Sika ViscoFlow®-50 H
PCE superplasticizer for extended slump retention without extra retardation
Product Overview
Sika ViscoFlow®-50 H is a superplasticizer based on an aqueous solution of modified polycarboxylate (PCE). It is formulated to give significantly extended slump-flow retention without adding extra retardation, so concrete stays workable through long transport and placing times while early strength is not held back. It improves cement dispersion and rheology, supports strength development, reduces drying shrinkage and improves durability. The admixture suits ready-mix and site concrete across high and low water-cement ratios and is well suited to hot or cold weather with extended haul distances. Dosed between 0.2% and 2.0% of cementitious content, it complies with IS 9103 and ASTM C494 Type G. Space Arc Engineering supplies Sika ViscoFlow®-50 H across India as an authorized Sika distributor with mix-design support.
Features & Benefits

- Ideal for long transit and hot-weather concreting
- Reduces drying shrinkage and improves long-term durability
- Complies with IS 9103 and ASTM C494 Type G
Technical Highlights
| Coverage | Recommended dosage is 0.2% to 2.0% by weight of cementitious material, with higher doses on consultant approval. |
| Strength | Supports strength development while retaining workability; refer to TDS for strength data. |
| Performance | Delivers significantly enhanced slump-flow retention without additional retardation. |
| Application Conditions | Store and use between +10°C and +40°C; protect from direct sunlight and frost. |
| Packaging | Light brown to light yellowish hazy liquid; density about 1.09 kg/l, supplied in 255 kg drums or bulk. |
Applications
- Ready-mix concrete with long haul distances to site
- Hot-weather concreting where workability must be preserved
- High-rise and infrastructure pours needing extended placing time
- Large industrial slabs and rafts requiring constant flow
- Pumped commercial concrete where slump life is critical

Frequently Asked Questions
What does Sika ViscoFlow®-50 H do?
It is a PCE superplasticizer that gives significantly enhanced slump-flow retention without adding extra retardation, keeping concrete workable for long transport and placing times while supporting early strength.
What is the recommended dosage?
The recommended dosage is 0.2% to 2.0% by weight of cementitious material; higher dosages are possible with client or consultant approval. Always optimise dosage through trial mixes and refer to the TDS.
When should I use ViscoFlow®-50 H over a standard superplasticizer?
Choose it when long workability retention is needed, such as long haul distances or hot-weather concreting, and where you want to extend slump life without the additional set retardation that retarders cause.
Which standards does it meet?
Sika ViscoFlow®-50 H complies with IS 9103 and ASTM C494 Type G. It has a density of about 1.09 kg/l at 25°C and a pH of at least 6. Refer to the TDS for full data.
