SikaPlast®-200

Shelf life when stored in dry warehouse conditions between 40 °F and 80 °F (5–27 °C) is 1 year from the date of manufacture.

SikaPlast®-200 should be kept above 35 °F (2 °C). If accidentally frozen, its properties can be restored by thawing and thoroughly re-mixing by mild mechanical agitation.

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. Please contact your local regional office or Technical Service Department at 1-800-933-7452 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.

The recommended dosage range for SikaPlast®-200 is 3.0 to 15.0 ounces per 100 lbs. (195 to 980 ml per 100 kg) 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.

When using SikaPlast®-200, the introduction of fly ash will enhance the retarding effect on the setting properties. Dosage rates vary depending upon the amount of plasticity and/or water reduction desired. Various concrete materials, slump, ambient air temperature, additions of pozzolanic materials, mixing time, and type and brand of cement will affect dosage rates. It is recommended that trial mixes be conducted in order to determine the required dosage for optimum performance with your concrete components. Consult your local Sika representative or Sika Technical Services Department at 1-800-933-7452 for dosage recommendations.
