GGBFS is obtained by quenching molten iron slag (a by-product of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ground granulated blast furnace slag is a latent hydraulic binder forming calcium silicate hydrates (C-S-H) after contact with water. It is a strength-enhancing compound improving the durability of concrete.

Hydraulic cement, which hardens by hydration of the clinker minerals when water is added. Hydraulic cements (such as Portland cement) are made of a mixture of silicates and oxides, the four main mineral phases of the clinker, abbreviated in the cement chemist notation, being: C3S: Alite (3CaO·SiO2), C2S:belite (2CaO·SiO2), C3A:celite (3CaO·Al2O3), C4AF:brownmillerite (4CaO·Al2O3·Fe2O3).

GBFS is a by-product of iron and steelmaking, produced by quenching (rapid cooling) molten iron slag from a blast furnace in water or steam, to form a glassy, granular product. This creates a hydraulic material that is naturally cementitious and high in calcium silicate hydrates (C-S-H), a compound that increases the strength and durability of concrete.

FGD gypsum is produced from gas captured within emission control systems at coal fired electric utilities. It is the by-product of desulphurization of burnt gas with the wet limestone washing method. Main component is calcium sulphate dihydrate (CaSO4·2H2O), and therefore the FGD gypsum is used as a substitution for natural gypsum.

Fly ash is the finely divided residue that results from the combustion of pulverized coal and is transported from the combustion chamber by exhaust gases. Depending upon the source and composition of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coal-bearing rock strata.

Silica fume, also known as micro silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. The main field of application is as pozzolanic material for high performance concrete. Because of its extreme fineness and high silica content, silica fume is a very effective pozzolanic material.
