Description
CHRYSO®Air-PL is an air entraining admixture, which enables to form stable microscopic air bubbles in concrete and mortars. The uniform spreading of micro air bubbles entrained in concrete, stabilized & effectively protects concrete from frost / defrost cycles and the action of defrosting salts.
Domains of application
- All cement types
- Concrete exposed to freeze thaw
- Extruded Concrete
- Dams, Reservoirs
- Light Weight Concrete
- Optimization of coarser particle size distribution
Benefits
In fresh concrete, CHRYSO®Air-PL has a plasticizing effect at constant workability. The air bubbles act as fine particles, and increase the workability of the concrete. It helps stabilizing water in the fresh concrete. Therefore, it limits segregation and reduces, even prevents, bleeding. The air bubbles network created reduces the capillarity phenomenon. It avoids compatibility problems between cement/sand/admixtures. It resists extreme thermal variation and frost action. It is beneficial for lightweight concrete applications, improving workability and reducing bleeding tendency. It is useful in reducing the density of light weight concrete blocks , to ensure that blocks meet thermal insulation requirements. It by means of entraining air, generates cost savings for the concrete producer.
