Conplast AE300 is a chloride-free air entraining admixture based on neutralised vinsol resin. It is supplied as a brown solution which instantly disperses in water.
Conplast AE300 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.
