Education is not an act of acquiring knowledge but learning a skill to lead life and
forming one’s personality. This is an ennobling process of growth. I can boldly say that we
have excelled in every initiative that we undertook and we have stood together in facing the
challenges in realizing quality education. Our Institution has been actively involved in
various activities that have brought to light the hidden talents of the college students and
faculty. I am happy to note that the Department of Civil Engineering is coming out with their
Annual Newsletter. The Newsletter is presenting a glimpse of the growth of the Department
on many fronts. I congratulate the department for their commitment towards the provision of
excellent all round education for our students. I also wish them to move forward with
confidence, pride and enthusiasm.
I am happy to know that the Department of Civil Engineering, Aarupadai Veedu Institute
of Technology of Vinayaka Missions Research Foundation is bring a newsletter of the Department.
I appreciate the department for such an initiative to provide a platform for communicating the
innovative ideas of the students and faculty members. News letter is an excellent platform for the
students to publish their success stories, innovative ideas and findings. They can also write about
the improvements, required in the curriculum and syllabus of the course and subjects the study.
The students and faculty members can take some interviews with their alumni about their
experiences and job opportunities and publish in the news letter for the benefit of the students.
Apart from the professional interest, every student and faculty will have literary interest and
capabilities like poem writing, comics writing and moral story writing. This will add value and
interest for the readers of the news letter. I congratulate the Department and the concerned staff
members and students for the efforts taken by them to bring out this news letter. I wish that the
news letter brings fruits to the student community and wish a grand success for their efforts.
I am delighted to know that Civil Engineering Department of AVIT is bringing out their
Annual News Letter showcasing their activities, initiatives and achievements in addition to
technical articles. Civil Engineering is one of the oldest recognized branches of engineering that,
even today for most of the old timers Engineer implicitly meant Civil Engineer. It could be
because all their activities could be visibly seen in the form of roads, buildings, bridges, dams,
airports etc. The other engineering disciplines may change with times in evolving, reshaping,
merging etc. but civil engineering will maintain its unique identity. In-spite of being the oldest
discipline, it is still evolving and many new developments are taking place, to make their
constructions less costly and affordable, environment friendly and more safer. Lot of research
activities are going on in the form of low cost housing, green buildings, constructions which can
withstand severe weather and natural calamities. I am happy that Department of Civil Engineering
at AVIT is keeping up with times by framing and teaching syllabus which includes current trends
and also carrying out research activities. The innate desire to bring this newsletter shows their
unique identity. I compliment the faculty of Civil Engineering Department for their initiative and
wish them all the best in all their future Endeavours. Dr. S.A.V. SATYA MURTY

Internet of Things (IoT) is a hot-topic on research. While IoT is in its peak with Communication and Infor-
mation Technology departments, it is still in its infancy with applications to Civil Engineering structures. The needs
of a changing society present new challenges for Civil Engineers, like how to reduce our environmental impact, and
the preservation of ageing infrastructure. The traditional way of construction, the known technologies, might not suc-
ceed always. What we need is a paradigm change towards new technologies. Here academics and practitioners, own-
ers and stakeholders need to take a step forward.
WHAT IS INTERNET OF THINGS (IOT) ? The internet of things (IoT) is the internetworking of physical devices, vehicles, buildings and other items which are
embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect
and exchange data. The Internet of Things (IoT) is transforming every facet of the building – how we inhabit them,
how we manage them, and even how we build them. There is a vast environment around today’s buildings, and no
part of the environment is unaffected.
APPLICATIONS IN CIVIL ENGINEERING
Though there are wide variety of applications of IOT in Civil Engineering, few applications are discussed below.
Collection of Datas
Data collection plays a vital and extensive role in construction. The emergence of the Industrial Internet of Things
(IoT) represents a significant shot in the arm for the civil engineering sector. The deployment of low-energy sensors
to monitor an infrastructure’s condition and environment allows for a vast range of data to be gathered remotely, be-
fore being aggregated and visualized.
Better coordination of activities IOT communication protocols helps project managers and construction workers to give process instructions quickly
and effectively, irrespective of whether they are at the construction site or not. The construction manager can set up
IoT machines, employ internet technologies, like computer devices or softwares to send and receive data, making the
workers to work effectively even under the control of the remote boss.
Better monitoring of supplies
Radio-frequency identification (RFID) system helps to identify deficiency or need of raw materials can be predicted
in advance by the site engineer. IoT softwares can be programmed to alert the necessary departments in the project
team when supplies are low and more orders should be made. This helps in preventing oversupply of materials and
also prevents delay in construction works due to shortage of construction materials.
Better Analysis and Tracking
The recent innovations in technology make it possible for the construction workers to accurately determine the num-
ber of workers needed for project, and how a particular machinery would function. With this, there would be no more
delay in planning since most processes will be automated, and even the cost of purchasing replacements for equip-
ments can be well managed.
For better Monitoring of devices The sensors embedded in machines help tracking it and sending data about its operations. This help improving the
routine maintenance activities, manage time and resources and yield better result as prompt notice about devices that
needed to be serviced, repaid or replaced with new one are given. Information regarding the amount of power or fuel
used by a device or equipment can also be obtained.
Augmented Reality
The internet of things technology also brings in augmented reality which makes it possible to program safety devices
with sensors. It can also stimulate real-world interactions, communicate, and process the collected data. These can be
controlled either through a touchpad or voice command system. At a construction site, a voice command is preferred
as workers are usually engaged in physical activities.
CONCLUSIONS
It doesn’t matter if you’re working on small or large tools equipment, the integration of IoT in the construction indus-
try means the building process is enhanced, instructions would be better processed to yield better results, there would
be proper and better analysis and recording, accidents can be better prevented and resources, both human resources
and material resources would be better managed. In coming years the concept of IoT in Smart City as well as Smart
dwelling will be adopted ubiquitously.

NON-DESTRUCTIVE DIAGNOSIS OF ARCHITECTURAL ELEMENTS
OF ANCIENT HISTORICAL BUILDINGS The methodology consists of the integrated sequential application of in situ proximal sensing
methodologies such as the 3D Terrestrial Laser Scanner for the 3D modelling of investigated
objects together with laboratory and in situ non-invasive multi-techniques acoustic data,
preceded by an accurate petrographical study of the investigated stone materials by optical and
scanning electron microscopy. The increasing necessity to integrate different types of
techniques in the safeguard of the Cultural Heritage is the result of the following two
interdependent factors: 1) The diagnostic process on the building stone materials of
monuments is increasingly focused on difficult targets in critical situations. In these cases, the
diagnosis using only one type of non-invasive technique may not be sufficient to investigate
the conservation status of the stone materials of the superficial and inner parts of the studied
structures 2) Recent technological and scientific developments in the field of non-invasive
diagnostic techniques for different types of materials favors and supports the acquisition,
processing and interpretation of huge multidisciplinary datasets.

STONE MASTIC ASPHALT in HIGHWAYS Stone Mastic asphalt (SMA), otherwise known as Stone Matrix Asphalt / Split Mastic
Asphalt, was developed in Germany in the mid of 1960's and it has spread throughout Europe and
across the world in 1980's and 1990's respectively. The excellent performances include resistant
to mechanical and temperature deformation, cracking, and particularly rutting, resistant to
weathering actions such as aging and low temperature cracking. Durability is excellent even
under slow moving heavy traffic. The textured surface increases skid resistance and provides
environmental and driving comfort by reduced noise level, and improved visibility in rainy days.
SMA provides a deformation resistant, durable, surfacing material, suitable for heavily trafficked
roads. SMA has a high coarse aggregate content that interlocks to form a stone skeleton that resist
permanent deformation. The stone skeleton is filled with mastic of bitumen and filler to which
fibres are added to provide adequate stability of bitumen and to prevent drainage of binder during
transport and placement. Typical SMA composition consists of 70−80% coarse aggregate,
8−12% filler, 6.0−7.0% binder, and 0.3 per cent fibre. The deformation resistant capacity of SMA
stems from a coarse stone skeleton providing more stone-on-stone contact than with conventional
dense graded asphalt (DGA) mixes. Improved binder durability is a result of higher bitumen
content, a thicker bitumen film and, lower air voids content. This high bitumen content also
improves of flexibility. Addition of a small quantity of cellulose or mineral fibre prevents
drainage of bitumen during transport and placement. The essential features, which are the coarse
aggregate skeleton and mastic composition, and the consequent surface texture and mixture
stability, are largely determined by the selection of aggregate grading and the type and proportion
of filler and binder.

VACCUM CONCRETE
Vacuum concrete is concrete in which the excess water is removed for improving concrete strength .The
water is removed by use of vacuum mats connected to a vacuum pump. Vacuum process of concreting enables to
meet this conflicting demand. This process helps a high strength. The concrete problem include the presence of ex-
cess pores and the water in it .This affects the strength, durability and workability of the concrete. This can be recti-
fied by vacuum concrete method .The method of removing the water in it is vacuum hydro extracting construction
method and it is operated with a vacuum mat, vacuum pump, water separator, filtering pad and screen board vibra-
tor .Review of paper shows that 5 to 25% of strength increased when compared with conventional concrete.
ARRANGEMENT OF VACUUM CONCRETE
LAYING OF VACUUM CONCRETE
Surface vibration is done by using double beams surface vibrator Vacuum dewatering is done by using vacuum pump , suction mat and filter pads.
Floating and troweling of the concrete is done by skin floating
ADVANTAGES
It removes the pores and excess water from the concrete
It reduces the shrinkage
Make low permeability and greater durability
DISADVANTAGES
Vacuum dewatering system is best suitable for floor dewatering

Structural analysis is mainly concerned with finding out the behaviour of a physical structure when
subjected to force. This action can be in the form of load due to the weight of things such as people,
furniture, wind, snow, etc. or some other kind of excitation such as an
earthquake, shaking of the ground due to a blast nearby, etc. In essence
all these loads are dynamic, including the self-weight of the structure
because at some point in time these loads were not there. The distinc-
tion is made between the dynamic and the static analysis on the basis of
whether the applied action has enough acceleration in comparison to the
structure's natural frequency. If a load is applied sufficiently slowly, the
inertia forces (Newton's first law of motion) can be ignored and the
analysis can be simplified as static analysis. Structural dynamics,
Therefore, type of structural analysis which covers the behaviour
of structures subjected to dynamic (actions having high acceleration)
loading. Dynamic loads include people, wind, waves, traf-
fic, earthquakes, and blasts. Any structure can be subjected to dynamic
loading. Dynamic analysis can be used to find dynamic displacements,
time history, and modal analysis.A dynamic analysis is also related to the inertia forces developed by a
structure when it is excited by means of dynamic loads applied suddenly (e.g., wind blasts, explosion,
earthquake).A static load is one which varies very slowly. A dynamic load is one which changes with
time fairly quickly in comparison to the structure's natural frequency. If it changes slowly, the struc-
ture's response may be determined with static analysis, but if it varies quickly (relative to the structure's
ability to respond), the response must be determined with a dynamic analysis. Dynamic analysis for
simple structures can be carried out manually, but for complex structures finite element analysis can be
used to calculate the mode shapes and frequencies.
MODAL ANALYSIS
A modal analysis calculates the frequency modes or natural frequencies of a given system, but not nec-
essarily its full-time history response to a given input.

NONDESTRUCTIVE TESTING USING SCHMIDT HAMMER
Mr. SIJO, FINAL YEAR CIVIL ENGINEERING
A Schmidt hammer, also known as a Swiss hammer or a rebound hammer, is a device
to measure the elastic properties or strength of concrete or rock, mainly surface hardness and
penetration resistance. Testing the compressive strength of a concrete cube using Schmidt ham-
mer It was invented by Ernst Schmidt, a Swiss engineer. The hammer measures the rebound of a
spring-loaded mass impacting against the surface of the sample. The test hammer will hit the con-
crete at a defined energy. Its rebound is dependent on the hardness of the concrete and is meas-
ured by the test equipment. By reference to the conversion chart, the rebound value can be used to
determine the compressive strength. When conducting the test the hammer should be held at right
angles to the surface which in turn should be flat and smooth. The rebound reading will be af-
fected by the orientation of the hammer, when used in a vertical position gravity will increase the
rebound distance of the mass and vice versa for a test conducted on a floor slab. The Schmidt
hammer is an arbitrary scale ranging from 10 to 100.
VR INTERACTIVE MODELS
Mr. B. SHIVANANTH THIRD YEAR CIVIL ENGINEERING
Virtual reality is a technology that allows users to explore and manipulate 3D interactive
environments in real time. VR is seen today as an integrating technology, with great potential for
communication between project participants, and most recently, as a tool for the support of
decision-making. The main aim of a research project, which is now in progress at the Department
of Civil Engineering of the Technical University of Lisbon, is to develop virtual models as tools
to support decision-making in the planning of construction management and maintenance. A first
prototype concerning the lighting system was developed. It integrates VR system and a computer
application implemented in Visual Basic (VB) language. The model allows the examination of
the physical model, visualizing, for each element modeled in 3D and linked to a database, the
corresponding technical information concerned with the wear and tear aspects of the material,
defined for that period of time. In addition, the analysis of solutions for maintenance work or
substitution and inherent cost are predicted, the results being obtained interactively and visibly in
the virtual environment itself.
THE HEART OF MY SOUL
Music, a food
For the heart,
I celebrate you,
Who really art thou?
A gent? Or a lady?
How awesome your melody is,
A rhythmic mood changer you are,
The soul of my heart, the heart of my soul
Who really art thou?
You really must be a lady,
They power over every man’s heart you have,
The true meaning of life you carve,
I can’t wait for you to love me like I do you,
Music, the soul of my heart, the heart of my soul Mr. PRADIP PURBEY

CONTACT LENS & THE ENVIRONMENT Most of the people depend on contact lenses to improve their vision. But these sight-
correcting devices don’t last forever – some of these devices are used for a short period of one
day and are disposed in various ways. Researches show that throwing these lenses down the
drain after usage will contribute to micro-plastic pollution in waterways. When the lenses are
washed down the drain, they ultimately end up in wastewater treatment plants. The team esti-
mates that anywhere from six to 10 metric tons of plastic lenses end up in wastewater in the U.S.
alone each year. Contact lenses tend to be denser than water, which means they sink, and this
could eventually pose a danger to aquatic life, especially bottom feeders that may ingest the
contact lenses. Ms. REEMA SINGH, THIRD YEAR CIVIL DEPARTMENT
HISTORY OF CONCRETE
The Romans first invented what today we call hydraulic cement based concrete. They built numerous concrete structures, including the Pantheon in Rome, one of
the finest examples of Roman architecture that survives to this day, which
has a 42-meter-diameter dome made of poured concrete. The name con-
crete comes from the Latin "concretus", which means to grow together. In
our world today, concrete has become ubiquitous, and in fact it is hard to
imagine modern life without it. About five billion tonnes of concrete are
used around the world each year. The cement used mostly in today's con-
crete is called portland cement. The process to produce portland cement
was invented by Joseph Aspdin in the early 1800's in England. The name
portland may have been originally a marketing ploy, as portland building
stone was very popular in England at that time.

COMPOSTING
Composting is an aerobic method of decomposing organic
solid wastes. It can therefore be used to recycle organic
material. The process involves decomposition of organic
material into a humus-like material, known as compost, which
is a good fertilizer for plants. Composting requires the
following three components: human management, aerobic
conditions, development of internal biological heat.
PHASES OF COMPOSTING Under ideal conditions,
composting proceeds through three major phases:
An initial, mesophilic phase, in which the decomposition is
carried out under moderate temperatures by mesophilic
microorganisms.
As the temperature rises, a second, thermophilic phase starts,
in which the decomposition is carried out by various
thermophilic bacteria under high temperatures.
As the supply of high-energy compounds dwindles, the tem-
perature starts to decrease, and the mesophiles once again pre-
dominate in the maturation phase.

PLASTICS AND PENS??
Plastic, a well known pollutant is
let out into the environment by
us, literates. By the usage of
these ball point pens, gel pens
and these cartridge ink pens we
educated citizens of this world
pollute the environment.
Alternatives: Use Refillable ink
