Green concrete is a more sustainable type of concrete that uses less energy and causes less harm to the environment during production. It incorporates waste materials like fly ash, rice husk ash, and recycled aggregates as partial replacements for traditional ingredients like cement and virgin aggregates. Green concrete has benefits like higher strength, increased durability, and reduced shrinkage compared to normal concrete, while also lowering costs and carbon dioxide emissions. It shows potential to grow in use for construction in India as it addresses needs for sustainable building materials and waste disposal.

6. Green concrete is revolutionary topic in the history of
concrete industry , this was first invented In Denmark
in year 1998
Green concrete is the type of concrete which like the
conventional concrete but a production of such
concrete requires minimum amount of energy and
causes least harm to environment
INTRODUCTION :-

7. What is Green Concrete ?
 A concrete that made with concrete waste
and uses less energy in its production & produces less carbon
dioxide than normal concrete.
 This is called eco-friendly and reduces environmental
impact.

8.  The main ingredient in concrete is cement and it
consists of Limestone (Calcium Carbonate CaCO3).
 During manufacture of cement, its ingredients are
heated to about 800 - 10000C.
 During this process the Carbon Dioxide is driven off.
 Approximately 1kg of cement releases about 900gms of
Carbon Dioxide into the atmosphere.
 Therefore, green concrete came into existence to
reduce the emission of carbon dioxide.
WHY GREEN CONCRETE..?

9. MATERIALS USED IN GREEN CONCRETE :-
Coarse Aggregates are :-
Recycled Demolition Waste Aggregate
Fresh local aggregate
Recyclable Concrete Material
Blast Furnace Slag (BFS)
1)Coarse Aggregates. 2)Fine Aggregates.

10. MATERIALS USED IN GREEN CONCRETE :-
Fine Aggregates are :-
Manufactured Sand For Concrete
Fly Ash
Rice Husk Ash (RHA)
Recycled Glass Aggregate
10

11. Fly ash is a by-product produced during the operation of coal-fired power
plants. The finely divided particles from the exhaust gases are collected in
electrostatic precipitators. These particles are called Fly ash.
Rice Husk is the hard protecting coverings of grains of rice. Further it
combusted & converted in Ash by heating around 400 – 800 degree Celsius.
Rice Husk ASH & Fly ASH:-
The mixture used in Green Concrete is – 40% Fly ASH & 10% Rice Husk
ASH.
Ratio is (4:1). When this amount of ratio is mixed in Green Concrete , it
will provide the best compact & high advantages for it.
CEMENTIOUS MATERIAL – Fly Ash &
RHA

12. Advantages of
ASH Rice Husk & Fly ASH
in Green Concrete :-
Utilization Fly ASH & Rice Husk ASH as a part
replacement of cement or as a mineral admixture in
concrete saves on cement and hence the emission
of CO2.
Use of good quality fly ash & rice husk ash in
concrete has shown remarkable improvement in
durability of concrete, especially in aggressive
environment.
Fly ASH & Rice Husk ASH make concrete green
by reducing Water content, which in turn reduces
Cement content.

13. CONTD…
a) Higher ultimate strength.
b) Increased durability.
c) Improved workability.
d) High resistance.
e) Reduced shrinkage.

17. GREEN LIGHTWEIGHT
AGGREGATES :-Synthetic lightweight aggregate
produced from environmental waste is a
viable new source of structural
aggregate material.
The uses of structural grade
lightweight concrete reduce considerably
the self-load of a structure and permit
larger precast units to be handled.
Water absorption of the green
aggregate is large but the crushing
strength of the resulting concrete can
be high.

18. SUSTAINBLITY OF GREEN CONCRETE IN
STRUCTURES :-
1. Reduce the dead weight of a structure of a facade from
5 tons to about 3.5 tons.
F = ma
2. Good thermal and fire resistance, sound insulation than the
traditional granite rock.
3. Reduction of the concrete industry's CO2-emission by 30 %.
4. Increased concrete industry's use of waste products by 20%.
5. No environmental pollution and sustainable development.
6. Green concrete requires less maintenance and repairs.

22. SCOPE IN INDIA :-
Green concrete
is a
revolutionary
topic in the
history of
concrete
industry.
As green
concrete is
made with
concrete wastes
it doesn't take
more time to
come in India
because
industries having
problem to
dispose wastes.
Also having
reduced
environmental
impact with
reduction in
CO2 emission.

23. Conclusion :-
 The review presented in this PPT
clearly indicates an increasing
trend and incentives for the greater
use of manufactured and recycled
aggregates in construction.
 Use of concrete product
like green concrete in
future will not only reduce
the emission of CO2 in
environment and
environmental impact but
it is
• also economical to
