Aydosper 970 W

High-Performance Superplasticizer Concrete Admixture

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

Description
Aydosper® 970 W is a high-performance superplasticizer based on naphthalene sulfonate, designed to increase the fluidity of concrete, reduce mix water, and significantly enhance both early and final strength, while also extending the setting time without affecting the quality of the concrete.

Applications

• Increases early strength development, ideal for construction sites and precast concrete production

• Where rapid setting is required

• For producing concrete that requires impermeability

• Concrete mixes requiring plastic consistency and high flowability

• For concrete with placement difficulties, including fine, densely spaced reinforcement, and both lightweight and normal-weight concrete

• For concrete requiring high water reduction and long workability

Features / Advantages

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

• Alkali Content: < 5% (TS EN 480-12)

• Freezing Point: -5°C

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

• Dangerous Substances: Fully compliant with Annex ZA

• Produced at +20ºC, with 50% relative humidity conditions

• Provides rapid early strength development, especially in cold weather

• Prevents rapid loss of workability

• Provides self-compacting properties to the concrete

• Enables high unit weight and strength

• Produces low-porosity, smooth-surfaced, and less permeable concrete

• Eliminates the need for vibration, thus reducing noise pollution

• Reduces curing time and temperature in precast element production, resulting in energy savings

• Eliminates segregation risk

• Reduces the carbonation rate, improving mechanical properties like shrinkage and creep

• Increases concrete's resistance to freezing

• Facilitates long-distance pumping of concrete

Dosage

• Recommended dosage: 0.6 – 1.7 kg per 100 kg of binder (cement, microsilica, fly ash).
• Dosage may vary depending on aggregate properties, concrete class, water/cement ratio, water quality, and ambient temperature.
• Therefore, laboratory trial mixes are recommended to determine the optimal dosage.
