Sikament®-4101 NS
Water-reducing plasticizing admixture for workable, cohesive concrete
Product Overview
Sikament®-4101 NS is a water-reducing plasticizing concrete admixture based on modified naphthalene formaldehyde sulphonate. It deflocculates cement to give free-flowing, uniformly cohesive concrete that is easy to place and finish, while holding workability over time so transport and placing are less rushed. Used to reduce water, it raises strength, density, durability and watertightness and improves surface finish, with good resistance to segregation. It suits floors, slabs, foundations, reinforced members, walls, columns and pavements across ready-mix, precast and site-batched concrete. Conforming to IS 9103 and ASTM C494, and effective in hot weather, it is distributed across India by Space Arc Engineering as an authorized Sika partner, with support on dosage and trial mixes.
Features & Benefits
- Produces free-flowing yet cohesive concrete that resists segregation
- Enhanced workability retention eases transport and placing on busy sites
- Water reduction lifts strength, density and durability of the hardened concrete
- Improves surface finish, reducing remedial work after striking formwork
- Increases watertightness for more durable structures
- Reliable in hot-weather concreting and compliant with IS 9103 and ASTM C494
Technical Highlights
| Coverage | Recommended dosage is 0.5% to 2.0% by weight of cement; higher rates available on engineer approval, finalized via site trials. |
| Strength | Lower water-cement ratio supports higher strength and density; refer to TDS for project figures. |
| Performance | Delivers cohesive, free-flowing concrete with strong consistence retention, durability and improved finish. |
| Application Conditions | Add to mix water or to the mixer after 50–70% of water; minimum 60-second wet mix. Store +10°C to +40°C, away from sun and frost. |
| Packaging | Dark brown liquid (~1.17 kg/l, pH ≥6) in 275 kg containers or bulk; 12-month shelf life sealed. |
Applications
- Reinforced floors, slabs and foundations in residential and commercial buildings
- Walls and columns where a cohesive, easily finished mix is needed
- Ready-mix concrete delivered to medium and large projects
- Precast elements requiring good finish and dimensional quality
- Concrete pavements and pours needing extended workability
