Sikament®-2004 NS
Naphthalene-based superplasticizer and high-range water reducer
Product Overview
Sikament®-2004 NS is a high-range water-reducing superplasticizer based on modified naphthalene formaldehyde sulphonate. Added to the mix, it disperses cement particles so the same concrete flows freely at a much lower water content, or holds the water and gains workability for easier placing. The result is denser, stronger, more durable concrete with better surface finish and good consistency retention, even in hot weather. It suits free-flowing concrete in floors, slabs, foundations, walls, columns and pavements, and is used in high-performance, ready-mix, precast, prestressed and site-batched concrete. Conforming to IS 9103 and ASTM C494, it is supplied across India by Space Arc Engineering as an authorized Sika distributor, with dosage guidance for site and plant batching.
Features & Benefits
- Large water reduction lets you raise strength and density without losing workability
- Produces free-flowing concrete that places and compacts easily around dense reinforcement
- Improved consistency retention gives more time for transport and placing
- Better surface finish and cohesion reduce honeycombing and finishing effort
- Performs reliably in hot-weather concreting common across India
- Conforms to IS 9103 and ASTM C494 for straightforward specification
Technical Highlights
| Coverage | Recommended dosage is 0.5% to 2.0% by weight of cement, with higher rates possible on engineer approval; finalize by trial. |
| Strength | Higher strength and density follow from the reduced water-cement ratio; refer to TDS for figures. |
| Performance | Combines strong water reduction with improved consistency retention, durability and watertightness, including in hot weather. |
| Application Conditions | Add to the mix water or to the mixer after 50–70% of water; minimum 60-second wet mix. Store at +10°C to +40°C, away from frost and sun. |
| Packaging | Supplied as a dark brown liquid (~1.18 kg/l) in 275 kg drums or bulk; 12-month shelf life sealed. |
Applications
- Free-flowing floors, slabs and rafts in commercial and industrial buildings
- Foundations, walls and columns with congested reinforcement
- Ready-mix concrete supplied to large infrastructure sites
- Precast and prestressed elements needing high early density and finish
- Concrete pavements and hardstandings requiring durable, workable mixes

Frequently Asked Questions
What is Sikament-2004 NS?
It is a naphthalene-based superplasticizer (high-range water reducer) for concrete. It lets you either reduce water for higher strength and density or increase workability for free-flowing, easily placed concrete.
What is the dosage of Sikament-2004 NS?
The recommended dosage is 0.5% to 2.0% by weight of cement, with higher rates permitted on engineer approval. Optimal dosage should be confirmed by trial mixes for your materials.
Is Sikament-2004 NS suitable for hot-weather concreting?
Yes. It improves consistency retention and is suited to hot-weather conditions, helping maintain workability during transport and placing. Follow the TDS for retention times and mix design.
Does Sikament-2004 NS meet Indian standards?
It conforms to IS 9103-1999 and ASTM C494, so it can be specified confidently for structural and ready-mix concrete in India.
