UTILIZATION OF C&D WASTES AS RECYCLED AGGREGATES IN CONCRETE
Adithya P, IV Year B.E. (Civil) - (Summer internship program IIT Khargpur)
Abstract: Use of natural resources in the construction industry is substantially large and these
resources are depleting very fast, posing a threat of getting exhausted in the near future. This is one of
the sustainability issues which we need to address in an efficient manner. Thus the use of alternative
sources for construction materials which cans substitute the use of virgin materials in order to reduce
environmental impact has gained a lot of importance. These days on the other hand, disposal of waste
generated from the demolition of old structures and construction activity is also an important
environmental problem. Hence recycling and reuse of these wastes may reduce the depletion of natural
resources and help in maintaining sustainable environment. A large number of researchers are working
worldwide to understand the behavior of recycled aggregates(RA)and recycled aggregate
concrete(RAC).Through the present paper, the state of the art in the area, is intended to be generated.
EEFECT OF PARTICLE CRUSHING ON DILATANCY OF OFFSHORE SAND
Siddharth Prabhu N. IV Year B.E. (Civil) - (Summer internship program IIT Bombay)
Abstract: Dilatancy is an important characteristic of soil which governs its strength behaviour at high
confining pressures especially in case of foundations of offshore systems. Particle crushing is one of
the factors which are able to alter dilatancy of the soil. A study on effect of crushing on dilatancy of
soil would be empirical to understand its strength behaviour.
In this study, dilatancy was studied as a function of particle crushing at lower crushing stresses. A set
of direct shear tests were performed on samples which were crushed to various loads. The
experimental results showed that with increase in extent of crushing, dilatancy decreased up to a point
and then increased. The results also indicate that crushing takes place to a considerable extent even
after settlements have reached a near constant value.
SEISMIC PERFORMANCE OF INFILLED FRAMES
Vinyasa, G.C., Abhinandan, S., IV Year B.E. (Civil)
(National conference on Recent Trends in Geoscience, Material Science and Civil Engineering
(RTGMCE-2017), ATME, Mysuru)
Abstract: The usual practice in the analysis of reinforced concrete frame structures is to analyze the
frames with skeleton members comprising of only slabs, beams and columns. However, in reality the
structures also possess masonry infill within most of the frames, but they are ignored in the analysis
so as to minimize the computational works.
Researchers have indicated that the frames comprising of masonry panels behave significantly stiffer
as compared to bare frames. In the present study, an attempt has been made to evaluate a general
review of different macro models used for the analysis of infilled frames. The strength and stiffness of
RC infill is considered and modelled as equivalent diagonal strut using available strut width equations
proposed by various researchers. The performance of various macro models using different strut
width are compared with available experimental work and the most suitable macro model is
suggested. In order to study the performance of infilled frames and bare frame, the complete 3D
modelling is carried out using ETABS software. The seismic analysis is carried out using equivalent
static analysis. Finally, the performance of infilled frames is measured by comparing the period, and
lateral displacement in structural members.
Applications of Fly Ash
Dr. K. Prakash, Professor & Head
Significant research work has been carried out in the recent past and is being carried
out on the utilization of fly ash in various multidisciplinary applications in the fields such as
geotechnical engineering, cement & concrete industry, construction industry, agriculture,
mining sector and the like. With more and more understanding of the properties of fly ash
and its appropriate characterization, its potential and usefulness as a value added product
have become clearly visible. More and more possibilities of novel applications are being
brought to light.
Fly ashes have been found to be a material of high potential. It can be considered as a
multifaceted material, which has multidisciplinary and multidimensional applications. At
present, various applications of fly ash are broadly classified in to three categories.
1. High Value utilizations
Mineral extraction
Ceramic industry
Floor and wall tiles
Acid refractory bricks
Fly ash distempers & paints
Extraction of cenospheres
2. Medium value utilizations
Pozzolana cement
Cellular cement
Fly ash concrete
Fly as bricks & blocks
Prefabricated building blocks
Light weight aggregates
Grouting
Soil amendment agents/Fertilizers
Soil stabilization
3. Low value utilizations
Embankment and dam construction
Mine filling
Back filling
Structural fills
Road construction
Mass concreting
Ash dykes
The very basic classification of fly ash applications such as high, medium and low
value utilizations appears to be a misnomer. Low value utilizations are considered so as they
use fly ash, which is abundantly available, eagerly waiting for its safe disposal. High value
utilizations, probably, get that name by virtue of the high value of the products, which
sometimes may have superior qualities, derives from fly ash, a so considered waste.
However, in terms of the quantity of fly ash that can be disposed off in an economical way
through mass applications, their impact on socio-economic life of the society and derived
benefits from such applications in the long run, their value can not be considered low and in
fact, it stands above all other applications, provided if the projects involving such
applications are planned and executed appropriately, making use of the latest technology and
echo-friendly approaches.
Unfortunately in the Indian scenario, even though huge money is being spent on fly
ash research and in spite of many conferences & symposia held to educate the people about
the gainful use of fly ash in various socio-economic applications, which is unfortunately
restricted to only academicians & researchers, the public awareness level about the potentials
of fly ash is very low. This fact supplemented by the unwillingness of the governments to
implement law enforcing the use of fly ash in bulk applications in even public sector
construction activities is responsible for the failure of the low value and medium value
utilization projects. The lack of appropriate technological know-how, sophisticated
instrumentation, their cost of installation, running and maintenance and more than all, the
inferior quality coal producing fly ash in India is responsible for the failure/unsatisfactory
performance of high value utilization projects.
Since fly ashes are the materials with a very high potential, the full utilization of the
same is possible only through a coordinated efforts and approaches by different research
organizations, academic institutions, individuals, governments and the general public.
Is Soil a Boon or Bane to Construction Industry? Dr. S.K. Prasad, Professor of Civil Engineering
If you are asked to name the most common and most popular construction material,
the answers will be concrete, cement, steel etc.,. Perhaps no one will ever think that soil is the
most used construction material. If you are constructing an earth dam or an embankment, the
entire structure is made up of soil. Further, unlike other construction materials, soil exists in
nature and is available free of cost. At the most, one may have to spend on transportation to
the site, if good quality soil is not available at the location of construction. Hence, I wish to
state that soil is the most common, most used and least expensive construction material.
Besides, every structure should be built on ground, i.e., soil. The forces from structure are
taken by the reaction from ground. Hence, ground and hence, soil is most important for Civil
Engineers. Some of the important applications of soil in construction field are soil as
construction material (for earth dams, embankments etc.,.), for the manufacture of bricks,
tiles and earthenware, as fill material behind retaining walls, abutments and Foundations, as
Impermeable barrier etc.,.
If you are asked to identify the most complex construction material, without doubt,
you can mention that soil is the most complex. It is very difficult to understand the behaviour
of soil and to predict its performance. Unlike steel or perhaps concrete, it is not easy to
estimate the material property, load carrying capacity, yield strength, ductility characteristics
etc. of soil. The main reasons for complex behaviour of soil are that it is porous, polyphasic,
permeable, particulate, heterogeneous, anisotropic, non-linear in behaviour, pressure level
dependent, strain level dependent, strain rate dependent, temperature dependent, undergoes
volume change in shear etc., among many. However, it possesses many interesting and
intelligent characteristics too. To name a few, soil is colorful, it is sensitive, it possesses
memory and it changes its properties with time. All these characteristics match the behaviour
of human beings. Hence, soil should be treated as material with life, unlike steel which can be
considered as inert. If we understand soil well and respect it, it performs according to our
interest and requirements. Otherwise, it will hit back and show its displeasure in the form of
failures.
Considering these aspects, it is important to assess the properties of soil very well. It
is also necessary to identify vulnerable situations while using soil as construction material. If
any soil is found to be difficult to handle, experts should be consulted for recommendation.
Any mistake can lead to catastrophic failures.
Two case studies are presented briefly in this article, (i) Shangai Building Collapse in
2009 due to poor understanding of geotechnical engineering, and (ii) Trans Tokyo Bay
Highway in 1997, where the weakness of soil was very well identified. Under difficult
conditions, a marvelous under sea tunnel and over sea bridge structure were built, and they
are performing very well.
Shangai Building Collapse
It is common in big cities like Shangai that residential flats in the form of tall
structures are mushrooming due to the scarcity of space. One such residential complex
consisting of many towers was near completion. At 5:30 am on 27th June 2009, an
unoccupied building still under construction at Lianhuanan Road in Minhang district of
Shanghai toppled. One of the workers was killed. A 70m section of flood prevention wall in
nearby Dianpu River had suffered some cracks. Special geological condition in water bank
area might have increased vulnerability. But, these factors are not the basic reasons for this
accident.
An underground garage (planned after the construction) was being dug on south side
to a depth of 4.6 m close to the building after the construction. Excavated muck was being
piled up on north side to a height of 10 m. Unfortunately, it rained heavily resulting in water
seeping in to the ground. Building experienced uneven lateral pressure up to about 30000 kN
from south and north greater than precast hollow concrete piles could tolerate. This lateral
pressure was due to the reduced confinement on the south side, increased surcharge on the
north because of piling up of muck, accompanied by seeping water. The piles snapped at
around 2 m depth below the base of the building. Thus building toppled in south direction as
shown in Fig. 1.

Trans Tokyo Bay Highway
In established and busy cities with population of over 150 lakhs, there will always be
a need for improving transportation facility. Tokyo is no exception. With improvement in
urbanisation in Kisarazu region (eastern part), traffic flow from down town to this region
increased and vehicles had to move along Tokyo bay to reach the destination. Covering 60
km was taking more than 2 hours. Hence, it was proposed to build a road across Tokyo Bay
in sea for a distance of around 15 km which would take less than 15 minutes for travel. There
were many challenges such as (i) relatively deep sea of over 25 m in Tokyo Bay, (ii) Tokyo
harbour being one of the busiest harbours experiencing heavy traffic of ships, (iii) Poor
ground conditions at the sea bed and near the shore, and (iv) Very high seismic activity.
Above all, it was necessary to provide a facility that was environment friendly and that was
not causing any environmental impact either during construction or after. Hence, many
alternatives were planned, discussed, and their viability was assesses, and finally, one
proposal was accepted by all concerned. The following were the time lines proposed and
were strictly adhered to till the end.
May 1971: Technical investigation started.
May 1983: Japanese Government approved the construction.
October 1986: Trans-Tokyo Bay Highway Corporation was established.
May 1989: Construction started.
December 1997: Construction completed & highway was opened to public on 18th Dec.
As you see in Fig. 2, the highway comprises of three portions, a tunnel below the sea
bed for a length of 4.7 m, another tunnel for a length of 4.7 m below the sea and a bridge for
a length of 4.4 m. The first tunnel connects Ukishima access and Kawasaki man-made island.
The second tunnel connects Kawasaki man-made island and Kisarazu man-made island. The
bridge connects Kisarazu man-made island with Kisarazu. The challenges included the
construction of two man made islands in sea (i) Kawasaki man-made island and (ii) Kisarazu
man-made island. The construction involved many more challenges which included tunneling
in soft soil below sea bed. For this purpose, many ground improvement techniques such as
deep mixing were adopted to enhance the strength just enough to hold the soil from total
collapse during tunneling and keep the strength low enough not to cause additional difficulty
for excavation. Bridge construction was another challenge and it was necessary to build a
structure that does not corrode soon. Without any accident, the entire project was executed
and the infrastructure is providing excellent service since inception.

The two cases are discussed here to reveal that poor understanding of soil and its
behaviour such as in Shangai building collapse may result in accidents leading to catastrophe.
However, proper understanding of ground behaviour and its limitations can help in using the
soil to our advantage. Hence, as civil engineers, it is our duty to understand soil well and to
use it to our requirements. Wherever, expertise is required, we should not hesitate to seek
recommendations from the experts.
Measurement of Pavement Roughness Using Smartphone Application Dr. P. Nanjundaswamy, Professor
Highways, among various infrastructural facilities, plays a vital role in the overall
socio-economic growth of a country. Highways are key part of the people in their lives. Road
smoothness is one of the most important road condition measure and primary indicator of the
utility of roads. Road users can avoid or be cautious of the bad road ahead by using road
surface condition information. In addition, road surface condition information is very useful
for road authorities. The information is very important as it can be applied in decision making
processes especially for strategic planning such as asset management planning, maintenance
planning and programming. Maintaining and monitoring road infrastructure is a challenging
task for almost all governments and road authorities. One of the reasons is that the task
requires the collection of substantial amount of road network condition data, which is very
important for the maintenance planning and monitoring, over time, in addition to the
significant efforts that have to be directed to actual maintenance of the road network. Due to
this demand initiates the development of the road surface inspection system.
Road surface condition or pavement condition is generally defined by the irregularity in
the pavement surface that adversely affects the ride quality of a vehicle, thus the road users.
The irregularities may be in the form of surface unevenness, potholes, cracks, etc. (Figure 1).
Figure 1. Irregularities in the pavement surface that adversely affects ride quality
Bad road condition can cause damages to vehicles, increase fuel consumption,
increase road user costs for vehicle maintenance, unpleasant driving comfort, and sometimes
cause traffic accidents. Hence monitoring the road surface conditions has gained a significant
amount of attention.
Understanding condition of road surface is very important especially for road
maintenance and asset management. For many decades, roughness is an internationally
accepted indicator to which it is usually used to measure the ride quality of the pavement.
The World Bank established the International Road Roughness Index (IRI) as a standard to
measure road roughness. Roughness is an important pavement characteristic because it
affects not only ride quality but also vehicle delay costs, fuel consumption and maintenance
costs.
There are many approaches to obtain road surface condition data, however almost all
of them are either low speed with intensive human intervention techniques (visual inspection)
or techniques that require advanced measurement equipment (sophisticated profilers), which
usually comes with high costs and requiring skillful operators.
For developing countries, where budget and infrastructure are still limited, high-tech
approaches may still be a little out of reaches and as a result a low speed with intensive
human intervention approach may be an unavoidable option. However, with the need to
update the information regularly, this may put further pressure on road authorities in terms of
budget for maintenance, particularly. Using smartphone to collect data is a promising
alternative because of its low cost and easy to use features in addition to its potentially wide
population coverage as probe devices. Therefore, exploring the use of smartphones to
estimate road surface condition may be a great help. On one hand, smartphones already have
sensors that are capable of recording useful signal for road surface condition estimation
similarly to those used in many high-tech profilers. On the other hand, number of smartphone
users is rapidly increasing, meaning that chance of having plenty of data with inexpensive
investment is huge. Furthermore, the approach may also be useful for continuous monitoring
the soundness of road infrastructure as a whole. For this purpose, the approach is useful not
only for developing but also for developed countries.
Smartphones nowadays usually come with many useful sensors. A 3D or 3-Axis
accelerometer is one of the most common sensors that can be found inside a smartphone.
Accelerometer sensor gives us the acceleration measurements in m/s2 along each of x, y, z
axes. It can be used to recognize the motion activities. In smartphones, accelerometers are
originally used for detecting the orientation of the screen as well as in some user interfaces
and applications. As most smartphones now have a high quality built-in camera and GPS, it
is easy to take localized photos and position them on the map. This is recognized as a very
good support for visual inspections, and can also be used to capture dynamic events, such as
certain snow conditions or other maintenance contract issues.
There are some researches and studies that have explored the use of standalone
accelerometers and accelerometers that come with smartphones to detect road bumps and
anomalies. However, majority of these studies focus mainly on identifying and locating
anomalies. Gonzalez et al. (2008) use a standalone accelerometer to fit in a simulation car
and use it to assess road roughness condition. Their simulations conclude that roughness of
the road can be estimated from acceleration data obtained from the sensor. Eriksson et al.
(2008) also develop a system that utilizes standalone accelerometers to successfully detect
road anomalies. Mohan et al. (2008) use many sensing component from mobile phone such as
accelerometer, microphone, GSM radio, and GPS to monitor road and traffic condition. By
analyzing data from the sensors, potholes, bumps, braking and honking can be detected. The
information is then used to assess road and traffic conditions. Mednis et al. (2011) and
Strazdins et al. (2011) use an Android smartphone device with accelerometer to detect
location of potholes. Their approach includes many simple algorithms to detect events in the
acceleration vibration data. Tai et al. (2010) and Perttunen et al. (2011) analyze data obtained
by smartphone accelerometers in frequency domain to extract features that are corresponding
to road bumps.
Thus, application of smartphones in estimating road surface condition, especially
classifying roughness condition of road sections, by simple techniques and with the estimated
road surface condition being made available for Road Management System, road
maintenance programming and planning, in particular, are believed to be more efficient and
updated. The conceptual flow of the approach is shown in the figure 2 below.
Figure 2. Conceptual flow of the approach
Concluding Remarks
Measuring roads with smart phones can provide an efficient, scalable, and cost-
effective way for road organizations to deliver road condition data. With the assumption that
rough estimation of road surface condition from smartphones would be helpful enough for
road management and planning, provided that the approach is very low cost, easy to operate
and can be implemented frequently. In the long run, it is hoped that the approach can be used
to significantly reduce the cost of acquiring pavement roughness data which is very important
for the maintenance planning and monitoring, over time and to reduce user costs for the
traveling public by providing more robust feedback regarding route choice and its effect on
estimated vehicle maintenance cost and fuel efficiency. By broadcasting road condition
warnings through standards for ITS, the information could provide new kinds of dynamic and
valuable input to automotive navigation systems and digital route guides for special traffic,
etc. and eventually perhaps even a measure of safety.

Concrete Solutions for Climate Change
Siddharth Prabhu N. IV Year B.E. (Civil)
Climate change has been a trending topic of discussions lately. Many agree with the
argument that climate of our planet is changing, and then there are those who simply brush
off these claims. Scientific evidence suggests that Earth’s climate has always been altered
throughout its history. In fact, previously, there had been seven cycles of glacial advance
and retreat generally known as ice ages. If it is a natural process why bother now? The real
cause for concern is not that climate is changing today, but most of it today is human
induced. The main cause can be attributed to Greenhouse effect caused by gases like CO2,
methane, water vapor, nitrous oxide, CFCs etc.
Concrete, being the most used substance on earth per capita after water, has direct
association with CO2 emissions and hence the climate change. It is estimated that concrete
industry contributes to about 5% of worldwide emissions which is a significant amount.
Another drawback in employing concrete is the problem of disposal of inoperative
structures. Generally such demolished structures are piled up in landfills. Thus, in such sites,
percolation of water is affected. Also requirement of water for concrete from cradle to grave
is huge. All of these aspects have direct or indirect implications on climate change.
Therefore, time has come for civil engineers to put on their thinking cap and search for smart
solutions.
This challenge can be tackled by bearing in mind the following considerations
Greenhouse emissions
Energy saving
Recycling
Accessibility
Greenhouse emissions
Environmental pollution is a chief cause for poor air quality, particularly in urban
areas.
Different professionals tackle these issues from their own perspectives. Some path breaking
research has been done in concrete industry also. One of them is introduction of photo
catalytic materials in construction. This pioneering work can lead to safe and sustainable
environment. It is simple in its action. A photo catalytic material is mixed with concrete.
This absorbs the various pollutants present in air like carbon monoxide (CO), oxides of
nitrogen(NOx), volatile organic compounds(VOCs).Whenever sunlight is available concrete
oxidizes these pollutants and neutralizes their effect. Organic dirt particles are decomposed
on the surface and a simple wash can keep the surface clean. Thus Problems relating to
staining and discoloration of surface are also solved. With a result we have, a self-cleansing
and pollution Eating concrete. The action is throughout its life span as long as sunlight falls
on it. If surface area is larger, then effectiveness could be increased. It could perhaps be
used on the roof or pavements. This technology if popularized could have far reaching
implications.
Energy saving
Everything that gets produced is associated with certain amount of energy. The sum
total of all the energy spent from creating to disposal that product is called embodied
energy.
Conservation of this energy can directly and indirectly reduce emissions and carbon
foot prints. In the production of concrete, the energy is involved in, manufacture of cement,
transportation of aggregates and cement, mixing, batching, compaction, curing, and also in
disposal. Estimated embodied energy of concrete (1:1.5:3) is 1.11 MJ/kg. One brick
building has embodied energy equivalent to burning of 32000 liters of petrol. Reduction of
this energy is of utmost importance. Using of eco-friendly materials in the construction is
one such solution. Bamboo, sorghum wood, hemp are some of the potential candidates.
Clearly these materials absorb CO2 as they grow and release oxygen, quite contrary to the
conventional materials. In addition it has been found that use of mixture of hemp in concrete
could absorb about 165 kg of carbon and lock it in a cubic meter of concrete for many
decades. In process of mixing, batching, transportations, technological innovations are
necessary. Conservation of water is too an essential requirement. Use of waste water and
saline water could help in addressing this issue.
Recycling
In the factors mentioned above, this particular factor provides wide scope for
improvement. Humans produce large amount of waste and a significant quantity is
recyclable or reused. The reuse of these post-consumer wastes in concrete will be ideal to
meet climate change challenges.
Concrete debris forms the core waste produced in construction industry. Reusing of these as
aggregates in concrete would achieve two objectives. One, it would reduce the huge
aggregate requirement which is getting exhausted. And two, it can take care of the waste
which otherwise would have been dumped in any landfills. Cost is another criterion.
Emissions will be generally reduced as new raw materials are not used. Some of the
innovations in recycling are use of plastics in pavements, use of glass as aggregates, use of
gray water, foundry sand and slag. Other solid waste which could be used in concrete is
glass, fly ash, wood ash, and pulp and paper-mill residue.
Accessibility
Early decades of previous century, energy in general was too expensive in the sense
that it was not affordable to common man. In the turn of century, various sources of energy
were discovered, production increased, cost decreased and energy became more accessible.
However, this downward trend in cost also implied a drastic increase in emissions and in
turn climate change. Now, to decrease this effect, path traced by emissions must be retraced,
but in opposite direction. That is to say that, the smart solutions suggested above must
become cost effective and more accessible to the common public. People will only accept it
until they are made known of its uses. Awareness has to be created. To commercialize these
products provides one with tremendous amount of business opportunities.
In conclusion, climate change is clearly inevitable. We must not think of the problem
we have created but rather think of ingenious methodology of eradicating it. With countries
like India pledging to curb its carbon emissions to up to 30% by2030 through its Intended
Nationally Determined Contribution (INDCs), these methodologies could help it to achieve
it to some extent. This is synonymous with Prime Minister, Modi’s pet project of building
100 smart cities where changes can be encompassed in planning stages itself. Thus, creating
a cleaner, safer, sustainable place to live in.
