Multiplast AirEnt
Multiplast AirEnt air entraining admixture is surface active chemicals which cause small stable bubbles of air to beformed uniformly through a concrete mix. The bubbles are mostly below 1 mm diameter with a highproportion being below 0.3 mm. The main reason for using Multiplast AirEnt is to improve the freeze thaw and scaling resistance andhence the service life of concrete. The improved cohesion and compaction can also enhance the quality and life of concrete structures. Multiplast AirEnt is used for durable concrete exposed to thermal fluctuations around freezing point (0°C); lean concrete (cement content less than 250 kg/m³) with a low fine sand content for pumping; concrete with lightweight aggregates to improve the homogeneity, workability and application of the mix.
