High performance hyper plasticizing concrete admixture

Standard
Bayındırlık Bakanlığı Poz No: 04.613/1-A3 TS EN 934-2 Table 3.1 and 3.2: High range water reducing / superplasticizing concrete admixture

 

Description
Polydos® EST 81 especially developed for pre-concrete and pre-casting industries which require high-speed water reduction, early and final high strength and durability, it is a new generation super-plasticizer concrete admixture which can easily settle on compact reinforced concrete members and can enable production of self-compacting concrete with viscosity protection.

In the production of self-compacting concrete which can easily settle on compact reinforced concrete members,
In prefabricated concrete that does not degrade and requires high workability,
In the production of concrete requiring early high strength,
In the production of precast and prefabricated concrete,
In the production of ready mixed concrete.

Provides early high strength concrete production even at low temperatures.
Reduces the curing time and temperature in the production of precast elements and shortens the molding time.  
Increases the resistance of concrete in its freeze - thaw cycle, improves mechanical properties such as shrinkage and creep.
Improves the wear resistance of concrete by decreasing disintegration and perspiration.
In concrete applications with low water / cement ratio, it provides easy settlement and smooth surface without loss of workability

For flowing and self-compacting concrete; Is suggested to be used as 0.4 - 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.
When adjusting the consistency, high water cut-off property of admixture should be taken into account and more water addition should not be done to mixture.
