SikaControl® AER-200 P
SikaControl® AER-200 P has been designed and formulated to deliberately introduce air into mortar or concrete in the form of evenly sized and uniformly distributed micro air voids.
- Improvement of the freeze/thaw resistance
- High robstness in changes of aggregates
- No influence of mixing time on airentrainment
Usage
SikaControl® AER-200 P has been specifically formulated for use in concrete and dry mortar production. SikaControl® AER-200 P significantly improves the freeze/thaw resistance and therefore the durability of concrete and mortar in outdoor use. It is recommended that the use of air-entraining admixtures be considered for conrete and mortar in applications such as:- Shot concrete
- Dams, reservoirs
- Airport runways, hardstands
- Cementitious mortars outdoor use
- Screeds and grouts for shrinkage control
Advantages
Creation of air voids with SikaControl® AER-200 P is based on a chemical reaction (active air-entrainer).The following advantages can be achieved using SikaControl® AER-200 P:
- Improvement of the freeze/thaw resistance and durability of the concrete
- Increased air void stability in concrete
- High robstness in changes of aggregates
- No influence of mixing time and mixing energy on air-entrainment
- Suitable for all type of blended cement
- Reduced early shrinkage
- Pore size mainly < 0,3 mm

Concreting guidance
The standard rules of good concreting practice, concerning production and placing, are to be followed.
Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components.
Fresh concrete must be cured properly and curing applied as early as possible. Compatibility information available on request.
Application
Dispensing
The dry mortar, containing SikaControl® AER-200 P, should be thoroughly mixed in a forced action mixer and accurately dosed with suitable calibrated equipment.
In concrete application, SikaControl® AER-200 P is added at the time of batching to the concrete. Depending on the operation it is either added in a soluable bag or with a powder dispenser into the concrete mixer. Or add SikaControl® AER-200 P to the fine and coarse aggregate. Time between adding SikaControl® AER-200 P on moist aggregates and adding cement and gauging / mixing water shouldn't exceed 30 seconds. The w/b-ratio and consistency control remains the responsibility of the concrete producer.
Recommended dosage
0.2 – 0,4 % on cement weight as shrinkage compensator
0,4 - 1,5 % on cement weight as air-entrainer
