Air Entrainer
ConTec AE-80 is a liquid air-entraining admixture used to provide a suitable air-void system in concrete products. It is based on a high grade saponified rosin chemically similar to vinsol-based products. Concrete durability research has established that proper air entrainment can reduce the effect of freeze thaw cycles in hardened concrete.
Features & Benefits
- Improves workability and plasticity
- Helps reduce bleeding, segregation and shrinkage in concrete
- Improves resistance to freeze thaw cycles
- Improves water permeability
- Greatly improves the properties of precast concrete when used in conjunction with SR-550
Applications
ConTec AE-80 may be used wherever the need for air-entrainment is required by specification. It meets ASTM C 260 requirements designed for use in low slump precast products and is effective and compatible with other admixtures in concrete. AE-80 can be useful in production of “Slump Block”.

TECHNICAL INFORMATION
ConTec AE-80 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 485 lb (220 kg) and 265 gallon (1003 L) totes weighing 2,380 lb (1,079 kg).
ConTec AE-80 can be stored over a wide range of temperatures but should not be allowed to freeze. Should AE-80 freeze, allow complete thawing before mixing by mechanical means. AE-80 has a minimum shelf life of 12 months. With proper storage conditions the shelf life can be greatly extended.
The addition rates for AE-80 will very depending on the amount of air needed for a given job condition. The components of mix design along with temperature are typical factors that effect the amount of AE-required. Consult you ICT representative for assistance.
