Abstract:
With the rapid rate of global urbanization and industrialization, there is an intense
development around the globe. This call for a non-ending need of resources (both
natural and artificial) and leaves behind huge piles of wastes. In developing
countries like in India, generally C&D waste is not properly disposed in an
unorganized manner thereby leading the problem of environmental issues.
However these days globally research work is done regarding recycling and for
devising new applications to make more sustainable environment. Concrete is the
premier construction material across the world and the most widely used in all
types of civil engineering works. In the past, aggregates were readily available at
lower prices and qualities to suit all purposes. However, in recent years the
uncontrolled quarrying and use of aggregates from natural resources has led to the
depletion of primary aggregates and has created greater awareness of
environmental protection. This paper explores a theme on the use for recycled
concrete aggregates and highlights its potential use as aggregate in rigid pavement
construction along with various techniques and applications involved in the
process. The effect of adhered mortar on the properties of aggregate particle along
with various methods proposed by different studies in the past for their removal is
discussed in the study. Also established rules or specifications for
incorporating recycled concrete aggregates by different countries are discussed
in study.
