Shrinkage Reducing Admixtures - SikaControl®-75

SHRINKAGE REDUCING ADMIXTURE

SikaControl®-75 is a shrinkage reducing admixture used to produce high performance concrete with greatly reduced drying shrinkage. SikaControl®-75 conforms to the requirements of ASTM C494 Type S.

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

SikaControl®-75 does not contain intentionally added chlorides.

Usage

SikaControl®-75 can be used in any type of cast-in-place or precast/prestressed concrete, grouts, mortars or any other cementitious mixes. Some of the applications of SikaControl®-75 may include:

• Concrete floors, to compensate for drying and autogenous shrinkage, cracking, control curling and increase joint spacing.
• Utilized in topping slabs to minimize cracking.
• For durable concrete in marine environments.
• For watertight concrete in reservoirs, sewage treatment plants and dams.
• Minimize shrinkage in heavily restrained structures.

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 and life cycle.

SikaControl®-75 does not contain intentionally added chlorides.

Packaging

SikaControl®-75 is available in 55 gallon drums (208 liters), 275 gallon totes (1040 liter) and bulk supply.

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add SikaControl®-75 directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do not mix with dry cement. SikaControl®-75 may be dispensed on site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.

For use in air entrained concrete, the dosage of the air entrainment admixture may need to be adjusted. Conduct trial mixes to evaluate and confirm air entrainment admixture dosages, as well as concrete properties prior to production use.

Compatability:
SikaControl®-75 can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.

Consumption

Recommended Dosage

The typical dosage range of SikaControl®-75 is 8-30 fluid ounces per 100 lbs. (502-1950 ml / 100 kg) of cementitious for general concrete applications. Laboratory tests show that at a dosage of 30 fluid ounces per 100 lbs. of cementitious, shrinkage over the long term can be reduced by as much as 40%.

To the extent specialized materials (such as microsilica) are specified, extreme ambient project conditions are encountered, or other unusual project conditions require special consideration outside the recommended dosage.
