SikaFume® SF 100

Densified microsilica

SikaFume® SF 100 is a compacted microsilica mineral admixture, formulated to produce extremely strong and durable concrete. SikaFume® SF 100 is a micro-filler material that physically fills the spaces between cement particles; It drastically decreases permeability and reduces the size and number of capillaries that allow contaminants to enter the matrix.

  • Greater cohesiveness of the mixture.
  • Less exudation.
  • Improved performance.
  • Increase in the service life of the structure.
  • Greater development of mechanical resistance.
  • Greater modulus of elasticity.
  • Lower permeability increasing durability.
  • Greater resistance to sulfate attack.
  • Greater resistance to the alkali-silica reaction.

Product Information

Shelf life

12 months from the date of production

Storage conditions

SikaFume® SF 100 is stored, handled and dosed similar to cement or fly ash. It can be stored in silos when in bulk. The packaged product should be stored in a dry area avoiding moisture.

Total chloride ion content

Does not contain chlorides. SikaFume® SF 100 admixture will not initiate or promote corrosion of reinforcing steel embedded in concrete, in prestressed concrete or concrete placed in galvanized steel roof and floor systems. No calcium chloride or intentionally added chloride-based ingredients have been added in the manufacture of SikaFume® SF 100.

 
System information

System structure

SikaFume® SF 100 is a micro-filler material that physically fills the spaces between cement particles; It drastically decreases permeability and reduces the size and number of capillaries that allow contaminants to enter the matrix. Compared to pozzolan, SikaFume® SF 100 microsilica reacts chemically within the cement matrix to increase the amount of hydrated calcium silicate (CSH gel) that is formed. CSH gel is the adhesion agent that holds the matrix of a cementitious mixture together in its hardened state. Additional CSH gel increases strength and decreases permeability.

Application

Application Information

Compatibility

SikaFume® SF 100 additive can be used with portland cements approved under ASTM, AASHTO or CRD specifications. It is compatible with most concrete admixtures, including all Sika® admixtures. The use of SikaFume® SF 100 is recommended with high range water reducing admixtures, such as the Viscocrete® line, to obtain maximum workability, keeping the water-cement ratio low.

Dispensing

SikaFume® SF 100 is dosed and added in the concrete production plant in a similar way to cement or other cementitious materials such as fly ash. It can be dosed in a central mixer or mixer truck.
Consumption

Recommended dosage

It is recommended to use SikaFume® SF 100 for concrete or wet shotcrete applications in a dosage range of 5% to 15% by weight of cementitious material.
