1. INTRODUCTION TO NANOTECHNOLOGY AND
NANOSCIENCE

2. WHAT IS NANOTECHNOLOGY?
Nanotechnology is the design , characteristics,
production and application of structures, devices
and systems by controlling shape and size at
nanometric scale.

3. Nanotechnology in construction:
The construction business will inevitably be a beneficiary
of this nanotechnology.
In fact it already is in the fields of concrete, steel, glass and
many more.
Concrete is stronger, more durable and
more easily laced;
Steel is made tougher;
Glass is self-cleaning.
Pains are made more insulating and water repelling.

4. NANOTECHNOLOGY IN CONCRETEConcrete is a mixture of cement,
sand (fine aggregate )
coarse aggregate and water
As concrete is most usable material
in construction in
Industry it’s been require to improve
its quality.
The mechanical behavior of
concrete materials depends on
phenomena that occur on a micro
and a Nano scale.

5. Bulk properties
Mechanical performance,
Volume stability,
Durability,
Sustainability of concrete
 Nanotechnology can:
modify the molecular
structure of concrete
material to improve the
material’s properties as
shown in the chart.
 Nano-concrete is defined
as “A concrete made with
Portland cement particles
that are less than 500
Nano-meters as the
cementing agent“.

6. Nanotechnology and steel:

7. Need For Nanotechnology In Steel..
 fatigue is a significant issue that can lead to the
structural failure of steel subject to cyclic loading, such
as in bridges or towers.
This can happen at stresses significantly lower than
the yield stress of the material and lead to significant
shortening of useful life of the structure.
Advancements in this technology would lead to
increased safety, less need for monitoring and more
efficient materials use in construction prone to fatigue
issues.

8. Definition of Nano science:
Nano science is an emerging area of
science which concerns itself with
the study of materials that have very,
very small dimensions.
It can’t really be called chemistry,
physics or biology; all sorts of
scientists are studying very small
things in order to better understand
our would.

9. VERTICAL SCIENCE & ENGINEERING
DISCIPLINES
Nano science is an
interdisciplinary science
which means that it
involves concepts of
more than one discipline,
such as chemistry,
physics, etc. there are
other disciplines that are
inherently
interdisciplinary, like
materials science and
engineering which cover
at the same time
concepts of chemistry
and physics.
