Abstract

Electronic-based Hybrid Glass Wastes (EHGW) covers computer, television, and mobile display screens. Although Hybrid Glass Waste is recycled to create a valuable new glass product, the vast majority of Hybrid Glass Waste is still disposed of in landfills. In the present study, the prime objective is to assess EHGW as a fine aggregate and filler in concrete composites. Physical and chemical assessments of EHGW are performed in detail. Thermogravimetric analysis revealed EHGW is more sensitive regarding temperature variation. Specifically, 344 °C is the observed melting point of EHGW. Predominantly, a concrete mix of M40 grade is designed with EHGW as a partial replacement to fine aggregate with the incremental rate of 5% and limiting to 20%. Slump and mechanical properties of concrete composite reveals that 10% of EHGW replacement to fine aggregate gives optimal results.  In addition, the mechanical performance of  all EHGW based concrete composite is observed and evaluated at 28 °C (ambient temperature), 115 °C (-H2O) and 344 °C (liquefaction state). Compared with control mix, the overall findings revealed a maximum loss of mechanical properties for 20% EHGW based concrete composites which is about 10.26% to 30.97% at 115 °C and 27.25% to 71.89% at 344 °C. Also, the polynomial regression represents significant relation between mechanical properties and EHGW replacement percentage with 0.82 to 0.85 R2 values.
