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