3. GREEN CONCRETE

4. 1. INTRODUCTION :
 Green concrete is defined as a concrete which uses waste material as at least
one of component,or its production does not lead to environmental
destruction.
 Green concrete is the revolutionary topic in the history of concrete
industry,this was first invented in Denmark by Dr. W G in 1998.
 Green concrete improves the three pillars of sustainability : environmental ,
economic and social impacts.
 The word green in green concrete is not just limited to colour.
 It should also have high performance and life cycle sustainability.
 It is a concept of using eco-friendly materials in concrete,to make the system
more sustainable.

5. 2. WHAT IS GREEN CONCRETE & WHERE It IS USED?
 A concrete that made with Concrete waste and uses less energy in its
production & produces less carbon dioxide than normal concrete is green
concrete.
 Concrete wastes like slag, power plant wastes, recycled concrete, mining and
quarrying wastes, waste glass, incinerator residue, red mud, burnt clay,
sawdust, combustor ash and foundry sand.
 Green Concrete is a term given to a concrete that has had extra steps taken in
the mix design and placement to insure a sustainable structure and a long life
cycle with a low maintenance surface. E.g. Energy saving, CO2 emissions,
waste water.

6. 3. MATERIAL FOR GREEN CONCRETE :
 Locally available : construction materials, components and systeams found
locally or regionally,saving energy and resources in transportation to the
project site.
 Salvaged,re-furnished,or re- manufactured : Includes saving a material from
disposal and renovating, repairing, restoring,or generally improving the
appearance, performance,quality, functionality,or value of a product.
 Reusable or recyclable : Select materials that can be easily dismantled and
reused or recycled at the end of their useful life.

7. Fresh Local Aggregate Recycled Demolition Waste Aggregate Recycled Concrete

8. 4. GREEN LIGHTWEIGHT AGGREGATES :
 Synthetic lightweight aggregate produced from environmental waste is a
viable new source of structural aggregate material.
 Basically two types of light weight aggregates-
Natural Aggregate
Artificial Aggregate

9. 5. APPLICATION OF GREEN CONCRETE :
Green Concrete Dam Green Concrete Bridge Green Concrete Columns

10. 6. ENVIRONMENTAL BENEFITS TO USING
GREEN CONCRETE
 Lasts Longer
 Uses Industrial Waste
 Reduces Energy Consumption
 Reduce CO2 Emissions

11. 7. THE PROPERTIES OF GREEN CONCRETE ARE:
 Workability
 Segregation
 Bleeding
 Harshness

12. 8. PRODUCTION OF GREEN CONCRETE :

13. 9. SUITABILITY OF GREEN CONCRETE IN
STRUCTURES :
 Reduce the dead weight of a façade from 5 tons to about 3.5 tons.
 Allow handling, lifting flexibility with lighter weight.
 Good thermal resistance.
 Provide good fire resistance.
 Sound insulation than the traditional granite rock.
 Improve damping resistance of building.
Speed of construction, shorten overall construction period.

14. 10. ADVANTAGES :
 Green concrete is economical compared to conventional
concrete.
 Green concrete having better workability than conventional
concrete.
 Reduces environmental pollution.
 Have good thermal and acid resistance.
 Reduces the consumption of cement overall.

15. 11. 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.

16. 12. SCOPE IN INDIA :
 Green concrete is a revolutionary topic in the history of concrete
industry.
 As green concrete is made with concrete wastes it does take more time
to come in india.
 Because industries having problem to dispose wastes.
 Also having reduced environmental impact with reduction in CO2
emission.

17. 13. CONCLUSION :
 There is significant potential in waste materials to produce green
concrete.
 Green concrete consumes less energy and becomes economical.
 Green concrete having reduced environmental impact with reduction of
the concrete industries co2 emissions by 30%.
 It helped to reduce mining of river sand.
 A detail life cycle analysis of green concrete by considering various
parameters is very much necessary to understand the resultant concrete
properties.
