Description
Aydosper® SF 04 AS is a superplasticizer concrete admixture based on naphthalene sulfonate and organic retarders, which significantly reduces the water content of the mix, increasing the final strength of the concrete or enhances the fluidity of the concrete without increasing the mix water. It is designed for use in hot weather conditions, providing high workability and easy placement of concrete, while maintaining consistency for normal concrete or micro-silica concrete mixes. It is ideal for producing concrete that retains workability for extended periods without the need for re-mixing.

Applications

• In concrete mixes where high final strength is required

• In hot climates where long workability and consistency are needed

• For concrete with difficult placement, including highly reinforced or unreinforced lightweight and normal-weight concretes

• Where significant water reduction and extended workability are desired

• For producing dense and smooth concrete surfaces

• For producing impermeable concrete

• In pre-stressed, precast, and ready-mixed concrete applications

Features / Advantages

• Maintains the consistency of concrete for a long period during hot weather, eliminating the need for re-mixing

• Improves concrete impermeability with a low water/cement ratio

• Provides higher unit weight and strength

• Facilitates long-distance pumping of concrete

• Achieves smoother, aesthetically pleasing concrete surfaces

• Enhances concrete's durability and resistance to freeze-thaw cycles

• Provides self-compacting properties to the concrete

• Reduces carbonation rate and improves mechanical properties such as shrinkage and creep

• Allows for easier placement and faster strength gain, reducing labor costs and enabling earlier formwork removal or turnaround

Dosage

• Recommended dosage: 0.8 – 2.0 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, trial mixes in a laboratory setting are recommended to determine the optimal dosage.
