Description
Sika® Plastiment® BV-40
Sika® Plastiment® BV-40 is a plasticiser for concrete and mortar based on modified lignosulfonates.
- 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.

Chloride free – does not attack reinforcement
Up to 12%, water reduction is possible
Uses:
Exposed surfaces are important
Maximum performance is desired
Placing conditions are difficult
Poor quality aggregates are found
Pre-cast elements are produced
Piling
Dosage:
0.2 to 0.8% by weight of cement. For more demanding situations use 0.5%. Plastiment -BV/40 is compatible with all types of Portland cement including Sulphate Resistant Cement (SRC). Actual dosage to be finalized on the basis of site trials.
Dispensing:
It should be dispensed directly into the mixing water prior to itsaddition to the wet concrete. When accidental overdosing occurs, Plastiment -BV/40 does not entrain excessive amount of air and does not effect the ultimate strength, only the setting time is extended.
Cleaning of Tools:
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
