Polydos EST 80

High-Performance Superplasticizer Concrete Admixture

Standard
Ministry of Public Works Specification No: 04.613/1-A3
TS EN 934-2 Tables 3.1 and 3.2: High-range water reducing / superplasticizer concrete admixture

Description
Polydos® EST 80 is a new-generation, polycarboxylate-based superplasticizer concrete admixture designed to produce high-strength and workable concrete without delay in setting time. It is specifically formulated for elements with high reinforcement, allowing self-compaction, high water reduction, and flowability. It is ideal for producing quality concrete with high performance and workability.

Areas of Use

• In the production of concrete for elements with dense reinforcement that can self-compensate and compact easily

• In precast concrete where high workability and no segregation are desired

• In concrete where early high strength is required in cold climate conditions

• In construction sites where quick form removal is required, in precast and prefabricated concrete production

• In the production of concrete where early high strength is desired

• In the production of ready-mixed concrete

Features / Advantages

• Ensures normal setting time without any delay

• Allows the production of early high-strength concrete even at low temperatures

• Reduces curing time and temperature in precast element production and shortens form removal time

• Increases freeze-thaw resistance and improves mechanical properties such as shrinkage and creep

• Reduces segregation and bleeding, increasing the wear resistance of concrete

• Ensures smoother and better-looking concrete surfaces

• Enables easy compaction and a smooth surface in low water/cement ratio concrete applications without loss of workability

Dosage
For flowable and self-compacting concretes, it is recommended to use between 0.7 – 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.
