POLARSET® ES is a non-corrosive, non-chloride admixture for concrete. It accelerates cement hydration resulting in shortened setting times and increased early compressive strengths.
POLARSET ES does not contain calcium chloride and is completely non-corrosive to reinforcing steel, metal decks and all metal components of your admixture storage and dispensing system.
It is formulated to comply with ASTM C494 Type C and can be used at any dosage to comply with ACI 318 guidelines for chloride content of concrete.

POLARSET ES is specially formulated to reduce concrete setting times and increase early strengths for concrete in very cold conditions, and may be used to reduce the time that concrete must be protected against freezing in ambient temperatures as low as -7°C. For conditions not subject to freezing, POLARSET ES may be used to speed finishing operations and/or form removal, leading to savings in concrete construction costs
POLARSET ES provides set time acceleration and early strength development similar to that provided by calcium chloride, but without the potential corrosive effects. POLARSET ES can therefore be used where potential corrosion of embedded or stressed steel must be avoided. It can also be used in concrete that is to be placed on steel clad or zinc coated steel decks where corrosion must be similarly avoided.
In concrete mixes, POLARSET ES accelerates the chemical reaction between Portland cement and water. It speeds up the formation of gel, the binder that bonds concrete aggregates together. Accelerated gel formation in turn shortens the setting time of concrete, compensates for the set-slowing effects of cold weather and contributes to the development of higher strengths. Gel formation promotes heat generation within the mix helping to protect the concrete from freezing during the critical first hours after placement.
Range: 500 ml–5500 ml per 100 kg cement
0.50%–5.00% volume by weight of cement
The amount of POLARSET ES used will depend on specific job conditions, on local materials and on the degree of set acceleration and early strength development required but levels as high as 6800 ml/100 kg of cement can be used. For freeze protection purposes typical addition rates are between 3800 to 5300 ml/100 kg of cement.
POLARSET® ES is compatible with most GCP Applied Technologies admixtures as long as they are added separately to the concrete mix, usually through the water holding tank discharge line. In general, it is recommended that POLARSET ES be added to the concrete mix near the end of the batch sequence for optimum performance. Different sequencing may be used if local testing shows better performance. Please see GCP Technical Bulletin TB-0110, Admixture Dispenser Discharge Line Location and Sequencing for Concrete Batching Operations, for further recommendations. POLARSET ES should not come into contact with any other admixture before or during the batching process, even if diluted in mix water.
Pretesting of the concrete mix should be performed before use, and as conditions and materials change in order to assure compatibility, and to optimize dosage rates, addition times in the batch sequencing and concrete performance. For concrete that requires air entrainment, the use of an ASTM C260 airentraining agent (such as Daravair® or Darex® product lines) is recommended to provide suitable air void parameters for freeze-thaw resistance. Please consult your GCP representative for guidance.
Since POLARSET ES may be used at high dosages, the concrete producer should account for the water contained in the POLARSET. Each liter of POLARSET ES added to a concrete mix will contribute 0.21 kg/l of water to that mix.
POLARSET ES is supplied in 210 litre non-returnable drums.
Alternatively, 1,000 litre IBCs and bulk deliveries can be arranged.
POLARSET ES freezes at approximately -23°C, but its set acceleration, strength gain and non-corrosive properties are completely restored by thawing and thorough agitation.
A complete line of accurate dispensers is available. POLARSET ES may be introduced on the sand, in the water, or at the end of the batch cycles. Similar to all concrete admixtures, POLARSET ES should not come in contact with other admixtures prior to entering the concrete.
The set-accelerating admixture shall be POLARSET ES, noncorrosive, non-chloride set accelerator, as manufactured by GCP. The admixture shall be used in strict accordance with the manufacturers’ recommendations. The admixture shall comply with ASTM Designation C494 Type C and will not contain purposely added chlorides or contribute to steel corrosion. Certification of compliance will be made available upon request.
Concrete shall be proportioned in accordance with Recommended Practice for Selecting Proportions for Normal Weight Concrete, ACI 211.1 or Recommended Practice for Selecting Proportions for Structural Lightweight Concrete, ACI 211.2, or in accordance with ACI 318.
Note to specifier: For use in freeze protection, request sample specification available from your GCP Engineering Services representative.
