Mid Range Water Reducers - SikaPlast®-200

Mid-Range Water Reducing Admixture

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 C 494, Type A and Type G.

• Increased workability and easier placeability.
• Improved finishing characteristics.
• Mid-range water-reducing characteristics.
• Easier and faster pumping of concrete.
• Reduced shrinkage and cracking.
• 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.
SikaPlast®-200 is a non-chloride based admixture.

Shelf Life

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.

Storage Conditions

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.

Specific Gravity

Application

Application Information

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.

Combination with Pozzolanic Materials: SikaPlast®-200 can be successfully used in mix designs utilizing pozzolanic materials such as fly ash and GGBFS.

Consumption

Recommended Dosage

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.
