Abstract

320,597. Badder, H. C. April 26, 1929. Divided application. Cements, Portland and Roman.-Coloured hydraulic cements are made by fusing a pure base of Portland cement or of aluminous cement, or the like, together with metallic oxides, carbonates or other salts. A small proportion of fluxing material may also be added. The raw materials and colouring matter are very finely ground, for instance to pass a 200 per inch mesh sieve. The fused cement is run into moulds and subsequently ground. Examples of colouring matter are ferrous and ferric oxides, oxides of copper and cobalt, salts of iron, copper, manganese, cobalt and chromium, and earth pigments such as ochre, bole, sepia and brown umber. In some cases a proportion of finely ground metal may be added to overcome the effects of the caustic lime on the colours.
