The use of iron blast-furnace slag as a constituent in concrete as an aggregate, a cementitious material, or both is well known. Recent attention has been given to the use of slag cement as a separate cementitious constituent in concrete. This report addresses the use of slag cement as a separate cementitious material added along with portland cement in the production of concrete. This report does not address slags derived from the smelting of materials other than iron ores. The material characteristics described and the recommendations for its use pertain solely to cement ground from granulated iron blast-furnace slag.
