Sika® ViscoCrete®-4100 (GB)

WATER REDUCING CONCRETE ADMIXTURE WITH ENHANCED WORKABILITY RETENTION

Sika® ViscoCrete®-4100 (GB) is a liquid admixture for concrete based on a unique blend of polycarboxylate polymers technologies. Sika® ViscoCrete®-4100 (GB) is designed as a water reducer or plasticiser. It is particularly suited for use in concretes that require excellent workability retention properties of 4 hours+.

Water reduction resulting in higher strengths and densities
  • Extended consistence retention
  • Improved cohesion properties
  • Improved early and ultimate strengths
  • Excellent placement characteristics
  • Improved rheology
  • Improved durability
  • Reduced segregation and bleeding
  • Reduced drying shrinkage
  • Reduced mix costs

Application steps

APPLICATION INSTRUCTIONS

Application Method/Tools

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 soon as possible.



Notes on Application/Limitations
 

  • When using Sika® ViscoCrete®-4100 (GB) a suitable mix design has to be taken into account and local material sources shall be trialled.
  • Sika® ViscoCrete®-4100 (GB) shall not be added to dry cement.
  • Excessive water addition or overdosing may cause bleeding or segregation.
  • Support from our Technical Service Department is recommended.

Frost:
If frozen and / or if precipitation has occurred, Sika® ViscoCrete®-4100 (GB) may be used after thawing slowly at room temperature followed by intensive remixing.
