Opportunities &
Challenges

2. What is Eco-Concrete ?
 ECO- concrete is a revolutionary topic in the history of
concrete industry. This was first invented in Denmark in
the year 1998. ECO- concrete has nothing to do with
color. It is a concept of thinking environment into
concrete considering every aspect from raw materials
manufacture over mixture design to structural design,
construction, and service life.
 ECO- concrete is a type of concrete which resembles
the conventional concrete but the production or usage
of such concrete requires minimum amount of energy
and causes least harm to the environment.

3. Environmental Goals :
ECO- Concrete is expected to fulfill the following
environmental obligations:
 Reduction of CO2 emissions by 21 %. This is in accordance
with the Kyoto Protocol of 1997.
 Increase the use of inorganic residual products from
industries other than the concrete industry by approx. 20%.
 Reduce the use of fossil fuels by increasing the use of waste
derived fuels in the cement industry.
 The recycling capacity of the ECO- concrete must not be
less compared to existing concrete types.
 The production and the use of ECO- concrete must not
deteriorate the working environment.
 The structures do not impose much harm to the
environment during their service life.

4. Advantages of Eco-Concrete :
 ECO-concrete has manifold advantages over the
conventional concrete. Since it uses the recycled
aggregates and materials, it reduces the extra load in
landfills and mitigates the wastage of aggregates. Thus,
the net CO2 emissions are reduced.
 The reuse of materials also contributes intensively to
economy. Since the waste materials like aggregates
from a nearby area and fly ash from a nearby power
plant are not much expensive and also transport costs
are minimal.
 ECO-concrete involves reduction of amount cement in
the mix, this practice helps in reducing the consumption
of cement overall.

5. Several other advantages related to ECO-concrete :
 Reduced CO2 emissions.
 Low production costs as wastes directly substitute the
cement.
 Saves energy, emissions and waste water.
 Helps in recycling industry wastes.
 Reduces the consumption of cement overall.
 ECO-concrete is having good thermal and fire resistant.
 Better workability.
 Sustainable development.
 Greater strength and durability than normal concrete.
 Compressive strength and Flexural behavior is fairly equal
to that of the conventional concrete.
 ECO-concrete might solve some of the societies ‘problems
with the use of inorganic, residual products which should
otherwise be deposited.

6. How to produce ECO-concrete :
 To increase the use of conventional residual products:
 To minimize the clinker content, i.e. by replacing cement
with fly ash, micro silica in larger amounts than are
allowed today.
 By developing new green cements and binding materials,
i.e. by increasing the use of alternative raw materials and
alternative fuels, and by developing/improving cement
with low energy consumption.
 Concrete with inorganic residual products :(stone dust,
crushed concrete as aggregate in quantities and for areas
that are not allowed today) and cement stabilized
foundation with waste incinerator slag, low quality fly ash
or other inorganic residual products.

8. LIMITATIONS OF ECO-CONCRETE
Argued that green concrete can be made durable by using
stainless steel reinforcements, but the predicament is that by
using stainless steel concrete the cost of the construction
increases considerably. Even after this, eco concrete is not as
durable as the conventional concrete. The limitations of using
eco concrete can be summarized as below:
 By using stainless steel, cost of reinforcement increases.
 Structures constructed with green concrete have
comparatively less life than structures with conventional
concrete.
 Split tension of green concrete is less than that of
conventional concrete.
 Not as durable as conventional concrete.

9. SCOPE IN INDIA
 Concrete is an indispensable entity for a developing
country like India which desperately needs a
continuously expanding infrastructure.
 India is the second largest producer of cement in the
world. Further India would be facing an exponential
growth in the concrete demand by 2020.
 Being produced in voluminous quantities in India, the
concrete industry has a considerable part in the net CO2
emissions from the country. The net CO2 emissions from
the construction agency are greater than any other
industry.

10. Conclusions :
 Apart from several limitations coupled with the urgent
need of reduction in green house gas emissions, has
sparked off a number of researches across the globe to
make green concrete more durable and bring it up to
the mark with conventional concrete.
 So definitely use of concrete product like GREEN
CONCRETE in future will not only reduce the emission of
CO2 in environment and environmental impact but also
economical to produce.
The above facts clearly state a wide and promising
scope of Green Concrete in the Near Future.
