ABSTRACT
In order to
make concrete industries sustainable, the use of waste materials in place of
natural resources is one of the best alternatives. The environmental and
economic concern is the biggest challenge construction industries facing. The
research work investigation was conducted to study the viability of using
copper slag and waste glass powder as an alternative material for partial
replacement of fine aggregate in preparation of concrete mix. Fine aggregate
were replaced by copper slag and waste glass powder as 10%, 20%, 30%, 40%, 60%
and 80% by weight for concrete mix of M20 grade with water cement ratio 0.5.
The fresh concrete were tested for workability and concrete specimen were
tested for compressive strength at 7, 14 and 28 days of age and the results
obtained were compared with control concrete mix. The results concluded that
the workability of fresh concrete increase as the percentage of copper slag and
waste glass powder increases. The compressive strength of concrete specimen
increases up to 40% replacement level and highest compressive strength achieved
at 20% replacement of fine aggregate with copper slag and waste glass powder.
The density of concrete cubes also increases up to 40% replacement beyond that
it starts decreasing.
