Air Entraining Concrete Admixture Sika® Aer-5 is a liquid air entraining concrete admixture which is formulated from modified naturally occurring and synthetic surfactants.
It has been specially formulated to perform with concretes containing Pulverised Fuel Ash (PFA)
It meets the requirements of BS EN 934-2. - Provides consistent bubble size and spacing
- Improved cohesion
- Improved workability
- Improved rheology
- Reduced permeability
- Reduced bleeding
- Reduced laitance, enhancing the concrete’s resistance to frost attack
- Reduced loss of air from fresh concrete
|
Usage - Sika® Aer-5 promotes the distribution of microscopic air bubbles throughout the cement matrix.
- Applications that require high resistance to freeze/thawing cycles
- Concrete that will be exposed to tidal conditions, splash zones and de icing salts
Advantages - Provides consistent bubble size and spacing
- Improved cohesion
- Improved workability
- Improved rheology
- Reduced permeability
- Reduced bleeding
- Reduced laitance, enhancing the concrete’s resistance to frost attack
- Reduced loss of air from fresh concrete
Packaging 20 litre drum, 200 litre drum, 1000 litre IBC |
Technical Information Specific Advice Freezing Point +1°C Effect on Setting Negligible Effect of Overdosing Increased air content leading to reduced densities and strength

Application Information Dispensing Sika® Aer-5 should be dispensed through suitable calibrated dosing equipment. DISPENSING - The standard rules of good concreting practice, concerning production as well as placing, are to be followed. Refer to relevant standards. Fresh concrete must be cured properly.
- Sika® Aer-5 should not be added to dry cement.
- Sika® Aer-5 should be added with the mixing water.
- When using Sika® Aer-5a suitable mix design is required and local material sources should be evaluated.
- Due to the significant number of constituent, mix design, manufacture and placing related factors outside Sika’s control, bubble spacing determinationnshould be carried out by the concrete producer to ensure compliance withnBS – EN 934-2. Bubble spacing should be completed using the specific concrete constituents/admixture combinations. For further information see CAA Admixture information sheet AIS 16 which is available at www.admixtures.org.uk
- Support from our Technical Department is recommended.
