Ground Granulated Blast Furnace Slag - an overview ...

Slag. 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 ...
