Polydos TN 347-K

High-Performance Hyperplasticizer 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® TN 347K is a new generation hyperplasticizer concrete admixture based on polycarboxylate, developed with advanced technology for the ready-mix concrete industry. It provides high water reduction at low dosage levels, extended workability, and high strength.

Areas of Use

• In concrete requiring early high strength under cold climate conditions

• In all high-quality concretes where high strength and low water/cement ratio are desired

• In site concretes, precast, and prefabricated concretes where rapid formwork removal is needed

• In concretes demanding high water reduction and long workability

• In the production of all types of concrete with or without reinforcement, lightweight or normal weight, with difficult placement conditions

• In concretes where a plastic consistency and good flow are required

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

Features / Advantages

• Enables production of durable, high-quality concrete

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

• Increases resistance and durability of concrete against freeze/thaw cycles

• Improves impermeability due to a low water/cement ratio

• Provides self-compacting properties to concrete

• Allows for higher unit weight and strength

• Enables pumping of concrete over long distances

• Reduces curing time and temperature in precast production, leading to energy savings

• Ensures normal setting time without retardation

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

• Produces smoother and more aesthetically pleasing concrete surfaces

• Eliminates the risk of segregation

• Facilitates easy placement and faster strength development, saving labor and allowing earlier formwork removal or turning

Dosage

For flowable and self-compacting concretes, it is recommended to use between 0.4 – 1.8 kg per 100 kg of binder (cement – microsilica – fly ash).
The dosage may vary depending on aggregate characteristics, concrete class, water/cement ratio, water quality, and ambient temperature. Therefore, it is recommended to determine the appropriate dosage through laboratory trial mixes.
During consistency adjustment, the high water-reducing efficiency of the admixture should be considered, and excessive water addition should be avoided.
