Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.

Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve.

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
