Auramix 269 - New generation plasticiser admixture. High workability maintenance

New generation plasticiser admixture. High workability maintenance. Dosage: 0.5-1.2% over cement weight.



  • To obtain a quality concrete, compactness, durability and resistance.
  • To obtain a concrete of excellent workability reducing the proportion of water of kneading and improving docility.
  • To achieve a maintenance of the workability of the concrete higher than that obtainable with conventional plasticizers.


  • Strong reduction of water: between 15 and 25% according to the dosages used.
  • The incorporation of new synthesis molecules greatly improves the appearance and compactness of the concrete.
  • The plasticizing effect is maintained, even in hot climates.


Auramix 269 complies with UNE-EN 934-2: 2010 Table 2 as a water reducer / plasticizer.


Auramix 269 is a multifunctional plasticizer, based on synthetic and natural polymers intended for the preparation of prepared concrete, with a high water reducing power and dispersant of the cement particles.

Typical dosage

The optimal dosage of Auramix 269 to achieve specific requirements should be determined by testing the materials and conditions under which it will be practiced.

A starting point for such tests is to employ a dosage of 0.5-1.2 liters per 100 kg of cementitious material, including ash, slag or microsilica.


The following results were obtained at a temperature of 20 ° C:

  • Appearance: Light brown liquid
  • Density: 1.08 ± 0.01 kg / l pH: 6.5 ± 1.0
  • Content in water-soluble chlorides (CI-): ≤ 0,10%
  • Alkaline content (Na2O equivalent): max. 7% by mass
  • Main function: Increase workability
  • Secondary function: Increase mechanical resistance
