This research investigates the physical, mechanical, thermal conductivity, and fire-resistant properties of mortar incorporating with auto glass waste (AGW). The crushed AGW was used as fine aggregate to substitute natural sand (NS) from 0 to 100% by volume. The 40% replacement with AGW was optimum, with a slight increase in the 28-day compressive strength. The 90-day compressive strength of 100% AGW increased by 33% compared to NS mortar (without AGW) due to the increased pozzolanic reaction. The replacement of sand with AGW resulted in improvements in thermal insulation properties and fire resistance of mortars. The 100% replacement with AGW decreased the thermal conductivity coefficient by 63%, while the density decreased by only 2.8% compared to the NS mortar. The residual compressive strength increased with incorporating AGW after exposure to elevated temperatures. The 100% replacements with AGW showed a maximum compressive residual mortar strength of 66 MPa (126%) after exposure to high temperatures at 300°C.
