SikaPlast®-771 KH combines different modes of actions.By absorption on the surface of the fines and keeping them apart while the hydration is in progress, SikaPlast®-771 KH effects the following concrete properties:

• Long slump keeping and high water reduction

• High flowability (considerably reduced placing and compacting work)

• Faster evolution of early strength development

• Workability can be maintained up to 4-6 hours (still depends on admixture dosage, cement type, temperature)

• Improved creep and shrinkage resistance characteristics
