Sika® Aer TH

Air Entraining Concrete Admixture

Sika® Aer TH A ready to use highly concentrated air entraining concrete admixture.Its efficiency is based upon the entrainment into the mix of a high number of correctly sized and evenly distributed air pores.

Sika® Aer TH provides the following properties:
  • Increased frost resistance
  • Improved workability
  • Improved durability
  • Increased cohesion reducing the risk of segregation
  • Reduced water content without loss of workability
  • Unaffected setting time even when overdosed

Application

Application Information

Dispensing

Sika® Aer TH is added directly to the mixing water prior to its addition to the aggregates.
Consumption

Recommended dosage

30-150 cc. per 100 kg. of cement weight. Exact dosage rates are determined by air meter tests in trial mixes. Factors affecting air contents, include:type, grading and proportion of sand, cement and aggregates. Cement content per cubic metre. Type and fineness of cement. Water cement ratio and temperature.
In certain cases therefore, it may be necessary to increase the 150 cc dosage rate. Air meter tests should be taken consistently and adjustments made to the dosage rate in order to completely control the amount of air entrainment,which should be in the range of 3-6%.
