Silica Fume

Category: Specialty

USE

For production of high strength concrete, corrosion-resistant concrete, abrasion-resistant concrete, and low permeability concrete. Used to make sewer and manhole repair products. Reduces rebound in shotcrete application.

ADVANTAGES

  • Lowers concrete permeability.
  • Significantly increases concrete durability.
  • Increases ultimate strength gain.
  • Beneficial in all types of high strength concrete applications.
  • Improves bond strength to steel.
  • Significantly reduces alkali-silica reactivity.
  • Provides excellent resistance to sulfate or seawater attack.
  • Reduces steel corrosion.
  • Improves freeze/thaw durability of concrete.

DESCRIPTION

Fritz-Pak Silica Fume is a finely-divided mineral admixture, available in both uncompacted and compacted forms. It is a pozzolanic material which is composed of highly refined silicon dioxide in the non-crystalline form. Silica Fume will chemically react with the calcium hydroxide released by the hydration of portland cement to form compounds possessing superior cementitious properties. This ultra-fine material will better fill voids between cement particles and result in a very dense concrete with higher compressive strengths and extremely low permeability.

Silica Fume is recommended for all types of concrete where improved concrete performance with reduced permeability is required to reduce the effect of corrosive chemicals, such as deicing salts, on structural steel. Silica Fume is also recommended where higher density and ultimate strengths are desired. Silica Fume does not contain calcium chloride, nitrates, nitrites or other potentially corrosive materials and is compatible with all standard concrete admixtures.

COMPATIBILITY

Silica Fume is compatible with most air-entraining admixtures, calcium chloride and other admixtures. When used with other admixtures, each one must be dispensed separately into the mix.
