Sika® Ae 200

AIR ENTRAINING ADMIXTURE FOR CONCRETE

Sika air entraining admixtures have been designed and formulated to deliberately form evenly sized and uniformly distributed micro bubbles

  • Air entrainment considerably reduces the effect of freeze / thaw cycles caused by frost
  • Improved durability of concrete exposed to tidal movements
  • Improves the workability and reduces bleeding of mixes with harsh sands and aggregates - advantage of increased workability can be taken to reduce mixing water without reducing handling properties
  • Easier and quicker mixing of concrete in agitator trucks
  • Concrete in transit and placement is more cohesive and will segregate less
  • Concrete becomes easier to place, resulting in less vibration and work effort to achieve proper compaction

Usage

The use of Sika air entraining admixtures significantly improves the workability and durability of concrete. The cohesion is also increased, thus
reducing the risk of segregation, and bleed water movement is reduced. It is recommended that the use of air entraining admixtures be considered for concrete in applications such as:
  • Most forms of low to medium strength concrete
  • Dams, reservoirs
  • Airport runways, hardstands
  • Roading, pavements, footpaths, driveways
  • Slabs and walls

Application

Application Information

Dispensing

Sika® Ae 200 is added directly into the mixing water prior to addition to the aggregates. Do not add to the dry cement or aggregates. Regular tests on the entrained air content should be undertaken with an air meter. If necessary the dosage may need to be adjusted to keep the entrained air content within the required limits.

Compatibility

Sika® Ae 200 is compatibile with other Sika admixtures - after consultation with Sika Technical Dept. Always add separately, do not premix.
Consumption

Recommended Dosage

Typical dosage: 50 - 200 mls/100 kg of cement. Exact dosage rates are determined by air meter tests on trial mixes.
