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.

Keywords
