Sika® ViscoCrete® ACE 8481
High range water reducer / superplasticizer
Sika® ViscoCrete® ACE 8481is a concrete admixture used as high range water reducer or superplasticizer. It is optimized for applications where the time between concrete mixing and placement is short, such as in precast concrete production. In this instance, the workability life of the concrete is optimized to give a balance between maintaining the workability while still enabling the early onset of the strength development process. The unique molecular configuration of the Product enables rapid cement hydration. Robustness and controlled workability retention are distinct features of the precast concrete produced with this Product.
- Enables concrete mixes with low water-cement ratio and eco-friendly, CO2-reduced mix designs
- Improves flowability
- Enables low-energy placing and compacting
- Enhances robustness and consistency in concrete quality with low stickiness
- Improves surface finishing
- Achieves high early strengths
- Eliminates or minimizes heat curing
- Increases productivity, reduces cycle time
- Promotes high density and high final strength
- Improves surface appearance and durability of concrete
- Reduces shrinkage, creep, and water permeability
- Free of chlorides, low alkali content
- Suitable for use in reinforced and pre-stressed concrete
- If used in conjunction with Sika®Rapid® concept, cycle times can be further reduced, and temperature curing regimes can be further reduced or even eliminated
