What is C & D Waste
Construction and demolition (C and D) waste is
defined as the solid waste generated by the
construction, remodelling, renovation, repair,
alteration or demolition of residential, commercial,
government or institutional buildings, industrial,
commercial facilities and infrastructures such as
roads, bridges, dams, tunnels, railways and airports.
Construction and demolition waste is considered as
high volume, low risk.

What is the Composition of C&D Waste
in India
17 November 2015 13New Delhi
Problems Associated With C&D
Waste
Increasing quantum of demolition’s rubble due to rapid
urbanization
Continuing shortage of dumping sites − Unauthorized
dumping
Increase in transportation and disposal cost
Depletion of natural resources

Role Of Standards In Utilization Of
C&D Wastes
Basis for acceptance
Wider use by bringing confidence in the minds of the
users
Transfer of technology
Dynamism – review/amendment/revision/withdrawal
Techno-legal - Part of regulatory documents
Techno-financial - Part of financing projects
Basis for training/capacity building and further R&D

COARSE AND FINE AGGREGATE FOR
CONCRETE – SPECIFICATION
(Third Revision)
17 November 2015 20New Delhi
IS 383 : 2015 (Under Print)
Scope :
This standard covers the requirements for
aggregates, crushed or uncrushed, derived from
natural sources, such as river terraces and riverbeds,
glacial deposits, rocks, boulders and gravels, and
manufactured aggregates produced from other
than natural sources, for use in the production of
concrete for normal structural purposes including
mass concrete works.
17 November 2015 21New Delhi
IS 383 : 2015 (Under Print)
These manufactured aggregates may be of two types
namely
Recycled Aggregate (RA) ‒‒ It is made from C&D
waste which may comprise concrete, brick, tiles, stone,
etc
Recycled Concrete Aggregate (RCA) ‒ It is derived
from concrete after requisite processing.
RA can be used as coarse aggregate and RCA can be
used as coarse and fine aggregates in accordance with
this standard.

The Part 11 of NBC 2005 on Approach to Sustainability states
that :
Recycled Coarse Aggregate may be used in concrete for
Bulk fills, Bank protection, Base/Fill of drainage structures,
Pavements, Sidewalks, Kerbs and Gutters etc.
Up to 30 Percent of natural crushed coarse aggregate can
be replaced by the Recycled Concrete Aggregate.
This percentage can be increased up to 50 percent for
Pavements and other areas which are under pure compression.

CONCLUSION
Established utilization of C&D wastes in concrete
and concrete based products for which standards
have already been developed
Quality control and certification
Need for popularizing use of wastes
R&D activities on continuous basis in tandem with
manufacturing industry and users
Achieving environment protection through waste
utilization
Optimizing utilization pattern of traditional
materials by interfacing the same with
supplementary materials.
