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.
