SikaControl®-20 P VN

SHRINKAGE REDUCING AND COMPENSATING ADMIXTURE

SikaControl®-20 P VN is a shrinkage-reducing and compensating admixture. The effect of the dual-mechanism to control shrinkage allows to produce high-performance concrete with greatly reduced potential for drying shrinkage, cracking and curling.

▪ Controlled expansion mechanism for producing a volume stable concrete.
▪ Reduces curling and allows for increased joint spacing.
▪ Reduces porosity and permeability, resulting in improved concrete durability.
▪ Reduces contraction forces induced from drying shrinkage thus minimizing risks of long-term and unsollicited cracks formation.

Usage

SikaControl®-20 P VN can be used in any type of ready mix concrete or precast/prestressed concrete, grout, mortar or any other cementitious mixes. Some of the applications of SikaControl®-20 P VN may include:
▪ Concrete floors, to compensate for drying shrinkage cracking, control curling and increased joint spacing.
▪ 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 bridge decks and parking structures.
▪ For durable concrete in marine environments.
▪ For watertight concrete in reservoirs, sewage treatment plants, and dams.

Advantages

▪ Controlled expansion mechanism for producing a volume stable concrete.
▪ Reduces curling and allows for increased joint spacing.
▪ Reduces porosity and permeability, resulting in improved concrete durability.
▪ Reduces contraction forces induced from drying shrinkage thus minimizing risks of long-term and unsollicited cracks formation.

Technical Information

Concreting Guidance

The standard rules of good concreting practice, concerning production and placing, are to be followed.
Laboratory trials shall 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

▪ Not following proper curing practices will lead in a decrease of efficiency of the admixture.
▪ SikaControl®-20 P VN will provide best results by using wet curing methods

Application

Application Information

Compatibility

SikaControl®-20 P VN is compatible with commonly-used SCMs and other Sika® admixtures.
Do not premix with other admixtures
Always conduct trials before combining products in specific mixes and contact
our Technical Service Department for information and advice about any specific combinations

DISPENSING

SikaControl®-20 P VN can be added to the concrete either along with the other powder components or after all the other ingredients are added to the concrete mixer or mixer truck.
If it is added after all the other ingredients, adequate mixing should be ensured.
