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

Description

Aydosper® EN 15 is a high-performance superplasticizer concrete additive based on naphthalene sulfonate, used for producing concrete requiring high strength and impermeability. It enhances the rheoplastic properties of the concrete, preventing segregation, and is ideal for high-quality concrete production requiring significant water reduction.

Applications

• Concrete requiring early and high final strength.

• Concrete needing excellent flowability and consistency retention.

• Areas where early form removal or quick loading is required.

• Concrete production requiring impermeability.

• Architectural, engineering, and artistic concrete applications.

• Concrete elements with complex and detailed molds.

• Precast and prefabricated concrete production.

• Ready-mix concrete production.

Properties / Advantages

• Reduces segregation and bleeding, increasing wear resistance.

• Significantly reduces the water content in the concrete mix.

• Provides excellent self-compacting properties to the concrete.

• Provides significant early and final strength increases in concrete.

• Reduces the carbonation rate of concrete and improves mechanical properties like shrinkage and creep.

• Facilitates pumping concrete over long distances.

• Provides a smooth, void-free surface.

• Ensures the concrete sets at normal time without a retardant effect.

• Reduces curing time and temperature in precast element production, saving energy.

• Offers high unit weight and strength.

• Prevents rapid loss of consistency in the concrete.

Dosage

• For 100 kg of binder (cement-microsilica-fly ash), it is recommended to use between 0.8 – 1.9 kg.
• The dosage may vary depending on the aggregate properties, concrete grade, water/cement ratio, water quality, and ambient temperature. Therefore, it is recommended to conduct preliminary trial mixes in the laboratory to determine the correct dosage.
