In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete. Blast furnace slag can also be used to make Ground Granulated Blast-furnace Slag (GGBS) which is used as a cement replacement in concrete.

Granulated phosphorus slag is a latent cementitious material but less reactive than granulated blast-furnace slag at early age due to the lower Al 2 O 3 content and the presence of P 2 O 5 and F. A hydraulic index of phosphorus slag is defined as follows (Shi et al., 2006; RCT 5024-83, 1983):

Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled. Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is hydraulic cement. When slag cement is mixed with water, however, the initial hydration is much slower than portland cement mixed with water; therefore

The introduction of slag in the amount of up to 50% allows to decrease the total heat evolved by the slag cement pastes. However the total heat reduction is much less that the cement clinker substitution: by 27% for the new slag, 35% for the crushed slag and 36% for the old slag, comparing to the reference cement with no additive.

2.1 Granulated 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

Ground Granulated Blast Furnace Slag (GGBFS) GGBFS is a byproduct of steel production similar to ACBFS, but it is rapidly-cooled by water immersion. This rapid cooling produces a glassy, non-crystalline material that, when ground, produces cementatious-sized particles (rather than the aggregate-sized particles of ACBFS).
