SikaControl®-140 AER

Air entraining concrete admixture

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.

SikaControl®-140 AER provides the following properties:
  • Increased frost resistance
  • Resistant to de-icing salts
  • 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

SikaControl®-140 AER is added directly to the mixing water, prior to its addition to the aggregates.
Increased air contents, generally have a detrimental effect on strengths. This can be adequately catered for by using a Plastiment®, SikaPlast® or ViscoCrete® admixture. Please refer to our Technical Services Department.
Consumption

Recommended Dosage

0.03 - 0.15% by weight of cement. 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 0.15% 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%.
