Aydos Kıvam Arttırıcı (Stabilizer)

Especially in the summer, re-dosing admixture added to concrete in concrete to prevent loss of consistency of concrete.

Description
Aydos® Kıvam Arttırıcı (Stabilizer) modified polymer based, liquid re-dosing admixture added into concrete in worksites in order to prevent loss of viscosity especially during summer months.

In eliminating loss of viscosity due to hot, windy and humid weather.
In pouring concrete with a long period of delay,
In ready-mix concrete, in pouring precast and prefabricated concrete.

Ensures workability of concrete by increasing the lost viscosity without addition of water.
Prevents resistance loss.
Suitable for use in all seasons by adjusting the dosage.
Increases workability.
Reduces segregation and bleeding of concrete.
Ensures easy pumping.
Ensures achieving a more compact concrete.
 

Dossage

Is suggested to be used as 0.4 – 1.0 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 laborator

Application/Warning

Used by directly mixing into the concretes which has difficulty compacting due to loss of viscosity.
Example: In case of adding water or admixture into a concrete which was produced with admixtures in the manufacturing plant, the effects on the properties of fresh and hardened concrete are given below: 
the mixing time should be prolonged for minimum 1-2 minutes at high speed and such mixing time should be determined during laboratory tests.

Concrete components may differ by their structures. The admixture to be added into the mixture to prevent segregation of the concrete should be applied in the suitable doses. Prior tests should be performed to check whether the admixture is suitable for the design of a certain concrete.
In case of using the admixture in the amount exceeding the specified use range, the setting time of the concrete may be prolonged. In such cases, the concrete should be kept humid to allow for curing until it hardens. 
Aydos® Kıvam Arttırıcı (Stabilizer) does not contain chloride or any other components that result in corrosion in the reinforcements. Therefore, it is suitable for use in reinforced concrete structures.
