Setting retardant concrete admixture
TS EN 934 - 2 Çizelge 8 Priz geciktirici beton katkısı
• Used in concretes that require high final strength,
• In concretes to ensure high water reduction and long workability,
• Used in pouring concrete at high temperatures,
• In pouring concrete with a long period of delay,
• In production of concrete with thin and compact reinforcements for difficult compacting,
• In concretes that are required to have compact and smooth surface,
• Areas which will be subjected to vibration again.
• Ensures controlled prolongation of setting of concrete.
• Does not have adverse effects on final strengths.
• Reduces creeping and contraction.
• Extends the setting time of concrete.
• Increases workability.
• Minimizes the effects of temperature.
• Reduces segregation and bleeding of concrete.
• Ensures easy pumping.
• Prevents the concrete from losing its viscosity fast, provides for extended viscosity protection depending on the type of cement used.
• Prevents shrinkage cracks that may result from high hydration temperatures.
• Is suggested to be used as 0.5 – 2.0 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.
