Slag Cement

 

the common name for various cements produced by crushing pellets of blast-furnace slags together with activator additives (lime, construction-grade gypsum, and anhydrite) or by mixing the components after they have been ground separately. A distinction is made between lime-slag cement, with a content of 10–30 percent lime (by weight) and up to 5 percent gypsum, and sulfate-slag cement, with 15–20 percent gypsum or anhydrite and up to 5 percent portland cement or up to 2 percent lime. Slag cement is used in the production of mortars and concretes intended primarily for underground and underwater structures. Lime-slag cement is most suitable for the production of autoclave materials and articles.
