Polydos SNY 590

High-Performance Superplasticizer Concrete Admixture

Standard
Ministry of Public Works Specification No: 04.613/1-A3
TS EN 934-2 Tables 11.1 and 11.2: Set Retarder / High-range Water Reducing / Superplasticizer Concrete Admixture

Description
Polydos® SNY 585 is a next-generation hyperplasticizer set-retarding concrete admixture based on polycarboxylate. It is specially developed for the ready-mix concrete industry, providing the necessary workability time. By significantly reducing water content, it enables the production of self-compacting concrete with high early strength, impermeable properties, and excellent surface appearance, all with a low water/cement ratio while maintaining consistency.

Areas of Use

• In concrete requiring long workability and consistency in hot climate conditions

• In the production of very high-performance concrete

• In concrete requiring plastic consistency and flowability

• In mass pouring concrete applications

• In injection and ground applications

• In the production of impermeable concrete

• In architectural concrete, engineering, and artistic structures

• In floor and field concrete

• In foundation, slab, beam, column, and wall concrete

• In bridge, viaduct, tunnel, airport, and dam concrete

• In the production of all types of concrete with placement challenges, including fine, heavily reinforced, or non-reinforced lightweight or normal-weight concrete

• In the production of self-compacting concrete (SCC)

Properties / Advantages

• Provides significant increase in both early and final strength of concrete

• Maintains consistency of concrete for a long time during summer, without requiring re-adjustment

• Reduces the amount of water in concrete mixtures by 25-35%, significantly lowering water content

• Prevents shrinkage cracking due to high hydration heat

• Reduces the carbonation speed of concrete

• Provides self-compaction properties to the concrete

• Allows high unit weight and strength

• Eliminates the risk of segregation

• Improves the impermeability of concrete due to the low water/cement ratio

• Increases pumpability

• Allows a dense and smooth surface finish

• Eliminates noise pollution by eliminating the need for vibration

Dosage
For flowable and self-compacting concretes, it is recommended to use between 0.4 – 2.0 kg per 100 kg of binder (cement – microsilica – fly ash).
The admixture dosage may vary depending on aggregate properties, concrete class, water/cement ratio, water quality, and ambient temperature. Therefore, trial mixes in the laboratory are strongly recommended.
During consistency adjustments, the admixture’s high water-reducing effect must be considered, and excess water should not be added to the mix.
