Abstract

To increase the resistance of cement to water, a proportion exceeding 3 per cent of cement clinker of ,25 to 2 mm. in diameter is mixed with the finely ground cement. The clinker may be of the same or of a different kind of cement from that comprising the finely ground constituent and the final product may be obtained either by mixing the finely and roughly ground constituents or by grinding so as to obtain a suitable product. The cement, the clinker, or both may be treated with solutions of compounds of alkalies and alkaline-earth metals, for example, sodium or ammonium phosphate, compounds or solutions of fluorine compounds or solutions of oxalic acid or its salts or are subjected to the action of the vapours of the fluorine-containing acids and then dried, more than one of the above substances being used if desired. Fillers such as sand, sandy gravel, ground building sand, powdered stone, pumice stone, tuff, slag, burnt or unburnt marl, bauxite, loam, gravel, stone, trass or kieselguhr, brick and chamotte may be added and these may be treated with one or more of the substances mentioned above if desired, the treatment taking the place of the treatment of the rough-grained clinker. Rapid or too rapid setting is prevented by precipitating, on the clinker or other ingredients, organic or inorganic material which may be capable of swelling, such as colloidal silicic acid (silica gel), colloidal alumina, colloidal silicic acid compounds, for example, calcium silicate, gelatine, glue, albumen, decomposition products of proteins (protalbin), casein, seaweed-glue, tragacanth, agar-agar, &c. On the other hand the setting may be accelerated by treating with solutions of metallic chlorides, alkali, and alkaline-earth lyes, silicic acid and/or aluminium compounds or permanganate. Instead of treating the ingredients with solutions of the substances mentioned above, some of them may be mixed in the dry state before, during or after burning.
