Blast-furnace slag is used in the production of cement or cementitious materials in two basic ways: (a) as a raw material for the manufacture of Portland cement, and (b) glassy slag ground and combined with hydrated lime, gypsum or anhydrite, Portland cement, etc., where the slag is utilized for its inherent cementitious properties.

Supplementary Cementitious Material

Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated
