Abstract
При способе получения цемента из металлургических шлаков, при котором жидкие шлаки из восстановительных и сталеплавильных процессов, как, например доменные и конвертерные шлаки, перемешиваются друг с другом и смешиваются с известью. На первой стадии охлаждения при температурах свыше 1000°С, предпочтительно свыше 1200°С, охлаждение осуществляется медленнее, чем на второй последующей стадии охлаждения, полученный застывший продукт гранулируется и/или перемалывается, чтобы непосредственно получить цемент с улучшенными гидравлическими свойствами, в частности с повышенной окончательной прочностью.
