UNIV®-NS is a mineral-based silica powder (SiO2 98%+) that enhances concrete strength with multiple properties including self-compacting ability, strength enhancement, heat dissipation, prevention of water seepage (leakages), and smooth surface finish. It meets all national and international standards for ready-mix concrete applications.
Reference Standard
- IS 516:2018 (Part 2/Sec 1)
- IS 4031:1988 Part 8
- IS 4926:2003
Area of Application
- High-grade concretes
- Ready Mix Plant (RMC)
- Precast work
- All types of concrete work
Benefits
- Crack Reduction: UNIV®-NS aids in preventing cracks, improving cohesion, and reducing maintenance costs in the long term.
- Compressive Strength: Demonstrates compressive strengths ranging from 12.1–14.5 MPa at 2 days, 19.1–23.8 MPa at 7 days, and 34.1–36.9 MPa at 28 days.
- Purity: Contains high levels of silica (95% to 99%) compared to regular sand, reducing impurities.
- Temperature Reduction: Can reduce temperatures via carbon reduction at 1600°C–2000°C to yield volatile silicon monoxide.
- Water Leakage Reduction: Some silica sands absorb moisture better than others, aiding in reducing water leakages.
- Time Saving: Offers quick setting time and smooth surface finish, reducing further surface treatment time.
- Long Durability: Allows for long-term use, reducing maintenance costs.
- Easy Application: Easy to mix in batches as needed.
- Eco-Friendly: Contains no fly ash or slag.

Limitations or Restrictions
- Avoid direct application to gypsum plaster or boards, fiber cement boards, drywall partitions, plywood, chipboard, particleboard, decorative laminates, resilient flooring, metal, plastic, deformable surfaces, or surfaces subject to vibrations.
- Not suitable for fixing artificial, nano, engineered stone, composites, or metal tiles.
How toApply: -
Surface Preparation
Prepare the surfaces before the UNIV®– NS application by removing oil, bond inhibiting agents, dirt, dust and laitance
The cleaning can be carried out with suitable methods like by using wire brush, water jetting,mopping, etc.
Mixing
UNIV®-NS requires 16% of Normal Water by weight of material (Example- 40kg Bag requires 7.0 to 8.0 Litre of Water)
Mix UNIV®-NS to the measured quantity of water using mechanical stirring for 2-3 minutes to ensure a consistent lump free mixture.
Curing
Due to Silica Base compound the temperature of bonding agent low & it gives fast curing, Its Required time for Settlement is 24Hr.
Water Curing is required for 2 to 3 time in day up to 7 days from application.
Precaution –safety
As per health & safety rules. Use safety accessories required to be used, would include:
a) Safety gloves
b) Safety goggles
c) Dust & nose mask
d) Helmet
In case of accidental contact with eyes of either dry or wet mix, immediately wash your hands; make sure your hands are clean and then wash your eyes with clean water and if required, seek medical assistance.
Avoid breathing dust.
