Sikament®-160

Water reducing/plasticising admixture

Sikament®-160 is a liquid admixture that is a formulated combination of modified lignosulphonates and naphthalene condensate.

  • Water reduction, resulting in higher density, higher strength and reduced permeability
  • Reduced shrinkage during curing
  • Reduction / replacement of cement
  • More economic mix design

Application Information

Compatibility

Sikament®-160 may be combined with many other Sika products.
Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information and advice about any specific combinations.

Dispensing

  • Sikament® 160 is added to the gauging water or added with it into the concrete mixer.
  • To take advantage of the optimum water reduction, a wet mixing time, which is depending on the mixing conditions and mixer performance, of at least 60 seconds is recommended.
  • To avoid excess water in the concrete, the final dosage must begin only after 2/3 of the wet mixing time.
Consumption

Recommended Dosage

0.3 – 1.0% by weight of cement
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 early as possible.
     

CLEANING OF TOOLS
 

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
 

NOTES ON APPLICATION / LIMITATIONS
 

  • When using Sikament®-160 a suitable mix design has to be taken into account and local material sources shall be trialled.
  • Sikament®-160 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, Sikament®-160 may be used after thawing slowly at room temperature followed by intensive remixing.
