Additionally itprovides ultra high water reduction and excellent flow characteristics.With its outstanding combination of workability time and strength developmentSika ® ViscoCrete ® -SF 18 is used for the following:• A wide range of applications where excellent workability and high strengthdevelopment are required• Concrete with ultra high water reduction (up to 30%)• High performance concretes• Self Compacting Concrete (SCC)Sika ® ViscoCrete ® -SF 18 is a powerful superplasticiser based on advanced technologywhich gives the following advantages:• High water reduction, resulting in high density, high strength and reducedpermeability• Extended workability in conjunction with subsequent fast strength development• Excellent plasticising effect, resulting in improved flow, placing and compactioncharacteristics• Reduced shrinkage during curing and reduced creep when hardened• Provides many opportunities for cost improvement e.g.:- Cement reduction- More economic mix design- Reduction of potential claims etc.Sika ® ViscoCrete ® -SF 18 does not contain chlorides or any other ingredients whichpromote the corrosion of steel. It is therefore suitable for use in reinforced andprestressed concrete structures.TestsApproval / Standards Conforms to the requirements of EN 934 - 2, Table 3.1 / 3.2.1 Sika® ViscoCrete®-SF 18 1/3
