m/s and impact angles of 40-70°, the autoclave with tank (5), evacuation door (6) and lid (7), classic equipment used in the building materials industry. The new types of binders, according to the invention, named high strength hydraulic plaster and much slag-high strength hydraulic plaster, have hydraulic properties and high strength at compression with values which are approximately of 25-40 MN/m2.

摘要： A composition and process for the manufacture thereof for use in a hybrid building material comprising at least in part Syngenite (K2Ca(SO4)2.H2O) and Struvite-K (KMgPO4.6H2O). Specified constituents, including magnesium oxide (MgO), monopotassium phosphate (MKP) and stucco (calcium sulfate hemihydrate) are mixed in predetermined ratios and the reaction proceeds through multiple phases reactions which at times are proceeding simultaneously and in parallel and reaction may even compete with each other for reagents if the Struvite-K reaction is not buffered to slow down the reaction rate). A number of variable factors, such as water temperature, pH mixing times and rates, have been found to affect resultant reaction products. Preferred ratios of chemical constituents and manufacturing parameters, including predetermined and specified ratios of Struvite-K and Syngenite may be provided for specified purposes, optimized in respect of stoichiometry to reduce the combined heat of formation to non-destructive levels.
