Sika® ViscoCrete®-4217 HE
Polycarboxylate water reducer engineered for high early strength concrete
Product Overview
Sika ViscoCrete-4217 HE is a high-performance superplasticizing admixture built on a modified polycarboxylate (PCE) chemistry that disperses cement particles far more effectively than conventional plasticizers. The result is concrete that flows freely at low water content, gains strength quickly in early hours and finishes denser and more durable. It suits floors, slabs, foundations, congested reinforcement, walls and columns, and performs reliably in ready-mix, self-compacting, precast, prestressed and pumped concrete. Producers value it where fast formwork turnover and early load-bearing capacity matter. Supplied by Space Arc Engineering, an authorized Sika project distributor in India, it gives concrete plants and contractors a dependable route to high-early-strength, low-shrinkage mixes. Dosage and compatibility should always follow the current Technical Data Sheet and on-site trials.
Features & Benefits
- Polycarboxylate dispersion mechanism unlocks substantial water reduction without sacrificing flow
- Accelerates early strength development for faster formwork stripping and quicker construction cycles
- Produces dense, low-permeability concrete that improves long-term durability
- Enhances cohesion and rheology, making mixes easier to place and finish
- Lowers drying shrinkage, reducing the risk of cracking in slabs and structural members
- Versatile across ready-mix, precast, prestressed, self-compacting and pumped concrete
Technical Highlights
| Coverage | Recommended dosage of 0.2-2.0% by weight of cementitious material; optimum rate set by trial mix (refer to TDS). |
| Strength | Improves early and ultimate compressive strength through water reduction and denser matrix; exact values depend on mix design (refer to TDS). |
| Performance | Light brown liquid, density ~1.13 kg/l at 25°C, pH ≥6, with strong dispersion and reduced drying shrinkage. |
| Application Conditions | Add to mixing water or to the mixer after 50-70% of water; minimum 60 seconds wet mixing recommended. |
| Packaging | Available in 255 kg drums or bulk supply. |
Applications
- High-early-strength precast and prestressed elements requiring rapid mould turnover
- Infrastructure foundations and bridge components with congested reinforcement
- Industrial floor slabs needing dense, low-shrinkage finishes
- Commercial high-rise walls and columns cast with pumped, flowing concrete
- Ready-mix and self-compacting concrete for fast-track residential projects

Frequently Asked Questions
What is Sika ViscoCrete-4217 HE used for?
It is a high-early-strength polycarboxylate superplasticizer used to make free-flowing, low-water concrete that gains strength quickly. Typical applications include precast, prestressed, ready-mix, self-compacting and pumped concrete for slabs, foundations, walls and columns.
What dosage of ViscoCrete-4217 HE should I use?
The general recommendation is 0.2-2.0% by weight of cementitious material, with the exact figure fixed by trial mixes. Higher dosages may be used with consultant approval. Always confirm against the current TDS.
Does ViscoCrete-4217 HE comply with Indian standards?
Yes, it is formulated to meet IS 9103 and ASTM C494 requirements for concrete admixtures. Refer to the TDS for the applicable admixture type classification.
How is it added to the concrete mix?
It can be added with the mixing water or dosed into the mixer after 50-70% of the water has been added. A minimum wet mixing time of about 60 seconds is recommended for proper dispersion.
