SikaControl®-179 AER

Air Entraining Concrete Admixture

SikaControl®-179 AER is a ready to use highly concentrated, air entraining concrete admixture which creates ultra-stable air bubbles that are strong, small and closely spaced. Its efficiency is based upon the number of correctly sized and evenly distributed air pores imparted to the concrete. SikaControl®-179 AER is suitable for use in tropical and hot climatic conditions.

SikaControl®-179 AER provides the following properties: ▪ Increased freeze / thaw resistance
▪ Improved workability and plasticity
▪ Improved durability ▪ Greatly improved stability of air entrainment ▪ Reduced segregation and bleeding ▪ Increased resistance to scaling
▪ Increased cohesion 
▪ Reduced water content without loss of workability ▪ Ready to use - solution is at optimum strength for accurate dispensing

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using SikaControl®-179 AER in concrete. Refer to relevant standards. Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Application Information

Compatibility

SikaControl®-179 AER is compatible with concrete containing other admixtures or admixture systems - water-reducers, high-range water reducers, accelerators, retarders, densifiers and water repellents. Increased air contents generally have a detrimental effect on strengths.
This can be adequately catered for by using SikaPlast®, Sika® ViscoCrete®, Sikament® or Plastiment® as water reducer admixture for concrete. It is compatible with sulfate resistant cement. Please consult our Sika Technical Department for any special usage.

Dispensing

As stated in ACI 212 and other publications, when two or more admixtures are used, they must be added to the mix separately (through dispensers or manually) and must not be mixed with each other prior to adding to the concrete mix. For optimum, consistent performance, the air-entraining admixture should be dispensed on damp, fine aggregate. Add SikaControl®-179 AER admixture to the concrete mix using a dispenser designed for air-entraining admixtures; or add manually using a suitable measuring device that ensures accuracy within ±3 % of the required amount.
Consumption

Recommended dosage

0.1–0.6 % by weight of binder. Exact dosage rates are determined by air meter tests in trial mixes. Factors affecting air content 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.
