Description
Aydosper® 970 S is a superplasticizer and set-retarding concrete admixture that significantly enhances the final strength of concrete by reducing water content. It is designed for use in hot climates to produce fluid concrete with extended workability and set retardation properties, providing high performance in challenging conditions.

Applications

• Used in high-quality, high-strength concrete production

• For ready-mix concrete that needs to be transported over long distances in hot climates

• Concrete requiring excellent fluidity and prolonged workability

• Concrete with placement difficulties, such as densely reinforced concrete

• Concrete requiring smooth, dense surfaces

• Concrete where impermeability is essential

Features / Advantages

• Prevents rapid loss of workability, ensuring extended consistency depending on cement type

• Significantly improves early high strength development

• Provides self-compacting properties to the concrete

• Offers 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 the risk of segregation

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

• Enhances concrete's resistance to freezing

• Facilitates long-distance pumping of concrete

Dosage

• Recommended dosage: 0.7 – 1.8 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.
