DARATARD®
Set Retarders
DARATARD® solutions act to delay the hydration reactions of the cement, consequently prolonging its workability, but without changing its initial consistency.
Once the setting period is over, the concrete hardens quickly, resulting in high mechanical resistance after 28 days of curing. DARATARD® agents do not have any surfactant effect on concrete, which means they do not alter its consistency or rheological behaviour.
