Why Slag Cement? | SCA
Slag cement is commonly found in ready-mixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. Slag Cement's History. Slag cement use can be traced to the 1700s when the material was combined with lime to make mortars. The first United States production was in 1896.
Slag Cement
Replacing a portion of portland cement with slag cement – typically from 30% to 50% – significantly lowers the environmental impact of concrete. Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse …
