Sika ViscoFlow®-903 X M
PCE superplasticizer engineered for extended slump retention without added retardation
Product Overview
Sika ViscoFlow®-903 X M is a polycarboxylate-ether (PCE) based superplasticizer built specifically to keep concrete flowing for longer without leaning on heavy retardation. Its tailored polymer chemistry disperses cement particles efficiently, so a single dose delivers high water reduction together with sustained slump-flow retention across long transit and placement windows. The admixture suits mixes from low to high water-cement ratios and performs well in hot or cold conditions where extended transportation time would otherwise cause early stiffening. By preserving rheology without delaying strength gain, it helps producers maintain pumpability, finish quality and durability while cutting drying shrinkage. Ready-mix plants, precast yards and large infrastructure contractors rely on it for predictable, defined workability periods. Space Arc Engineering, an authorized Sika distributor in India, supplies it for projects demanding consistent long-haul concrete.
Features & Benefits
- Maintains slump flow over extended haul and placement windows without extra retarder
- High-range water reduction improves strength development and packing density
- Reduced drying shrinkage supports more durable, crack-resistant concrete
- Stable rheology aids pumpability and a cleaner surface finish
- Effective across low and high water-cement ratio mix designs
- Suited to hot and cold weather concreting with long transport times
Technical Highlights
| Coverage | Recommended dosage 0.2-2.0% by weight of cementitious material; higher rates only with technical approval (refer to TDS). |
| Strength | High water reduction promotes enhanced strength development; project-specific values via trial mixes (refer to TDS). |
| Performance | Extends workability retention without delaying set, with improved dispersion and reduced drying shrinkage. |
| Application Conditions | Add to mixing water or to the mixer after 50-70% of water; minimum 60-second wet mix; never add to dry materials. |
| Packaging | Supplied in 255 kg drums or in bulk. |
Applications
- Long-distance ready-mix supply to highway and metro infrastructure sites
- Precast and prestressed elements requiring controlled, repeatable workability
- Mass-pour foundations and rafts in commercial high-rise construction
- Pumped concrete for tall residential towers needing retained flow
- Hot-weather industrial slab and pavement pours with extended transit

Frequently Asked Questions
What is Sika ViscoFlow-903 X M used for?
It is a PCE-based superplasticizer used to retain concrete slump and workability over long haul and placement times while still allowing high water reduction and good strength development. It is ideal for ready-mix supply, precast and large pours in hot conditions.
How does ViscoFlow-903 X M differ from a normal superplasticizer?
Conventional superplasticizers give a strong initial slump that fades quickly. ViscoFlow-903 X M is engineered for extended slump-flow retention without added retardation, so flow stays consistent across the transport and placing window.
What is the recommended dosage of Sika ViscoFlow-903 X M?
The recommended range is 0.2-2.0% by weight of cementitious material; higher dosages are possible with technical approval. Optimum dosage should be confirmed by trial mixes for your materials. Refer to the current TDS.
Does ViscoFlow-903 X M delay concrete strength gain?
No. It is designed to extend workability retention without significant retardation, so strength development proceeds normally. Verify performance with site trials and refer to the TDS for specifics.
