Workability Retaining Admixture
Sika ViscoFlow 2020 is a workability retaining admixture to extend the slump life of concrete without significantly delaying its set time and reducing its early age strength.
Sika® ViscoFlow®-2020 can be used in conventional, high slump, and Self Consolidating Concrete mixes, for precast/prestress, ready mix, or in any application when extended concrete plasticity without retardation is required. Sika® ViscoFlow®-2020 does not extend slump life through slowing down hydration process of cement.
Characteristics and Advantages
Use of Sika® ViscoFlow®-2020 offers the following benefits to a concrete producer:
■ Extended slump retention without excessive retardation.
■ Reduce or eliminate the 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.
Sika® ViscoFlow®-2020 is available in 55 gallon drum (208 liter), 275 gallon totes (1040 liters)and bulk delivery.
