Sika® Plastiment® VZ-1
High-efficiency chloride-free set retarder with a wide dosage range
Product Overview
Sika® Plastiment® VZ-1 is a highly efficient, chloride-free set-retarding concrete admixture based on a poly-hydroxyl compound. It delays the initial set of concrete so that workability is retained through long transport, large continuous pours and placement in elevated temperatures, helping contractors avoid cold joints and gain more time for compaction and finishing. Its broad dosage range gives plants flexibility to dial in the exact retardation a mix and climate demand. Once the extended dormant phase passes, the concrete hardens normally and can reach increased ultimate strengths, while the chloride-free formulation protects embedded reinforcement against corrosion. It disperses readily into the mixing water or the mixer and is compatible with all cement types, making it a practical choice for ready-mix operations. Space Arc Engineering, an authorized Sika distributor in India, supplies Plastiment VZ-1 for hot-climate concreting.
Features & Benefits
- Highly efficient retardation with a wide, adjustable dosage range
- Chloride-free, protecting embedded reinforcement from corrosion
- Keeps concrete workable through long hauls and hot-weather pours
- Helps prevent cold joints on large continuous placements
- Normal hardening with potential for higher ultimate strengths
- Compatible with all cement types and easy to dose
Technical Highlights
| Coverage | Recommended dosage 0.20-0.6% by weight of cement; optimum rate set by trial mixes (refer to TDS). |
| Strength | Permits increased ultimate strength after the retarded set; confirm by trial mixes (refer to TDS). |
| Performance | Delivers efficient set delay and slump-loss control, then normal strength gain. |
| Application Conditions | Add to the mixing water or directly to the mixer; suitable for all cements; trial-test locally. |
| Packaging | Supplied in 255 kg bulk packs. |
Applications
- Ready-mix concrete dispatched over long distances in hot weather
- Mass foundations and rafts requiring extended placing windows
- Infrastructure and bridge pours where cold joints must be avoided
- Large commercial substructures cast at high ambient temperatures
- Industrial slabs needing flexible, dial-in retardation control

Frequently Asked Questions
What is Sika Plastiment VZ-1 used for?
It is a highly efficient chloride-free set retarder used to extend concrete workability in hot weather and on large pours, preventing cold joints while still allowing normal hardening and high ultimate strength.
What dosage range does Plastiment VZ-1 offer?
It is recommended at 0.20-0.6% by weight of cement, a wide range that lets producers tune retardation to the mix and climate. Set the optimum rate by trial mixes and refer to the TDS.
How is Plastiment VZ-1 different from Plastiment VZ?
Both are chloride-free poly-hydroxyl retarders. VZ-1 is positioned as a highly efficient variant with a broader dosage range, giving more flexibility to fine-tune set delay. Confirm the right grade for your mix with the TDS.
Is Plastiment VZ-1 compatible with all cements?
Yes. It can be dosed into the mixing water or the mixer and is compatible with all cement types. Always run trial mixes with your local materials.
