Sika® Plastiment®-180
Water reducing/plasticising admixture
Plastiment® 180 is a liquid admixture which is formulated from modified lignosulphonates.
- Water reduction, resulting in higher density, higher strength and reduced permeability
- Reduced shrinkage during curing
- Opportunities for cost optimisation
- Cement replacement / reduction
- More economic mix design
Usage

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
Compatibility
Plastiment® 180 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
Plastiment® 180 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.
Restrictions
When using Plastiment® 180 a suitable mix design has to be taken into account and local material sources shall be trialled.
Plastiment® 180 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, Plastiment® 180 may be used after thawing slowly at room temperature followed by intensive remixing.
Recommended Dosage
0.3 – 0.7% by weight of cement
