Abstract
Cement is made from blast-furnace slag by adding thereto, without subsequent burning, (1) anhydrite or gypsum cement, or a mixture thereof, or insoluble anhydrite, or Estrich gypsum, in combination with one or more of the following-chalk (or limestone or marble), dolomite, fluorspar or phosphorite (or calcium superphosphate), or (2) dolomite burned to 500-800 DEG C. combined with insoluble anhydrite or Estrich gypsum with or without the addition of unburned dolomite, fluorspar or phosphorite. In an example granulated slag is ground in a ball mill together with 5 per cent of Estrich gypsum, 2 per cent of chalk and 3 per cent of superphosphate. Other examples are given. Specification 258,727, [Class 22, Cements &c.], is referred to.
