FLY ASH-BASED GEOPOLYMER MORTAR INCORPORATING BOTTOM ASH

Djwantoro Hardjito, Shen Shaw Fung

Abstract


This paper presents the results of study on effect of various parameters on mechanical properties of fly ash-based geopolymer mortar with bottom ash as partial or full replacement for sand. Compressive strength of samples with 10% bottom ash (BA) was comparable to those with only sand. Further increase in bottom ash content decreased the compressive strength. However, the reverse tendency occurred after exposing the samples to 1000oC for 24 hours.
