Reuse of Discarded Glass as a Partial Replacement to Fine Aggregate and Microstructural Analysis of Solidified Matrix

Abstract

An attempt is being made in this research study
to envisage the feasibility of using waste glass as
a partial replacement to fine aggregate. Mortar
cubes using waste glass in varied proportions
were subjected to compression test at the age of
3, 7 and 28days curing. The replacement of fine
aggregates with 20% glass yield was 23.09
N/mm2, 26.89 N/mm2 and 42.50 N/mm2 which
was 16%,19% and 14% higher than control at
the end of 3, 7 and 28 days curing respectively.
The
structural
and
morphological
characteristics of the glass granules and crushed
mortar were analysed by EDX, SEM and XRD.
XRD results clearly suggested that the mortar
cube was crystalline and glass powder was
amorphous in nature.
