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.
