Description
Aydos® Retarder OV modified polymer based concrete admixture that delays the setting as much as needed.

For pouring voluminous concrete (mass concrete) and preventing cold joint formation where it is necessary to transport the concrete to long distances,
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 production of concrete that are intended to be impervious,
Areas which will be subjected to vibration again.
In eliminating loss of viscosity due to hot, windy and humid weather.

Ensures controlled prolongation of setting of concrete.
Does not have adverse effects on final strengths.
Reduces creeping and contraction.
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 0.4 – 2.2 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.
