Nanoscience and Nanotechnology in Civil Engineering
INTRODUCTION TO NANOTECHNOLOGY AND
WHAT IS NANOTECHNOLOGY?
Nanotechnology is the design , characteristics,
production and application of structures, devices
and systems by controlling shape and size at
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
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.
NANOTECHNOLOGY IN CONCRETEConcrete 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
The mechanical behavior of
concrete materials depends on
phenomena that occur on a micro
and a Nano scale.
Sustainability of concrete
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
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
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
VERTICAL SCIENCE & ENGINEERING
Nano science is an
which means that it
involves concepts of
more than one discipline,
such as chemistry,
physics, etc. there are
other disciplines that are
materials science and
engineering which cover
at the same time
concepts of chemistry
