Polydos TN 344

High-Performance Hyperplasticizer Concrete Admixture

Standard

Ministry of Public Works Specification No: 04.613/1-A3
TS EN 934-2 Table 3.1 and 3.2: High-Range Water Reducing / Superplasticizer Concrete Admixture

Description

Polydos® TN 344 is a new generation hyperplasticizer concrete admixture based on polycarboxylate, designed for the production of high-performance concrete with early and final high strength. Developed specifically for the ready-mix concrete industry, it enables the production of self-compacting and self-consolidating concrete without issues such as segregation or bleeding. It provides very high water reduction depending on dosage and offers extended workability time.

Areas of Application

• In higher quality and high-strength concretes

• In concrete requiring excellent flowability and slump retention

• In reinforced concrete structures with dense, closely spaced rebar where placement is difficult

• In concrete requiring high water reduction and long workability

• In applications requiring early formwork removal or rapid loading

• In precast and prefabricated concrete production

• In prestressed concrete manufacturing

• In architectural, engineering, and artistic concrete works

• In the production of Self-Compacting Concrete (SCC)

Features / Advantages

• Enables the production of durable, high-quality concrete

• Provides high early strength in a short time, especially in cold weather

• Improves resistance to freeze/thaw cycles

• Enhances impermeability thanks to low water/cement ratio

• Grants self-compacting properties to the concrete

• Allows high unit weight and strength to be achieved

• Ensures long-distance pumpability

• Saves energy by reducing curing time and temperature in precast production

• Allows normal setting without retarding effect

• Reduces carbonation rate and improves mechanical properties such as shrinkage and creep

• Provides smoother and aesthetically improved concrete surfaces

• Eliminates the risk of segregation

• Facilitates easier placement and faster strength development, resulting in labor savings and earlier formwork removal or turnover

Dosage

For flowable and self-compacting concretes, it is recommended to use 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, it is advised to determine the optimum dosage through preliminary trial mixes in the laboratory.
When adjusting the consistency, the high water-reducing capacity of the admixture should be considered, and excess water should be avoided.
