An admixture that allows air to penetrate and the production of low-density cellular concrete, the formation of fine air cells evenly distributed over the entire concrete substrate, increasing the air content in cellular concrete.

Features

• product in a concentrate of high efficiency
• prevents sendimentation
• cellular concrete made with the addition of this product is very light, yet it is suitable for spreading and leveling on slabs designed for low and medium pressure
• material easy to pump
• reduces the capillarity of concrete as a result of the introduction of the air medium in order to increase frost resistance, while maintaining hardness
• improves the workability of concrete

Application

Concrete resistant to frost, exposed to constant access to water: hydrotechnical concrete, concretes and mortars made in winter conditions, concrete for road and airport surfaces (obligatory in many countries), plastering mortars and external cladding, sprayed concrete.
