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

Description

Aydosper® EDUS 4S is a superplasticizer concrete additive that significantly reduces the concrete mix water, increasing both early and final strengths or providing flowability to concrete with the same amount of mix water. It also provides set-retarding properties. By delaying the setting time, it extends the hydration period of the cement with water and slows down the heat of hydration, ensuring long workability.

Applications

• Concrete production requiring delayed setting at high temperatures.

• Concrete requiring high final strength.

• Concrete requiring dense and smooth surfaces.

• Reinforced concrete production with placement difficulties, especially with densely reinforced sections.

• Concrete requiring excellent flowability and consistency retention.

• Concrete requiring impermeability.

• Preventing cold joints.

• Areas requiring re-vibration.

• Applications requiring long-distance transport.

Properties / Advantages

• Retains consistency for a long time in hot weather, reducing the need for re-adjustment.

• Provides self-leveling properties to the concrete.

• Significantly reduces the concrete mix water.

• Provides high unit weight and strength.

• Enhances workability.

• Extends the concrete’s setting time.

• Facilitates pumping.

• Eliminates noise pollution by eliminating the need for vibration.

• Provides a smooth, void-free surface.

• Eliminates the risk of segregation.

• Improves mechanical properties such as shrinkage and creep.

Dosage

• It is recommended to use between 0.8 – 1.8 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 perform preliminary trial mixes in the laboratory to determine the correct dosage.
