Silica Fume is typically grey in color and is categorized as a supplementary cementations material. Silica fume consists of very fine particles. It is a high performance, densified product, derived as a by - product used in pre - mixed concrete for enhancing mechanical properties of concrete with special performance requirements, including increased strength, reduced permeability, improved abrasion resistance and increased corrosion resistance. Being a highly reactive pozzolan, silica fume chemically reacts with calcium hydroxide present in the cement paste creating a stronger calcium silica hydrate.

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

The calcined petroleum coke can be further processed in an anode baking oven in order to produce anode coke of the desired shape and physical properties. The anodes are mainly used in the aluminium and steel industry.
