Sika® Aer Solid

HOLLOW POLYMER MICROSPHERES FOR ARTIFICIAL AIR PORES IN CONCRETE TO INCREASE FREEZE-THAW RESESTANCE

Sika® Aer Solid consists of hollow microspheres with an elasto-plastic surface that are added to a concrete mix to provide artificial air voids instead of using air-entraining admixtures.

  • Additional space for expanding freezing water
  • Reduced suction of capillary pores
  • Substitute for additional fines
  • Additional support in the matrix of mortars and concretes
  • Increased resistance to freeze-thaw and de-icing salts
  • Reduced capillary water absorption
  • Improved workability by means of 'ball bearing effect'
Advantages over conventional air-entraining admixtures:
  • Obtains high resistance to freeze-thaw and de-icing salts, even under difficult consistence or installation requirements/conditions
  • Lower concrete strength reduction

Usage

Creates artificial air pores in concrete to increase the frost and freeze/thaw resistance. Typical structure types:
  • Bridges, roads, water and marine
Concrete applications:
  • High strength concrete with durable performance requirements
  • Very flowable concrete requirements e.g. SCC (Self-Compacting Concrete) where it is often difficult to keep normally air-entrained air voids in suspension
  • Very low or no-slump concrete, where it is difficult to introduce air voids with air entraining agents
  • Shotcrete applications with requirements for high resistance to freeze-thaw and de-icing salts
  • Difficult application conditions e. g. long concrete transportation times or long pumping distances
  • Power floated concrete surface (external parking areas)

Technical Information

Concreting Guidance

The standard rules of good concreting practice, concerning production and placing must be followed.
Laboratory trials must be carried out before concreting on site, especially when using a new mix design or producing new concrete components.
Fresh concrete must be cured properly and curing applied as early as possible.

Specific Advice

Sika® Aer Solid in concrete can be verified by washing out the hollow microspheres according to ASTM C-173/C-173M-01.Testing in a standard air void pot will give incorrect results.

The Roll-A-Meter-value as a part of the required dosage is to be determined in the context of the initial testing. Within the initial testing a CDF-test according to DIN CEN/TS12390-9, Section 7 must be performed.

Application
