Sika® ViscoCrete®-5138
High-range PCE superplasticizer for workable, high-strength concrete
Product Overview
Sika ViscoCrete-5138 is a high-performance superplasticizing admixture formulated from a modified polycarboxylate base to create free-flowing concrete with excellent water reduction and workability retention. Its advanced dispersion action separates cement particles so mixes flow and self-level at reduced water content, then harden into dense, durable, high-strength concrete with lower drying shrinkage. The admixture is well matched to floors, slabs and foundations, slender reinforced sections, walls and columns, and to high-performance, high-strength, ready-mix, self-compacting and pumped concrete. Space Arc Engineering, an authorized Sika distributor in India, supplies ViscoCrete-5138 to ready-mix producers and contractors who need consistent flow over time without compromising strength. As with all admixtures, dosage and compatibility should be validated by trial and the current Technical Data Sheet.
Features & Benefits
- Very high water reduction for high-strength, low-permeability concrete
- Sustained workability retention keeps mixes placeable during transport and handling
- Free-flowing rheology improves placing, compaction and surface finish
- Denser matrix enhances durability against aggressive exposure
- Reduced drying shrinkage lowers the likelihood of cracking
- Suited to self-compacting and pumped concrete in complex pours
Technical Highlights
| Coverage | Recommended dosage 0.2-2.0% by weight of cementitious material; higher rates only with consultant approval (refer to TDS). |
| Strength | Delivers high-strength concrete through strong water reduction and dense microstructure; values depend on mix design (refer to TDS). |
| Performance | Light brown liquid, density ~1.13 at 25°C, pH ≥6, providing free flow with workability retention. |
| Application Conditions | Add to mixing water or to the mixer after 50-70% of water, not onto dry aggregate; minimum 60 seconds wet mixing. |
| Packaging | Available in 255 kg drums or bulk. |
Applications
- High-strength concrete for towers, transfer slabs and core walls
- Self-compacting concrete in slender, densely reinforced members
- Ready-mix supply requiring reliable workability over longer haul distances
- Infrastructure foundations and water-retaining structures needing low permeability
- Pumped concrete for high-rise and large-volume commercial pours

Frequently Asked Questions
What is Sika ViscoCrete-5138?
It is a high-performance, polycarboxylate-based superplasticizer (high-range water reducer) that creates free-flowing, high-strength concrete with very high water reduction and good workability retention.
Is ViscoCrete-5138 suitable for self-compacting concrete?
Yes. Its flow characteristics and water reduction make it appropriate for self-compacting and high-performance concrete, with mix stability confirmed by trial.
How much ViscoCrete-5138 should be added?
The typical dosage is 0.2-2.0% by weight of cementitious material. Higher dosages are possible with consultant approval. Always check the current TDS for your mix.
Where in the batching sequence is it dosed?
Add it with the mixing water or to the mixer after 50-70% of the water has been introduced. It should not be added directly onto dry aggregate, and a minimum 60-second wet mix is recommended.
