On the Manufacture and Testing of Portland Cement
Portland cement, as is well known, consists of a chemical combination of lime, silica, and alumina with iron in certain well-defined proportions, together with alkalies, magnesia, etc., which enter, in a minor and less essential degree, into its composition. The magnesia, alkalies and sulphuric anhydride, which are found in small varying quantities in nearly every cement, affect its properties in a minor degree, in accordance with the proportions which they bear to each other, and to the whole. The difference between a hydraulic lime and a Portland cement is that in its composition hydraulic lime contains a larger percentage of lime than a Portland cement, and consequently its nature is such that it requires hydrating before use, whether that hydration be effected by grinding or slacking it with water, whereas Portland cement is fit for use without previous hydration; this difference being due not only to the difference in composition, but also to the degree to which calcination is carried.
