Abstract
In this research experimental study was carried out on how to use recycled crushed glass as
partial replacement of coarse aggregate for structural concrete and decorative concrete
purpose for production of terrazzo.
The research was carried out by conducting laboratory tests for concrete making materials
(coarse aggregate, fine aggregate and recycled crushed glass). Concrete mix design was
prepared for C25 and C30 classes of concrete using ACI mix design procedure. The coarse
aggregate in each grade of concrete was replaced by recycled crushed glass at 10%, 20%
and 30% by weight. The control mix without incorporation of recycled crushed glass was
prepared which was used as reference for comparison of test results with those specimens
produced by partial replacement. Generally 8 concrete mixes were prepared including the
control mix for both C25 and C30 classes of concrete.
Slump test was conducted for each grade of fresh concrete. The properties of hardened
concrete were studied by conducting compressive strength, flexural strength and splitting
tensile strength tests. The compressive strength test was carried out at the 3
day, whereas the flexural and splitting tensile strength tests were carried out at the 28
Furthermore, terrazzo concrete was prepared by partially replacing coarse aggregate at 10%,
20% and 30% with recycled crushed glass. Laboratory tests were conducted on the terrazzo
at the 28
th
day. The tests conducted were water absorption, surface water absorption and
transverse strength.
The test results obtained by partial replacement were compared with the result of the control
mix. In line with it the results obtained by concrete specimens produced by partial
replacement were slightly greater than that of the control mix. The general result reveals that
recycled crushed glass can be used for structural concrete and for decorated concrete
purposes.
