Nano concrete is concrete along with cement particles in the size range of 0 to 100nm either added later or included in to cent formulation. These small particles tend to fill up all nanopores and increase the quality of concrete drastically even with a small addition of 1% to 2% of cement weight.
A few properties of it are :
- Increased strength (70 to 100 MPa in 28 days)
- Increased durability because of lesser pores filled with water.
- Better workability of the concrete mix.
- Reduced shrinkage losses and drying shrinkage
