Abstract:
A massive amount of glass waste is produced every year all over the world, but a small
amount of this waste is being recycled. The recycling of waste glass (WG) in concrete
shows great achievements in reducing the quantity of glass. According to researchers’
addition of waste glass in concrete enhances the properties of concrete, WG can be used
in any form like powder, fine or coarse aggregate. However, from previous studies of
different researchers, it has been found that there are some ill effects of waste glass on
concrete. This inconsistency of results of waste glass between researchers affects the
acceptance (using) of waste glass in concrete structures. To overcome the formal problem
the study clarifies the debate of using or not using the waste glass in concrete depending
on the analysis of different papers. In this study, an attempt was made to experimentally
evaluate the mechanical properties of concrete with recycled glasses. The control mix was
made and the other mix containing waste glasses as replacement of coarse aggregates.
According to the slump test, the slump value of control mix was 70mm and slump value of
other mix containing glasses was 95mm. the compressive strength too has decreased
by39.9percentage.the maximum compressive strength of a control mix after 28days of
curing was 19.7 KN/m2 while the other mix with waste glasses was 11.8 KN/m2. The
incorporating of waste glasses can highly reduce compressive strength due to its lower
bonding capacity in the mix but this substitutional helps reduce waste glasses pollution.
