Air Entraining Concrete Admixture

SikaPaver® AER PC 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
  • SikaPaver® AER PC 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 AER PC required may vary to maintain a specific air content
Dispensing

SikaPaver® AER PC should be dispensed through suitable calibrated dosing equipment.
Restrictions
  • When using SikaPaver® AER PC a suitable mix design is required and local material sources should be evaluated.
  • Due to the significant number of constituent, mix design, manufacture and placing related factors outside Sika’s control, bubble spacing determination should be carried out by the concrete producer to ensure compliance with BS – EN 934-2. Bubble spacing should be completed using the specific concrete constituents/admixture combinations. For further information see CAA Admixture information sheet AIS 16 which is available at www.admixtures.org.uk
  • Support from our Technical Department is recommended
DISPENSING
  • The standard rules of good concreting practice, concerning production as well as placing, are to be followed. Refer to relevant standards. Fresh concrete must be cured properly.
  • SikaPaver® AER PC should not be added to dry cement
  • SikaPaver® AER PC should be added with the mixing water
