I am a researcher in nanotechnology and its uses in construction fields. In simple words,” The technology which works with nanoscale is called nanotechnology”. In Civil engineering, if we can work on nanoscale, i.e. 0 to 10 nanometer, and able to change the molecular properties of cement, then that modified cement concrete is called nano-engineered cement concrete. Nowadays, it is possible to alter the cement properties according to our use.
Nanotechnology is one of the most active research which has vast app’s in almost all the fields.
As concrete is most usable material in constn industry its been read to improve its quality.
Improving concrete properties by addition of Nano particles have shown remarkable development than regular concrete.
Why nanotechnology for concrete?
Nano Concrete :-
Nano concrete is a form of concrete that contains portland cement particles that are not greater than 100μm and particles of silica not greater than 500μm, which fills voids that would otherwise occur in normal concrete, thereby substantially increasing the materials strength. It is the product of high-energy mixing of sand, water and cement.
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 :
