ConTec AE-80


ConTec AE-80 is a liquid air-entraining admixture used to provide a suitable air-void system in concrete products. AE-80 is based on neutralized vinsol resin technology that is factory premixed into a ready to use solution for accurate dispensing. Concrete durability research has established that proper air entrainment can reduce the effects of freeze thaw cycles in hardened concrete.


ConTec AE-80 may be used wherever the need for air-entraiment is required by specification. AE-80 meets ASTM C 260 requirements designed for use in low slump and precast products. AE-80 is effective and compatible with other admixtures in concrete. AE-80 can be useful in production of “Slump Block”.


ConTec AE-80 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 485 lbs (220 kg) and 265 gallon (1003 L) totes weighing 2380 lbs (1079 kg).

● 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.


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 like of 12 months. With proper storage conditions the shelf life can be greatly extended.


The addition rates for AE-80 will vary depending on the mount 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-80 required. Consult your ICT representative for assistance.
