Sika® Plastiment® BV-40 is a powerful plasticiser which acts through several different mechanisms including surface adsorption separating the cementitious binder particles due to the electrokinetic potential. The following advantageous properties are achieved:

• Superior plasticising effect, resulting in improved flow, placing and compaction characteristics
• Keeps extended workability time with many difficult cements despite water reduction
• Water reduction, resulting in improved density, higher strength and reduced permeability

Sika® Plastiment® BV-40 does not contain chlorides or any other ingredients which promote corrosion of steel. It is therefore suitable for use in reinforced and prestressed concrete structures.
