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.
