Superplasticizing concrete admixture
Superplasticizing concrete admixture
TS EN 934-2 Çizelge 3.1 ve 3.2: Yüksek oranda su azaltıcı / süperakışkanlaştırıcı beton katkısı
• Used in concretes that require high final strength,
• In concretes that are required to have compact and smooth surface,
• In concretes to ensure high water reduction and long workability,
• Where it is necessary to mold early or load the molds quickly,
• In foundation, apron, beam, column and shear concretes,
• In bridge, viaduct, tunnel, airport and dam concretes,
• In production of concrete that are intended to be impervious,
• In precast and prefabricated concrete production,
• Does not have any retarding effects and ensures setting of concrete in normal period of time.
• Allows for achieving high unit weight and strength.
• Ensures pumping of the concrete to long distances.
• Saves on energy by reducing the curing time and temperature in production of precast members.
• Increases the resistance of concrete in its freeze - thaw cycle, improves mechanical properties such as shrinkage and creep.
• In concrete applications with low water / cement ratio, it provides easy settlement and smooth surface without loss of workability.
• Is suggested to be used as 0.8 – 1.9 kg for 100 kg binder (cement microsilica fly ash). Dosage of contribution is based on the aggregate properties, water quality, concrete class, water-cement ratio and temperature of place. Therefore, it is recommended to determine the dose by preparing test mixtures in a laboratory.
