EN 934-2 Table 11.1 and 11.2: Set Retarding / High-Range Water-Reducing / Superplasticizer Concrete Admixture

Description
Aydosper® FNY S is a high-performance superplasticizer concrete admixture containing polymer-type liquids and organic retarders. It is especially suitable for use in hot, humid, and windy climates to facilitate easy placement. By interfering with the hydration process between water and cement, it slows down the reaction, thereby delaying setting time. At the same time, it maintains workability without increasing mixing water and improves final strength through its high water-reducing capacity.

Applications

• In high-strength, high-quality concrete

• Where high-range water reduction and extended workability are required

• In areas where cold joints must be avoided

• In concrete subject to multiple vibrations

• In long-distance concrete transport

• In concrete requiring impermeability

• In reinforced concrete with dense or complex reinforcement

• In concrete requiring smooth and dense surface finishes

• In ready-mix, precast, and prefabricated concrete production

Features / Advantages

• Prevents rapid loss of workability; ensures long slump retention depending on cement type

• Produces durable, high-quality concrete

• Provides controlled extension of setting times

• Enhances pumpability

• Prevents shrinkage cracks due to high heat of hydration

• Reduces segregation and bleeding, increasing abrasion resistance

• Slows carbonation rate, improves mechanical properties like shrinkage and creep

• Eliminates need for vibration, avoiding noise pollution

• Greatly reduces water demand in the mix

• Produces impermeable and excellent surface finishes

• Provides self-compacting properties

• Enables higher unit weight and compressive strength

Dosage

• Recommended dosage is between 0.6 – 2.0 kg per 100 kg of binder (cement, microsilica, fly ash).
• Dosage may vary depending on aggregate properties, concrete grade, water/cement ratio, water quality, and ambient temperature. Therefore, laboratory trial mixes are recommended to determine the optimal dosage.
