Sika® Aer Solid
Hollow polymer microspheres for artificial air pores in concrete to increase freeze-thaw resistance
Sika® Aer Solid can be utilised instead of air-entraining agents for the reliable production of mortar and concrete with high resistance to freezing/thawing and de-icing salts.
Sika® Aer Solid are tiny prefabricated air bubbles with elastic plastic envelopment. They work similar to those air pores created by air-entraining agents:
- An expansion possibility for freezing water
- A reduction of the capillary suction effect
- A substitute of fines
- This causes in mortar and concrete:
- A high resistance to freezing/thawing and de-icing salts
- A reduced capillary water absorption
- An improved workability by means of "ball bearing effect"
- Easily obtaining of a high resistance to freezing/thawing and de-icing salts even under difficult conditions
- No rising to the surface even in very flowable concretes
- Low influence on the compressive strength
