  • Description
  • Additional information

                 Silica Fume is a high-performance ultrafine chemical powder obtained as a by-product of silicon and ferrosilicon alloy production. Available in White and Gray grades, Silica Fume consists primarily of amorphous silicon dioxide (SiO₂) and is widely used as a pozzolanic material to enhance strength, durability, and chemical resistance in cementitious and industrial applications.

 

  • Applications:

    • Concrete: Used in high-strength, high-performance, and self-compacting concrete, as well as shotcrete for increased density and reduced permeability.
    • Refractory: Improves fluidity and strength in unshaped refractories.
    • Industrial: Used in fertilizers to prevent moisture absorption and in resins for durability.

Key Aspects of Silica Fume:

  • Production & Properties: Produced in electric arc furnaces, silica fume is extremely fine (average diameter 150 nm) with a high specific surface area, often appearing as grey or white powder.
  • Concrete Enhancement:It acts as a highly reactive pozzolan, reacting with calcium hydroxide to form additional binder, which strengthens the matrix and interfacial transition zone.

Lorem ipsum dolor sit amet, cibo mundi ea duo, vim exerci phaedrum. There are many variations of passages of Lorem Ipsum available, but the majority have alteration in some injected or words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrang hidden in the middle of text.

It has survived not only five centuries, but also the leap into electronic typesetting unchanged. It was popularised in the sheets containing lorem ipsum is simply free text.
