Aydosper SNK 3 S

High Performance Superplasticizer Concrete Admixture

Standard
Ministry of Public Works Poz No: 04.613/1-A3
EN 934-2 Table 11.1 and 11.2: Set Retarding / High-Range Water-Reducing / Superplasticizer Concrete Admixture

Description
Aydosper® SNK 3 S is a superplasticizer concrete admixture that significantly reduces the mixing water content, increasing both early and final strength, or enhances the flowability of concrete using the same water content. Thanks to its set-retarding properties, it prolongs the cement hydration period and slows the heat of hydration, providing long workability.

Applications

• Concrete production requiring long setting delay at high temperatures

• Concrete with high final strength requirements

• Concrete needing dense and smooth surface finishes

• Reinforced concrete with tight rebar placement

• Concrete requiring excellent fluidity and slump retention

• Concrete requiring high impermeability

• Prevention of cold joints

• Applications requiring re-vibration

• Concrete transportation over long distances

Features / Advantages

• Maintains workability over extended periods, especially in hot weather

• Provides self-compacting properties

• Greatly reduces mixing water content

• Ensures high unit weight and compressive strength

• Enhances overall workability

• Delays initial setting time

• Eases pumping over long distances

• Eliminates the need for vibration, reducing noise pollution

• Helps achieve void-free and smooth concrete surfaces

• Eliminates segregation risk

• Improves mechanical properties such as shrinkage and creep

Dosage

• Recommended dosage is between 0.7 – 1.8 kg per 100 kg of binder (cement, microsilica, fly ash).
• The exact dosage may vary depending on aggregate characteristics, concrete grade, water/cement ratio, water quality, and ambient temperature. Therefore, it is recommended to determine the appropriate dosage by conducting preliminary laboratory trial mixes.
