Slag cement used in the building industry contains blast furnace slag in ground form, clinker, sulfate, and super-liquefier, e.g. naphthalene sulfonate

摘要

Slag cement contains 70-95 weight % blast furnace slag in ground form with more than 4500 Blaine (cm2/g), 0.1-2 wt.% clinker, less than 5 weight % sulfate, and 0.3-1 weight % super-liquefier, e.g. naphthalene sulfonate. Up to half of the blast furnace slag is replaced by aluminosilicates such as fly ash, alumina or marl.
