Product Description
Sika Control 40 is a shrinkage-reducing admixture used to produce high performance concrete with greatly reduced drying shrinkage.
USES:
- In premixed and precast concrete elements to reduce the drying shrinkage of the concrete
- In thin bonded topping slabs, to minimize the difference in shrinkage between the new topping and the existing substrate
- In concrete elements which are restrained against shrinkage
- For durable concrete in marine environments
- For watertight concrete in reservoirs, sewage treatment plants, dams.
CHARACTERISTICS / ADVANTAGES
- Reduced drying shrinkage
- Reduction in the potential for drying shrinkage cracking
- Reduces the potential for slab curling
- Substantially reduces the occurrence of drying shrinkage cracks and therefore reduces permeability, resulting in improved concrete durability.
