Demand of Construction aggregate reach to 48.3 Billion metric tons by 2015 in Asia and Pacific.So there is a vital need for recycling of concrete in Civil Engineering field

1. CONCRETE RECYCLING
-A RECENT TREND IN CIVIL ENGINEERING

2. Auspicated in 1945

3. PLASTICS ARE RECYCLED
LIKEWISE CONCRETE CAN ALSO BE
RECYCLED

5. DEMAND OF CONSTRUCTION
AGGREGATE REACH TO 48.3
BILLION METRIC TONS BY
2015 IN ASIA AND PACIFIC

9. CAN CONCRETE BE RECYCLED?

10. YES CONCRETE CAN
BE RECYCLED

12. STEP 1

13. PRODUCTS FROM
DEMOLITION

14. STEP 2

15. BOULDERS ARE USED
FOR SUB-BASE COURSE

17. STEP 3

18. MANUFACTURING PLANT

19. STEP 4

21. CEMENT CLINKER
FOR CEMENT
MANUFACTURE

22. STEP 5

26. STEP 6

27. RECYCLED AGG.

28. RMC

29. FINALLY

30. NEW CONCRETE STRUCTURE/floors

31. MERITS
•Recycling one ton of cement
could save 1,360 gallons
water, 900 kg of CO2

32. TRANSPORTATION
•IT COSTS AS MUCH AS
25CENTS PER TON PER MILE IN
TRANSPORTATION

33. DISPOSAL
•IT ELIMINATES DISPOSAL COST AS HIGH
AS 100 DOLLAR PER TON ACCORDING TO
CONSTRUCTION MATERIALS RECYCING
