Nanofine
Nanofine is specially produced from Granulated Blast Furnace Slag(GBS), Having an average particle size of about 4 microns.
Nanofine is used as a Supplementary cementitious material (SCM) replacing silica fumes and other fines, which are used for high-performance concrete.
Due to its chemical composition, it makes concrete more alkaline and retains its alkalinity, which protects the reinforced steel in concrete and mitigates corrosion.
A dense pore structure restricts the ingress of chloride and sulfate ions. Nanofne improves strength in concrete by increasing the secondary hydrated product resulting in improved strength
gain to achieve as high as an M-100 grade concrete.
It is used to produce high-grade concrete
from 60 and above.
- Low Water to Cement ratio.
- Improves durability.

- Ease of placement.
- Compaction without segregation.
- Replaces silica fumes.
- Conforms IS 16715 – 2018.
- Smooth and defect-free surface.
- Lighter color surface.
- Low carbon footprint.
- Environment resources conservation.
- Makes high-strength concrete with greater performance.
- High early strength and self-compacting concrete.
- High modulus of elasticity and abrasion resistance.
- Low heat of hydration and thermal cracking.
- Use for injection in cracking.
- Low permeability and diffusion.
