Sika ViscoCrete-5520 is a polycarboxylate based high range superplasticizer for concrete and mortar. Used for the production of site batched and ready mix concrete with extended slump retention, high water reduction and high strength development of concrete mixes.
- Strong self compacting behaviour, therefore suitable for the production of self compacting concrete (S.C.C)
- Extremely high water reduction (resulting in high density and strengths)
- Excellent flowability (resulting in highly reduced placing and compacting efforts)
- Improved shrinkage and creep behaviour
- Reduced rate of carbonation of the concrete
