Air Entraining Concrete Admixture

Sika® Aer-46 is a liquid air entraining concrete admixture which is formulated from modified naturally occurring and synthetic surfactants. It meets the requirements of BS EN 934-2.

  • 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
Usage
  • Sika® Aer-46 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

Application Information
Compatibility

Sika®Admixtures:

  • Compatibility information available on request

Cements:

  • All cement combinations
  • Pulverised Fuel Ash (PFA) is a waste product of modern electricity generation. Only use PFA complying with the relevant British Standard in structural concrete. Such material will vary within the parameters laid down in the standard. Eg fineness, carbon content and loss on ignition. As a result, the amount of Sika® Aer-46 required may vary to maintain a specific air content.
Dispensing

Sika® Aer-46 should be dispensed through suitable calibrated dosing equipment.
