Slag cement use can be traced to the 1700's when the material was combined with lime to make mortars. The first United States production was in 1896. Until the 1950's, granulated slag was used in the manufacture of blended portland cements, or as raw feedstock to make cement clinker. However, in the 1950's, slag cement became available in ...
