Green concrete is a type of concrete that uses less energy and causes less harm to the environment during production compared to conventional concrete. It incorporates waste materials like recycled concrete aggregates as partial replacements for cement or standard aggregates. Using materials like fly ash also reduces the carbon dioxide emissions associated with cement production. Green concrete provides benefits like improved durability, strength, and workability while reducing the construction industry's environmental impact through lower CO2 emissions and higher waste reuse.
The concrete which is made from the industrial wastes and eco-friendly is the green concrete.Green will reduce 10% of CO2 emission which will reduce the global warming, which is one of the reason for world's destruction.Since it is made from the industrial wastes it is very cheap and durable.

As the world population grows, so do the amount and type of waste being generated.Many of the waste produced today will remain in environment.The creation of non decaying waste material, combined with a growing consumer population, has resulted in a waste disposal crisis.
One solution to this crisis lies in recycling waste into useful products.
It is try to match society need for safe and economic disposal of waste material with highway industry need for better and more cost effective construction material.
Shotcrete normally has a greater compressive strength then cast in place concrete due to lower water to cement ratio.
The guniting is the most effective process of repairing concrete work which has been damaged due to inferior work or other reasons. It is also used for providing an impervious layer.

2. WHAT IS CONCRETE
Concrete is the mixture of cement, sand , water
and course aggregates which can be poured into
formwork and form a hard structure like a
stone.
4. INTRODUCTION : GREEN CONCRETE
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 is much like the
conventional concrete but the production of such concrete
requires minimum amount of energy and causes least harm to
environment .
Green concrete has nothing to do with colour.

5. WHATIS GREENCONCRETE?
5
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 reduced
environmental impact for e.g. Energy saving ,co2
emissions, waste water.
6. Green concrete can be defined as the concrete with material as a
partial or complete replacement for cement or fine or coarse
aggregates.
The substitution material can be of waste or residual product in the
manufacturing process.
ACTUAL DEFINITION:-
7. Why Green Concrete ?
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.
9. Materials for GreenConcrete
Coarse Aggregates are:
Fresh local aggregate Recycled Demolition Waste Aggregate
Recycled Concrete Material (RCM) Blast Furnace Slag (BFS)
10. Materials for GreenConcrete
Fine Aggregate s are:
Fly Ash
Blast Furnace Slag (BFS)
Manufactured Sand For Concrete Recycled Glass Aggregate
11. Cementitious materials – ‘Fly Ash’
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.
12. Advantages Of Using Fly Ash in Concrete:
1.Utilization of fly ash as a part replacement of cement or as
a mineral admixture in concrete saves on cement and hence
the emission of CO2.
2.Use of good quality fly ash in concrete has shown
remarkable improvement in durability of concrete, especially in
aggressive environment.
13. a) Higher ultimate strength
b) Increased durability
c) Improved workability
d) Reduced bleeding
e) Increased resistance to alkali-silica reactivity.
f) Reduced shrinkage.
Someof the technicalbenefitsof theuseof flyashin GreenConcreteare:
14. 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 selfload
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.
The 28day cube compressive strength of the resulting lightweight aggregate
concrete with density of 1590 kg/m3 and respective strength of 34 MPa.
Most of normal weight aggregate of normal weight concrete is natural stone such
as limestone and granite.
Green lightweight aggregates
15. APPLICATIONS:-
• Following are the major applications of green
concrete :-
1. It is used in the construction of bridges.
2. It is widely used in the building construction.
3. Used in the construction of columns.
4. Can be used in road construction.
17. SUITABILITYOF GREENCONCRETEIN STRUCTURES
Several factors which enhances the suitability of green concrete in structures
include:
1. Reduce the dead weight of a structure of a facade from
5 tons to about 3.5 tons.
2. Reduce crane age load; allow handling, lifting flexibility with lighter weight.
3. Good thermal and fire resistance, sound insulation than the traditional granite
rock.
4. Reduction of the concrete industry's CO2-emission by 30 %.
5. Increased concrete industry's use of waste products by 20%.
6. No environmental pollution and sustainable development.
7. Green concrete requires less maintenance and repairs.
18. =: ADVANTAGES:-
1.Green concrete having better workability than conventional concrete.
2.Reduction in shrinkage & creep.
3.Green Concrete uses local and recycled materials in concrete.
4.The heat of hydration of green concrete is significantly lower than traditional
concrete.
5.Good thermal resistant and fire resistant.
6.Compressive strength and Flexural behaviour is fairly equal to that of the
conventional concrete.
19. LIMITATION
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.
20. Green concrete is a revolutionary topic in the history of concrete
industry.
As green concrete is made with concrete wastes it does not take more
time to come in India because industries having problem to dispose
wastes.
Also having reduced environmental impact with reduction in CO2
emission.
SCOPEIN INDIA
21. CONCLUSION
Green concrete having reduced environmental impact with reduction of the
concrete industries CO2 emissions by 30%.
Green concrete is having good thermal and fire resistant.
In this concrete recycling use of waste material such as ceramic wastes,
aggregates, so increased concrete industry’s use of waste products by 20% .
Hence green concrete consumes less energy and becomes economical.
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.``
