- W125029808 abstract "The authors report results of a study of the use of one slag from the production of nonferrous metals to obtain slag-alkali cements. The study was conducted on slag from a nickel plant. As the liquid component they used solutions of sodium metasilicate, an alkali-soda melt, and sodium silicate of different densities. Since the given slag has a considerable content of SiO/sub 2/ and Al/sub 2/O/sub 3/, its structure contains siloxane (-O-Si-O-Si-O-) and alumooxane (-O-Al-O-) bonds. Thus, the hydration of such glass is determined by the rupture of these bonds as a result of the polarizing action of OH/sup -/ ions, and the characteristics of the cement stone are determined by the type and concentration of the alkali component. The study showed that it is possible to obtain high-strength cements based on nickel slags in combination with different alkaline components. Meanwhile, the activity of the cements can be increased by introducing certain additions such as Portland cement clinker and granulated blast-furnace slag. The use of soluble silicate salts as the liquid component is more promising, these salts producing an alkaline medium in solution. Hydrothermal processing is the best hardening regime." @default.
