What Is Nanotechnology
What is Nanotechnology?
“Nanotechnology is the art and science of
manipulating matter at the nanoscale”

Nanotechnology is not a new science and it is
not a new technology.
Nanotechnology is an enabling technology that
allows us to develop materials with improved
or totally new properties
Nanotechnology is the use of very small
particles of material. A nanometer is a billionth
of a meter.
NANOTECHNOLOGY IN CONCRETE
Concrete is a mixture of cement, sand(fine
aggregate), coarse aggregate and water.
As concrete is most usable material in
construction industry it’s been require to improve
its quality.
 Nanotechnology can modify the molecular
structure of concrete material to improve the
material properties.

Introduction To Nano Materials
 Carbon Nano Tubes(CNT)
 NANO-SILICA
 TiO2
 TiO2 In Concrete:TiO2 is a white pigment and can be
used as an excellent reflective coating.
it is hydrophilic and therefore gives self cleaning
properties to surfaces to which it is applied.
Need For Nanotechnology In Steel..
• High Strength Steel Cables
• High strength bolts
• Temperature restriction
