Slag Cement Questions Slag Cement Association

Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water, dried and ground to a fine powder. The rapid quenching granulation freezes slag cement in a glassy state and imparts cementitious properties to the product when ground finely.
