SikaPlast®-3259 GL

(former MasterGlenium® 3259)

Polycarboxylic ether superplasticizer for the production of high quality ready-mix concrete

SikaPlast®-3259 GL is an innovative second generation superplasticizer based on polycarboxylic ether (PCE) polymers and is specially engineered for ready-mixed concrete.
SikaPlast®-3259 GL is differentiated from conventional superplasticisers, such as those based on sulphonated naphthalene formaldehyde condensate in that it is based on a unique carboxylic ether polymer with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process the same electrostatic dispersion occurs but the presence of the lateral chains, linked to the polymer backbone, generate a steric hindrance which stabilises the cement particles capacity to separate and disperse. This mechanism provides flowable concrete with greatly reduced water demand.

For the Ready-mix Producer:
  • Capability of delivering high performance concrete at any time to the job site in place
  • Production of a concrete with low water cement ratios with excellent workability retention properties.
  • Single product for many application needs
  • Assist partially with rheology improvement when using problematic aggregates
     For the Contractor / Applicator:
  • Easier placing and faster strength development
  • Improved concrete surfaces
  • Guarantee to place the same concrete as specified and ordered from ready-mix plant
     For the Engineer:
  • Insurance that concrete meets original specification
  • High quality durable concrete

System information

Compatibility

SikaPlast®-3259 GL is not compatible with Sikament RB superplasticizers.


SikaPlast®-3259 GL is suitable for mixes containing:

  • Microsilica (Silica Fume)
  • Fly Ash (PFA)
  • GGBS (ground granulated blast furnace slag)

    

The occurrence of a surface layer with SikaPlast®-3259 GL is normal and will have no effect on the performance of the product.

Application

Application Information

Dispensing

SikaPlast®-3259 GL is a ready-to-use admixture to be added to the concrete as a separate component.

Optimal result is obtained if SikaPlast®-3259 GL is poured into the concrete mix right after the addition of the first 80% of the mixing water, i.e. when all solids are wetted.

Avoid adding the admixture to the dry aggregates.

 
Consumption

Recommended Dosage

The normally recommended dosage rate of SikaPlast®-3259 GL is:

0.5 to 1.5 litre per 100kg of total cementitious material.


Other dosages may be recommended in special cases ac-cording to the specific site conditions.

In this case, please consult our Technical Services Department for advice.
