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 Does C&D Waste Consists of..

Concrete

Bricks

Timber

Sanitary waste

Glasses

Steel

Plastic

What is the Composition of C&D Waste

in India


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

Aggregate (Sand)”


IS 383 : 2015

Indian Standard

COARSE AND FINE AGGREGATE FOR

CONCRETE – SPECIFICATION

(Third Revision)


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.



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.

National Building Code of India

2005

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.
