Sika® ViscoCrete®-58 HT-PK

High Range Water Reducing, Superplasticizer & Slump Retaining Admixture

Sika® ViscoCrete®-58 HT-PK is a high range water reducing, slump retaining and super plasticizing admixture for Concrete & Mortar utilizing Sika® ViscoCrete®-58 HT-PK polycarboxylate polymer technology (3rd Generation).

Sika® ViscoCrete®-58 HT-PK is a powerful super-plasticizer which acts through several different mechanisms including surface adsorption and sterically effects separating the cementitious binder particles. The following advantages properties are achieved:
  • High water reduction, resulting in high density, high strength, and reduced permeability
  • Superior plasticizing effect, resulting in improved flow, placing and compaction characteristics
  • Reduced shrinkage during curing and reduced creep when hardened.
  • Chloride Free; thus, no corrosion effect on steel.
  • Reduced rate of carbonation of the Concrete.
  • NO need for vibration, thus NO noise pollution.
  • Suitable for Summer conditions & pumpability, thanks to its long-time consistency

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.

Application

Application Information

Compatibility

Sika® ViscoCrete®-58 HT-PK can be used in conjunction with:

  • SikaFiber®
  • SikaPlastoCret®-N
  • SikaAntiFreeze®
  • SikaRetarder®
  • SikaRapid®
  • SikaAER®

All admixtures must be added separately. Trials are always recommended before combining products. For additional information, please contact Sika technical personnel.

Dispensing

Sika® ViscoCrete®-58 HT-PK is added to the gauging water or added with it into the concrete mixer. To take advantage of the high water reduction, a wet mixing time, which is depending on the mixing conditions and mixer performance, of at least 2 mins. per cubic meter after the admixture addition is recommended. Sika® ViscoCrete®-58 HT-PK shall not be added to dry cement.
Consumption

Recommended Dosage

Recommended dosage for concrete:

  • For plastic Concrete (0.2 - 0.4 %) by weight of Binder
  • For Flow & Self Compacting Concrete (0.3 - 1.5 %) by weight of Binder
  • Optimum dosage should be determined by site trials.

When adjusting the consistency, high water reduction property of the admixture must be taken in consideration; excessive water addition must be prevented.
Application steps

CLEANING OF TOOLS

Clean all equipment and tools with water immediately after use.
