SikaPlast®-168 SL

PCE BASED SUPERPLASTICIZING AND SET RETARDING CONCRETE ADMIXTURE

SikaPlast®-168 SL is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete. SikaPlast®-168 SL meets the requirements of ASTM C 494 Type D - G and BS EN 934 - 2

SikaPlast®-168 SL combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika-Plast®-168 SL effects the following concrete properties:
▪ Long slump keeping and high water reduction;
▪ High flowability (considerably reduced placing and compacting work);
▪ Faster evolution of early strength development;
▪ Improved creep and shrinkage resistance character-istics;
▪ When used at higher dosages, SikaPlast®-168 SL can give extended working time.
SikaPlast®-168 SL contains neither chlorides nor other corrosion inducing substances and can therefore be used without any restrictions for reinforced concrete structures.

Usage

SikaPlast®-168 SL is mainly suitable for the manufacture of concrete for RMC plants and site batch concrete. SikaPlast®-168 SL is used for the following types of concrete: ▪ Bored piles; ▪ Barrette foundations and diaphragm walls; ▪ Ground and suspended slabs; ▪ Columns and walls. ▪ Bridges and cantilever ▪ Cement mortar and grouts

Technical Information

Concreting guidance

Concrete placing: With the use of SikaPlast®-168 SL , concrete of highest quality is being produced, however state of the art concrete technology, such as mixing, placing vibrating and curing must be respected and applied. Curing: Effective measures for concrete curing must be followed.

Specific advice

SikaPlast®-168 SL is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix.
For optimum utilization of the ultra-high range water reducer we recommend a minimum wet mixing time of 60 seconds.When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.

Application

Application Information

Compatibility

SikaPlast®-168 SL may be combined with all Sikament, Sika® Aer, Sika® Pump, Sikacrete® PP-1 products, but must be added separately to the mix and not premixed prior its addition. SikaPlast®-168 SL is compatible with all Portland cement types.

Restrictions

Overdosing will result in increased workability and set-ting time of the Concrete, however, provided that curing is effective, ultimate concrete strength and properties will not be affected. Use an appropriate concrete mixer and do not mix by hand. Trial mixes are recommended to establish exact dosage rates required to suit individual requirements. Please contact Sika Technical Department for further assistance.
Consumption

Recommended dosage

0.5 – 2 L per 100 kg of cement
