ABSTRACT
There is a growing awareness in India about extensive
damage being caused to the environment due to accumulation
of waste materials from industrial plants, power houses,
colliery pits and demolition sites and it has become one of the
major environmental, economical and social issues. Waste
material is the material unused, unwanted and rejected as
worthless into the environment in our society as whole. Waste
materials coming out of industry nowadays is posing a great
environmental problem in disposing them into the air, water
and on the land. But, with proper utilization of these materials
in construction industry as well as in making road pavements
will greatly help the society to have a better and pleasant
environment. Substitution of waste materials will conserve
dwindling resources, and will avoid the environmental and
ecological damages caused by quarrying and exploitation of
the raw materials for making cement. These waste materials
can partly be used, or processed, to produce materials suitable
as aggregates or fillers in concrete. Use of waste products is
not only a partial solution to environmental and ecological
problems and it significantly improves the microstructure, and
consequently the properties of concrete. The output of these
waste materials in India are more than double the production
of cement and other construction material used in all the civil
engineering activities. So, use of waste materials not only to
make the cement concrete (generally used in all the
construction activities) less expensive, but to provide a blend
of tailored properties of waste materials and portland cements
suitable for specified purpose. This paper outlines regarding
the optimum utilization of waste materials in some
construction activities as a green concept, which ultimately
reduces the environmental pollution.
