Abstract

This study incorporates fine waste glass (GS) as a replacement for natural sand (NS) in fly ash (FA) based alkali activated mortar (AAm). AAms were heated at elevated temperature of 200℃, 400℃, 600℃, and 800℃ to explore the residual mass, compressive strength, thermal expansion and change in microstructure of matrix. Results showed greater resistance of AAms with increasing GS content to 50% at each temperature. Owing to the melting of GS at 800℃, the greater matrix bond was observed for AAm incorporating 75% and 100% GS as a result, the residual compressive strength was increased.
