SikaPlast®-200
MID-RANGE WATER-REDUCING ADMIXTURE FOR CONCRETE
SikaPlast®-200 is a mid-range water-reducing admixture specifically formulated to enhance the finishability and workability of concrete. SikaPlast®-200 meets the requirements of ASTM C494, Type A and Type G.
- Increased workability and easier placeability
- Dramatically improved finishing characteristics for flatwork
- Mid-range water-reducing characteristics
- Easier and faster pumping of concrete
- Reduced shrinkage and cracking
- Reduces segregation at a given slump
- Reduced permeability
- Increased concrete durability and uniformity
- Improved appearance of architectural concrete
- Increased strength at all ages
Usage
SikaPlast®-200 can be used in all types of concrete including plain, reinforced, extruded, precast and prestressed concretes. SikaPlast®-200 is especially effective in concrete containing such pozzolanic materials as fly ash, silica fume and slag.Advantages

Application
Mixing
For best results, SikaPlast®-200 should be added directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle. SikaPlast®-200 may also be dispensed as an integral material during the regular admixture batching cycle or into freshly mixed concrete in a ready-mix truck at the concrete plant or job site. To optimize the superplasticizing effect, Sika recommends that the combined materials be mixed for 80-100 revolutions, either in the concrete mixer or in the ready-mix truck.
Combination with other admixtures: SikaPlast®-200 is highly effective as a single admixture or in combination with other Sika admixtures. If more than one admixture is used, the admixtures must be added separately to the concrete mix. Contact your local Sales Representative for further information.
Combination with pozzolanic materials: SikaPlast®-200 can be successfully used in mix designs utilizing pozzolanic materials such as fly ash and GGBFS.
Recommended Dosage
The typical dosage range for SikaPlast®-200 is 195-980 mL per 100 kg (3-15 fl. oz/100 lb) of cementitious material.
At a low and moderate dosage rate, SikaPlast®-200 acts as a Type A, water-reducing admixture. At a higher dosage rate, it acts as a Type G, high range water-reducing and retarding admixture. Dosage rates vary depending upon the amount of plasticity and/or water reduction desired. Slump, ambient temperature, water-cementitious ratio, mixing time and various concrete materials, such as type of cement and supplementary cementitious materials, will affect dosage rates. It is recommended to conduct trial mixes with the actual materials to determine the required dosage for optimum performance.
To the extent specialized materials (such as microsilica) are specified, extreme ambient project conditions are encountered, or other unusual project conditions require special consideration outside the recommended dosage, contact your Sika Canada Technical Sales Representative for further information.
