Aydosper SLK 5 S

High Performance Superplasticizer Concrete Additive

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® SLK 5S is a superplasticizer concrete admixture that significantly reduces the mix water content, increasing both early and final strengths, or imparts high flowability with the same amount of mixing water. It also has set-retarding properties. By extending the setting time, it prolongs the cement's hydration period and slows down the heat of hydration, ensuring long workability.

Applications

• Concrete production requiring long setting delay at high temperatures

• Concrete with high final strength requirements

• Concrete with dense and smooth surface requirements

• Reinforced concrete applications with tightly spaced reinforcement

• Concrete requiring excellent fluidity and consistency retention

• Concrete where impermeability is desired

• Prevention of cold joints

• Areas subject to re-vibration

• Projects involving long-distance transportation of concrete

Properties / Advantages

• Maintains concrete consistency for long periods during summer without the need for re-adjustment

• Provides self-compacting ability

• Significantly reduces water content in concrete mix

• Enhances unit weight and compressive strength

• Improves workability

• Extends setting time of concrete

• Facilitates pumping over long distances

• Eliminates the need for vibration, reducing noise pollution

• Produces void-free and smooth surface finishes

• Eliminates segregation risk

• Improves mechanical properties like shrinkage and creep

Dosage

• It is recommended to use between 0.6 – 2.0 kg per 100 kg of binder (cement, microsilica, fly ash).
• The exact dosage may vary based on aggregate properties, concrete class, water/cement ratio, water quality, and ambient temperature. Therefore, it is advised to determine the appropriate dosage by conducting preliminary laboratory trial mixes.
