Aydosper SF 1025

High-Performance Superplasticizer Concrete Admixture

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

Description
Aydosper® SF 1025 is a liquid, naphthalene sulfonate-based superplasticizer designed to significantly reduce water content while improving early and final strengths. It is specifically formulated to reduce the amount of cement used in mass concrete to lower the heat of hydration, or to provide the necessary workability and ease of placement without increasing water content.

Applications

• In high-quality and high-strength concrete production

• For concrete requiring dense and smooth surfaces

• In concrete mixes requiring significant water reduction and extended workability

• For applications requiring early form removal or fast loading

• In reinforced concrete with difficult placement due to fine and closely spaced reinforcement

• For precast and prefabricated concrete production

• In ready-mixed concrete production

Features / Advantages

• Produces durable, high-quality concrete

• Allows normal setting time without any retarding effects

• Increases concrete’s resistance and durability against freeze-thaw cycles

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

• Improves concrete’s impermeability with a low water/cement ratio

• Facilitates long-distance pumping of concrete

• Reduces curing time and temperature in precast element production, leading to energy savings

• Provides smooth, uniform concrete surfaces

• Eliminates segregation risk

• Ensures easy placement, faster strength gain, and labor savings, allowing earlier form removal or turnover

Dosage

• Recommended dosage: 0.6 – 1.8 kg per 100 kg of binder (cement, microsilica, fly ash).
• Dosage may vary based on aggregate properties, concrete class, water/cement ratio, water quality, and ambient temperature.
• Therefore, laboratory trial mixes are recommended to determine the optimal dosage.
