SikaControl® SC

SHRINKAGE REDUCING AND COMPENSATING ADMIXTURE

SikaControl® SC is a shrinkage compensating admixture used to produce highperformance concrete with greatly reduced potential for drying shrinkage, cracking and curling.

  • Greatly reduced cracking potential related to drying and autogenous shrinkage.
  • Reduced curling and increased joint spacing.
  • Substantially improved impermeability, resulting in improved concrete durability.

Usage

SikaControl® SC can be used in any type of cast-in-place or precast/prestressed concrete, grout, mortar or any other cementitious mixes. Some of the applications of SikaControl® SC 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 mass concrete structures such as mat foundations, dams and other structures requiring large thickness of concrete exceeding 1 m (3 ft).
  • For durable concrete in marine environments.
  • For watertight concrete in reservoirs, sewage treatment plants, and dams.
 

Advantages

  • Greatly reduced cracking potential related to drying and autogenous shrinkage.
  • Reduced curling and increased joint spacing.
  • Substantially improved impermeability, resulting in improved concrete durability.

Application

Application Information

Mixing

SikaControl® SC 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 truck. If it is added after all the other ingredients, adequate mixing should be ensured. The 25 lb repulpable bags are designed to disintegrate through a combination of wetting and grinding the paper during concrete mixing. To maximize product performance proper curing practices should be followed as per ACI 308 or project specifications.

  

Limitations: 

  • Do not introduce dissolvable bags into concrete mixes with low water to cementitious material ratios and smaller size aggregates as these mixes may not develop sufficient mixing energy to fully dissolve the bags. Always determine the capacity of the bags to dissolve by pretesting mix designs and batch sequence.
  • Not following proper curing practices will lead in a decrease of efficiency of the admixture.
  • SikaControl® SC will provide best results by using wet curing methods.
  • The use of a curing and sealing compounds will reduce the efficiency of the admixture.

  

Combination with SCM’s and Other Admixtures:
SikaControl® SC is compatible with commonly used SCM’s and other Sika admixtures. Do not premix with other admixtures.
Consumption

Recommended Dosage

The recommended dosage range for SikaControl® SC is from 2 to 7 % by weight of cement mass for concrete, mortars or grouts.

  
When trial mixes are performed for mix approval, ensure that all materials used are representative of the materials to be used during actual production.
