SikaControl®-245 WT Liquid

CRYSTALLINE PERMEABILITY REDUCING ADMIXTURE

SikaControl®-245 WT Liquid is an integral liquid crystalline based permeability reducing admixture. SikaControl®-245 WT Liquid is formulated to meet the requirements of ASTM C494/AASHTO M 194, Type S and NSF/ANSI/CAN 61.

SikaControl®-245 WT Liquid uses a unique combination of active ingredients which react with ingress moisture within concrete. This reaction forms insoluble compounds throughout the capillary system in the concrete matrix resulting in crack healing properties and an improved resistance to water permeability. Additionally, SikaControl®-245 WT Liquid has minimal impact on setting characteristics and strength characteristics.   SikaControl®-245 WT Liquid also provides the following benefits:  
  • Uniform permeability reduction throughout the treated concrete volume,
  • Improved resistance against hydrostatic pressure,
  • Ability to seal non-moving concrete cracks up to 0.016 in (0.40 mm),
  • Improved durability and service life,
  • Lower construction costs compared to traditional types of waterproofing,
  • Potentially eliminates the risk of damage to traditional types of waterproofing systems during the construction process.
  In addition to the use of SikaControl®-245 WT Liquid it is recommended the concrete is designed for a minimum cementitious content of 590 lbs per cubic yard and a maximum water/cementitios ratio of 0.42. For optimum permeability reduction, proper curing of freshly placed concrete per ACI 308R-01 - Guide to Curing Concrete should be followed.   SikaControl®-245 WT Liquid does not contain intentionally added chlorides.

Approx. 1.130

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add SikaControl®-245 WT Liquid directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do NOT mix with dry cement. SikaControl®-245 WT Liquid 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.

 

Compatibility: SikaControl®-245 WT Liquid 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 rate of SikaControl®-245 WT Liquid is 1% by weight of cement or cementitious materials. The mix water should be reduced by an equivalent amount of SikaControl®-245 WT Liquid used in the concrete. Various factors will affect the dosage rates.

 

Trial mixes with the actual materials should be conducted to determine the required dosage for optimum performance.

 

To the extent specialized materials are used, extreme ambient temperatures are encountered, or for other unusual project conditions, dosage rates outside the typical range may be required. For dosage rates outside the typical range, please contact your local Sika representative or the Sika Technical Services Department at 1-800-933-7452.
