SikaPlast®-355 X
PCE superplasticizer engineered for high water reduction in concrete
Product Overview
SikaPlast®-355 X is a high-efficiency superplasticizer based on modified polycarboxylate (PCE) chemistry, developed for concrete that demands a high degree of water reduction. By improving cement dispersion, it lets producers lower water content while retaining flow, resulting in concrete with greater density, higher strength and better compaction. It is comparatively forgiving of variations in aggregate gradation and cement type, supporting consistent batching where raw materials are not uniform. Typical applications include ready-mixed concrete, high-water-reduction mixes and projects needing enhanced workability. It serves RMC plants, infrastructure and commercial contractors, and precast operations seeking dependable, high-grade output. Space Arc Engineering, an Authorized Project Distributor of Sika in India, supplies SikaPlast®-355 X along with mix-design support to help customers reach target slump and strength efficiently.
Features & Benefits
- Strong water reduction for improved density and compressive strength
- Less sensitive to differences in aggregates and cement types
- Efficient at lower dosage rates, aiding cost control
- Extended workability so concrete remains placeable as strength develops
- Excellent flow and compaction characteristics for quality finishes
- Complies with IS 9103 and ASTM C494
Technical Highlights
| Coverage | Recommended dosage of 0.2% to 2.0% by weight of cement, with higher rates only on engineer approval; confirm via trials — refer to TDS. |
| Strength | Enables higher density and compressive strength through reduced water content; exact figures vary by mix — refer to TDS. |
| Performance | Offers extended workability with continued strength development and superior flow and compaction. |
| Application Conditions | Add to mixing water or to the mixer after 50–70% of water is in; recommended minimum wet mixing time of 60 seconds. Store at +10°C to +40°C, protected from sunlight and frost. |
| Packaging | Supplied in 255 kg HDPE carboys or by bulk tanker. |
Applications
- Ready-mix supply for commercial and high-rise construction
- Bridges, viaducts and other infrastructure requiring durable concrete
- Industrial flooring, foundations and water-resistant structures
- Precast and prestressed elements needing controlled workability
- Residential structural pours where high water reduction improves quality

Frequently Asked Questions
What makes SikaPlast®-355 X different?
It is a PCE superplasticizer formulated for a high degree of water reduction, which produces denser, stronger concrete while keeping the mix workable for placing and compaction.
What is the correct dosage for SikaPlast®-355 X?
Use 0.2% to 2.0% by weight of cement, with the optimum set by site trials. Dosages above the range require engineer approval — always check the current TDS.
When should SikaPlast®-355 X be added to the mix?
Add it to the mixing water, or into the mixer once 50–70% of the water has been added, and allow a minimum wet mixing time of about 60 seconds for full dispersion.
Is SikaPlast®-355 X suitable for variable raw materials?
Yes. It is designed to be less sensitive to changes in aggregates and cement type, which helps maintain consistent concrete from batch to batch at RMC plants.
