摘要： A synthetic slag is produced by melting the mineral content of an organic carbon-containing mineral, for example, oil shale or tar sands, with a source of lime such as cement kiln dust. The organic carbon, especially hydrocarbon, content of the mineral is oxidized by oxygen gas, which typically is derived from air or an air/oxygen combination, in an exothermic reaction and the heat generated provides the thermal energy for the reaction between the mineral content and the source of lime. In this way the gaseous products will typically comprise nitrogen, unreacted oxygen, water vapor and carbon dioxide, and heat energy can be readily recovered from the hot off gas products evolving during the combustion reaction. The synthetic slag may be pelletized and employed as lightweight mineral aggregate or milled, or atomized and then milled, to cement fineness to provide slag cement.

摘要： A slag cement mixture and process of making the same is disclosed. The slag cement mixture is composed of cupola slag and portland cement. The cupola slag is optionally ground granulated. One embodiment of the process includes rapidly quenching the slag by submersion into water or by spraying water onto it, and grinding the resulting product to achieve a fineness of at least 6,000 cm2/g. The process also includes the addition of 35% ground granulated cupola slag to portland cement to achieve a stronger and harder cement than portland cement alone.

摘要： A synthetic slag is produced by a high temperature combustion reaction between coal ash having a high carbon content, and a source of lime such as cement kiln dust. The carbon content of the coal ash is oxidized by oxygen gas, which typically is derived from air or an air/oxygen combination in an exothermic reaction and the heat generated is exploited in the melting process. In this way the gaseous products will typically comprise nitrogen, unreacted oxygen and carbon dioxide, and heat energy can be readily recovered from the hot off gas products evolving during the combustion reaction. The synthetic slag may be pelletized and employed as lightweight mineral aggregate or milled to cement fineness to provide slag cement.

摘要： A method for the production of cement clinker comprises the introduction of vitrified slag into the feedstock stream prior to the clinkering zone. The addition of vitrified slag can increase the clinker output rates and/or reduce the energy requirements for maintaining the kiln temperatures. In one embodiment, the vitrified slag is a vitrified blast furnace slag.

摘要： Storable compositions and slurries for cementing oil and gas wells are described which comprise blast-furnace slag besides other additives which are usual in the cementing technique. The compositions and slurries are insufficiently activated (or are activated immediately before introducing them into the well), so that they can be stored for at least 72 hours (alternatively they may be stored indefinitely) without the setting of the composition and dispense with the addition of activation inhibitors. The use of the compositions and slurries in the cementing of oil and gas wells is also described.

Blaine and wherein the latently hydraulic blast furnace slag has a glassiness above 93%, contains 34 to 40% SiO2, 34 to 37% CaO and above 9% and previously below 13% Al2O3. The (CaO+MgO)/(Al2O3+SiO2) ratio ranges from 0.88 to 0.98. Preferably the binder contains 0.5 to 5% porcelain cement clinker or porcelain cement. The above conditions can be met by mixing several slags.
