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

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.
