Sika ViscoFlow®-2020

Sika® ViscoFlow-2020 can be used in conventional, high slump or Self Consolidating Concrete, in precast/prestress or ready mix applications, or in any application where extended concrete plasticity without excessive retardation is required. Sika® ViscoFlow-2020 does not extend slump life by slowing down the hydration process of cement. Due to the utilization of a new engineered time-released polymer that allows for controlled and consistent slump extension with minimum initial slump increase, Sika® ViscoFlow-2020 makes it possile to transport freshly-mixed concrete for longer distances without need of re-tempering at the job site. Sika® ViscoFlow-2020 works as a slump-retaining admixture, not as a conventional water-reducer, making it more user-friendly with a more predictable performance over time. This becomes a benefit in cases where time between concrete batching and concrete placement is inconsistent. Sika® ViscoFlow-2020 can be used as a stand-alone additive or in combination with any Sika® concrete admixture.

• Extended slump retention without excessive set retardation;
• Reduced or eliminated need for concrete re-tempering;
• “Flat” slump life performance;
• Better ability to optimize concrete mix designs, resulting in cost savings;
• Ability to use higher content of supplementary cementitious materials due to improved production consistency;
• Ability to adjust the slump retention accordingly to transportation time;
• Easy and simple adjustment of concrete slump-retention based on ambient temperatures;
• Improved concrete consistency and reduced rejection rates due to issues related to concrete re-tempering.
