Sika® Plastiment® BV-40 is a versatile and economical concrete plasticiser with set retarding properties.
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.
