Abstract
3768. Michaelis, W. Feb. 21. Cements.-Relates to cements which differ from Portland cement in that they are very resistant to the action of sea-water, the sulphates in which exert a deleterious influence on the calcium aluminate of Portland cement. In the improved cement, the alumina is replaced by oxide of iron, manganese, or chromium. Finely-divided calcareous stone, especially silicious calcareous marl, or burnt lime is intimately mixed with ground brown hµmatite, calcareous ironstone, bog-iron ore, spathic iron ore, or red haematite. Instead of these ores, a manganiferous oxidized iron ore may be used, or byeproducts, such as spent pyrites or chrome iron ore residues. When the calcareous material is poor in silicious matter, silica is added to the mixture. The mixed materials are burnt at a clinkering or sintering temperature, and are then finely ground. The materials may be mixed in any proportions with those used for Portland cement, or the finished cements may be mixed. The Provisional Specification mentions puddling-furnace slag and finery slag as constituents of the cement.
