AEA Plast
Description

AEA Plast is a chloride-free air entraining admixture based on neutralised vinson resin. It is supplied as a translucent to colourless solution which instantly disperses in water. AEA Plast acts at the interface between the mixing water and cement/aggregate particles to produce microscopic air bubbles, which are evenly distributed throughout the concrete. The entrained air enhances durability by providing protection against the rapid temperature changes found in freezing and thawing conditions and with the use of de-icing salts. AEA Plast is an air-entraining admixture for concrete and mortar which creates highly stable micro air bubbles that are strong, small and closely spaced.

Uses
  • To entrain and retain air in concrete
  • Low slump concrete
  • Flowable concrete even having low past content
  • High temperature concrete
  • Concrete with extended working times
  • Lightweight and pre-stressed concrete
  • Imparting workability to lean harsh mixes
  • Reducing bleeding caused by gap grading of aggregates in the concrete materials
    • Advantages
    • The use of AEA Plast to entrain optimum air content in concrete results in the following improvements in concrete quality:
    • Increased freeze/thaw resistance
    • Increased resistance to scaling
    • Improved air-void system in hardened concrete
    • Reduced permeability - increased water tightness
    • Improved plasticity and workability
    • Reduced segregation and bleeding
    • Greatly improved stability of air entrainment
