Description
Aydosper® SF 12 S is a superplasticizer concrete admixture based on naphthalene sulfonate and organic retarders, which significantly reduces the mix water content to enhance the final strength of concrete or increases fluidity without increasing the mix water. It is ideal for use in hot weather conditions and is designed to achieve high workability, fluidity, and easy placement of concrete while maintaining consistency. This product is suitable for normal concrete mixes and micro-silica concretes with excellent consistency retention.

Applications

• In concrete mixes where high final strength is required

• In hot climate conditions where long workability and consistency retention are needed

• For concrete mixes with placement difficulties, including highly reinforced or unreinforced, lightweight or normal-weight concrete

• In concrete requiring significant water reduction and long workability

• For producing dense and smooth concrete surfaces

• In concrete requiring impermeability

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

Features / Advantages

• Maintains concrete consistency for an extended period in hot weather, eliminating the need for re-mixing

• Improves impermeability of concrete with a low water/cement ratio

• Provides a high unit weight and strength

• Facilitates long-distance pumping of concrete

• Produces smoother, more aesthetically pleasing concrete surfaces

• Enhances concrete durability and resistance to freeze-thaw cycles

• Imparts self-compacting properties to the concrete

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

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

Dosage
Recommended dosage: 0.6 – 1.7 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.
