Polydos TS 70-A

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® TS 70-A is a new-generation superplasticizer and setting accelerator concrete admixture, based on modified polycarboxylate, that provides high water reduction, early and final high strength, enhanced fluidity, and excellent slump retention.

Areas of Use

• In all high-quality concrete where high strength and low water/cement ratio are required

• In concrete requiring excellent flowability and slump retention

• In applications where early formwork removal or fast loading is necessary

• In the production of any type of light or normal-weight concrete with or without dense reinforcement where placement is difficult

• In concrete where dense and smooth surface finish is desired

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

Features / Advantages

• Chemical Content: Polycarboxylate-based

• Appearance-Colour: Brown liquid

• Density: 1.05 ± 0.02 kg/l (ISO 758)

• pH Value: 4.5 ± 1 (TS 6365 EN 1262)

• Chloride Content (Cl): < 0.1% (TS EN 480-10)

• Alkali Content: < 4% (TS EN 480-12)

• Freezing Point: -4 ºC

• Corrosion Behavior: Contains only components listed in TS EN 934-1 Annex A.1

• Dangerous Substances: Fully compliant with Annex ZA

• Manufacturing Conditions: Produced at +20°C and 50% relative humidity

• Provides significant improvement in both early and final concrete strength

• Greatly reduces the amount of mixing water required

• Ensures long-term slump retention

• Imparts self-compacting properties to concrete

• Enables void-free and smooth surface finish

• Enhances impermeability of concrete due to low water/cement ratio

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

• Increases concrete resistance to freeze-thaw cycles and heat

• Improves mechanical properties such as shrinkage and creep

• Enables easy placement and faster strength gain, leading to labor savings and earlier formwork removal or turnover

• Facilitates pumping of concrete

Dosage

For flowable and self-compacting concretes, it is recommended to use 0.5 – 2.0 kg per 100 kg of binder (cement – microsilica – fly ash).
The dosage may vary depending on aggregate properties, concrete class, water/cement ratio, water quality, and ambient temperature. Therefore, it is recommended to determine the dosage through preliminary trial mixes in the laboratory.
During consistency adjustment, the high water-reducing capacity of the admixture should be considered, and excessive water addition should be avoided.
