Description :

Sika® Aer-5 is a liquid air entraining concrete admixture which is formulated from modified naturally occurring and synthetic surfactants. It has been specially formulated to perform with concretes containing Pulverised Fuel Ash (PFA) It meets the requirements of BS EN 934-2.

Uses :

• Sika® Aer-5 promotes the distribution of microscopic air bubbles throughout the cement matrix.
• Applications that require high resistance to freeze/thawing cycles
• Concrete that will be exposed to tidal conditions, splash zones and de icing salts

Characteristics/Advantges :

• Provides consistent bubble size and spacing
• Improved cohesion
• Improved workability
• Improved rheology
• Reduced permeability
• Reduced bleeding
• Reduced laitance, enhancing the concrete’s resistance to frost attack
• Reduced loss of air from fresh concrete
