Application of Nano Technology in Civil Engineering Construction MaterialsJournal For Research
There are many technologies whose applications are widely used in branch of civil engineering. There are both advantages and disadvantages of such technologies. But by using Nanotechnology the performance of material can be enhanced .Nanotechnology deals with understanding and controlling matter, atoms and molecules in the range of 0.1–100 nm (10-9 m). It creates materials, devices, and systems with new properties and functions. Nanoparticles have more surface area relative to their volume, making them useful in energy storage and for making composite materials. Nano materials are also able to be combined with biological materials, producing new structures that have properties of both types of materials. The role of nanotechnology in the infrastructure systems has the potential to set the civil engineering on a different height and widen the vision of civil engineering.
This powerpoint presentation covers the role of Nanotechnology in Civil Engineering materials, future challenge and direction, impact of nano technology in civil engineering, the merits & demerits of nanotechnology.

Experimental Study on Partial Replacement of Cement with Nano Silica in the C...ijtsrd
The main objective of this work is to study the mechanical strength and durability of the concrete when the particular cement dosage in concrete in replaced with Nano silica powder. However it is expected that the use of Nano-silica in concrete improve the strength properties of concrete. Also it is an attempt made to develop the concrete using Nano sized particles as a partial replacement of cement, which satisfies the various structural properties of concrete like compressive strength and tensile strength. It is expected that the final outcome of the project will have an overall beneficial effect on the utility of Nano-silica concrete in the field of civil engineering construction work.

Effect on Concrete by Partial Replacement of Cement by Colloidal Nano Alumina...IJCMESJOURNAL
Nanotechnology is a optimistic field in terms of environmental improvements including energy savings and reduced reliability on non-renewable resources, as well as reduced waste, toxicity and carbon emissions. Alumina component reacts with calcium hydroxide produced from the hydration of calcium silicates. The rate of the pozzolanic reaction is proportional to the amount of surface area available for reaction. Therefore, it is possible to add nano- Alumina of a high purity and a high Blaine fineness value in order to improve the characteristics of cement mortars The Aim of this project is to devlope the nano concrete and to study the effects of nano alumina on the properties of concrete. In this investigation the cement is replaced by 10% Fly-ash and Alumina nanoparticles of different proportion i.e 0.5%, 1%, 1.5%, 2.0%, 2.5% & 3% in M40 grade of concrete. It is observed that workability decreased with replacement of cement. The compressive strength of nano concrete casted by partially replacement of 10% fly ash & 2% & 2.5% colloidal nano alumina , increased over conventional concrete about 18.03%, 14.28% for 3 days and 12.7%, 11.27% for 7 days and 4.17% , 2.07% for 28 days. The Split Tensile strength of this concrete increases with 5.73% and 9.16% respectively over conventional concrete for the replacement 1.5% and 2%. Flexural strength of this concrete increases with 13.05% and 26.65% over conventional concrete for the replacement 2% and 2.5%.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Abstract
In this article, use of nanotechnology in building materials on behalf of a range of civil engineering mechanism
is discussed. In view of the fact that the use of nanotechnology controls the topic at the minute level, the
properties of matter are sincerely affected. Strength, durability and other properties of materials are dramatically
affected under a scale of nano meter(10-9m).This article as well reveals how the use of nano technology makes
concrete more stronger, durable and more easily placed. Different types of nano materials used are discussed
with its wide applications. The properties like self-sensing, self- rehabilitation, self-structural health monitoring,
self-vibration damping, self-cleaning and self-healing are studied. Following this the analysis were carried out in
ductile structural composites along with its improved properties, low repairs coatings, better properties of
cementitious materials, reduction of the thermal transfer rate of fire retardant and insulation, various
nanosensors, smart materials, intellectual construction technology.
Keywords: Civil Infrastructure Application, Nanotechnology properties.
I. INTRODUCTION
Nanotechnology is the use of very small
particles of material either by themselves or by their
manipulation to create new large scale materials.
Nanotechnology is not a new science and it is not a
new technology, it is rather an extension of the
sciences and technologies that have already been in
development for many years. Nanotechnology is the
re-engineering of materials by controlling the matter
at the atomic level. The key in nanotechnology is the
size of particles because the properties of materials
are dramatically affected under a scale of nano meter
[10-9 meter]. Further, as particles become nano-sized
the proportion of atoms on the surface increases
relative to those inside and this leads to novel
properties. Concrete is stronger, more durable and
more easily placed, steel tougher and glass self-
cleaning. Increased strength and durability are also a
part of the drive to reduce the environmental
footprint of the built environment by the efficient use
of resources.
II. Nanotechnology
Nanotechnology is the understanding and
manages of matter at dimension of approximately 1
to 100 nanometers; everyplace unique phenomena
enable novel applications.”Encompassing nanoscale
science, engineering and technology, nanotechnology
involves imaging, measuring, modeling, and
manipulating matter at this length scale.
Nanotechnology, shortened to “nanotech”, is the
study of the controlling of matter on an atomic and
molecular scale. Generally nanotechnology deals
with structures sized between 1 to 100 nanometer in
at least one dimension and involve developing
materials or devices within that size.
III. Uses of Nanotechnology in Civil
infrastructure
Nanotechnology can be used for plan and
construction processes in many areas ever since
nanotechnology generates products have many only
one of its kind characteristics. These characteristics
can, again, considerably fix present creation
tribulations, and may adjust the requirement and
associations of construction process.Some of their
applications are examine in detail below.
IV. Concrete
Concrete is one of the most common and
widely used manufacture materials. Nanotechnology
is widely used in studying its properties like
hydration reaction, alkali silicate reaction (ASR) and
fly ash reactivity. Alkali silicate reaction is caused
due to alkali content of cement and silica present in
reactive aggregates like chert. The use of pozzolona
in the concrete mix as a partial cement replacement
can reduce the likelihood of ASR occurring as they
reduce the alkalinity of a pore fluid. Fly ash not only
improves concrete durability, strength and,
importantly for sustainability, reduces the
requirement for cement, however, the curing process
of such concrete is slowed down due to the addition
of fly ash and early stage strength is also low in
comparison to normal concrete.
Addition of Nano-silica leads to the
densifying of the micro and nanostructure resulting in
improved mechanical properties. With the addition of

nano-SiO2 part of the cement is replaced but the
density and strength of the fly-ash concrete improves
particularly in the early stages. For concrete
containing large volume fly ash, at early age it can
improve pore size distribution by filling the pores
between large fly ash and cement particles at Nano
scale.

The coatings incorporate certain Nano
particles or Nano layers have been developed for
certain purpose including: protective or anti-
corrosion coatings for mechanism; self-cleaning,
thermal control, energy saving, anti-reflection
coatings for glass/windows; easy-to-clean,
antibacterial coatings for work surfaces; and more
durable paints and anti-graffiti coating for buildings
and structures.. This coating works in two stages.
First, using a „photocatalytic‟ process, nanosized
TiO2 particles in the coating react with ultra-violet
rays from natural daylight to break down and
disintegrate organic dirt. Secondly, the surface
coating is hydrophilic, which lets rainwater spread
evenly over the surface and „sheet‟ down the glass to
wash the loosened dirt away. It can therefore reduce
airborne pollutants when applied to outdoor surfaces.
Coating of 7000 m2
of road surface with such a
material in Milan in 2002 has led to a 60% reduction
in nitrogen oxides concentration at street level [22].
Research has also demonstrated that bimetallic Nano
particles, such as Fe/Pd, Fe/Ag, or Zn/Pd, can serve
as potent reductants and catalysts for a large variety
of environmental contaminants [11].

glass coated with 10 nm Au nanoparticles. The Au
nanoparticles are spherical and nearly 10 nm in
diameter.
VI. Glass
Fire-protective glass is another application
of nanotechnology. This is achieve by using a clear in
tumescent layer sandwiched between glass panel (an
interlayer) formed of fumed silica (SiO2)
nanoparticles which turns into a rigid and opaque fire
shield when heated. The electro chromic coatings are
being urbanized that react to changes in applied
voltage by using a tungsten oxide layer; thereby
becoming more opaque at the touch of a button.
Because of the hydrophobic properties of TiO2, it can
be applied in antifogging coatings or in self-cleaning
windows [1]. Nano-TiO2 coatings can also be applied
to building exteriors to prevent sticking of pollutants,
and thus reduce a facility‟s

VII. Steel
Steel has been widely available since the
second industrial revolution in the late part of the
19th and early part of the 20th Century and has
played a major part in the construction industry since
that time. 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 a significant
shortening of useful life of the structure. The current
design philosophy entails one or more of three
limiting measures: a design based on a dramatic
reduction in the allowable stress, a shortened
allowable service life or the need for a regular
inspection regime. Stress risers are responsible for
initiating cracks from which fatigue failure results
and research has shown that the addition of copper
nanoparticles reduces the surface unevenness of steel
which then limits the number of stress risers and
hence fatigue cracking. Surface of the stainless steel
after electro deposition of palladium nanoparticles
at low and high magnifications are shown.

VIII. CONCLUSION
Nanotechnology offer infinite amounts of
improvement in the civil engineering field. It has help
improve the quality of and solved many issue with
building materials such as concrete and steel. The use
of nanotechnology has also helped formed more
efficient also sustainable materials such as self-
cleaning and self-repairing concrete and window. The
use of coatings made from nanotechnology helps get
better fire-resistance, corrosion protection, insulation,
and innumerable other applications. Nanotechnology
can even help improve the quality and availability of
water. As a expected future civil engineer, this type
of technology is of greatest importance to me as I
will have to work with nanotechnology in my future.
When looking at all of these innovations and
improvements upon construction and environmental
areas, it can be clearly observed that nanotechnology
is of especially important to the field of civil
engineering and requirements to be bring into the
engineering program of study at school.
Nanotechnology is important to the future and
improvement of civil engineering; on the other hand
it cannot contribute to the field if it is not skilled on a
wider level as well as to every aspiring civil engineer.
